4-14: Postgres credentials are hardcoded in plaintext.The
POSTGRES_USER/POSTGRES_PASSWORDvalues are hardcoded. This is acceptable for local development, but if this compose file is ever used in a shared or staging environment, consider using a.envfile or Docker secrets to avoid committing credentials to source control.🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed. In `@docker-compose.yml` around lines 4 - 14, The docker-compose service "postgres" currently hardcodes POSTGRES_USER and POSTGRES_PASSWORD environment variables; change this to load credentials from a safer source by replacing the literal values with environment variable references (e.g., ${POSTGRES_USER}, ${POSTGRES_PASSWORD}) or Docker secrets, and add instructions to read them from a .env file or secret named accordingly; update any documentation or examples to include a sample .env with placeholders and ensure the compose file references the same variable names for the postgres service and POSTGRES_DB to avoid committing plaintext credentials.

3-4: Maven orb is imported but never used.
circleci/maven@1.2.0is declared but no orb commands or jobs are referenced anywhere. Either leverage the orb's built-inmaven/testjob or remove the import to avoid confusion.🤖 Prompt for AI Agents
Verify each finding against the current code and only fix it if needed.

7-14:type: LoadBalanceris redundant when an Ingress is also defined.The Ingress already handles external routing to this Service. Using
LoadBalancertype provisions an additional external load balancer, which is unnecessary cost in cloud environments.ClusterIP(the default) is typically sufficient when traffic arrives via Ingress.♻️ Proposed fix

37-37: UnnecessarySecurityContextHolderupdate in a stateless session.
SecurityConfigsetsSessionCreationPolicy.STATELESS, so the security context is not persisted across requests. Setting authentication here has no lasting effect — the token is generated and returned immediately after. This line can be removed to avoid confusion.🤖 Prompt for AI Agents

47-67: Consider using a Java record forLoginRequest.Since the project targets Java 17, the inner

Inline comments:
In @.circleci/config.yml:
- Around line 6-9: The build-and-test job is missing an executor; add an
executor block to the job `build-and-test` (either `machine:` or `docker:`) —
for example use a Docker executor with `image: cimg/openjdk:17.0` to avoid
manual JDK installs — and remove any now-unnecessary `sudo apt-get` JDK
installation steps so the job runs with the provided runtime image.
In `@Dockerfile`:
- Around line 1-9: Replace the deprecated base image and stop running as root:
change the FROM image to an Eclipse Temurin JDK (e.g., use
"eclipse-temurin:17-jdk") and create a non-root user in the Dockerfile, chown
the application files (refer to COPY app.jar and WORKDIR /app), and switch to
that user before the ENTRYPOINT; ensure the ENTRYPOINT
(["java","-jar","app.jar"]) runs as the non-root user and keep EXPOSE 8080
unchanged so the container follows least-privilege practices.
In `@kubernetes/deployment.yaml`:
- Around line 16-40: Add a restrictive container securityContext for the
spring-boot-app container to prevent running as root and disable privilege
escalation: set runAsNonRoot: true and a non-zero runAsUser (e.g. 1000), set
allowPrivilegeEscalation: false, drop all Linux capabilities (capabilities:
drop: ["ALL"]), enable readOnlyRootFilesystem: true and set seccompProfile: {
type: RuntimeDefault } (or equivalent). Update the spec under the container
named "spring-boot-app" (near readinessProbe and livenessProbe) to include these
fields so the container no longer runs as root and privilege escalation is
blocked.
- Around line 22-28: Current env vars SPRING_DATASOURCE_PASSWORD and
SPRING_DATASOURCE_USERNAME (and the app's JWT secret) are hardcoded; create a
Kubernetes Secret containing keys for the DB username, DB password, and JWT
secret, then update the Deployment env entries (SPRING_DATASOURCE_USERNAME,
SPRING_DATASOURCE_PASSWORD and the JWT env var used by the app) to use
valueFrom.secretKeyRef referencing that Secret; keep SPRING_DATASOURCE_URL as-is
or move it to the Secret if you prefer, and ensure the Secret key names match
the secretKeyRef names in the Deployment.
In `@pom.xml`:
- Around line 12-16: The POM currently pins the Spring Boot parent to an EOL,
vulnerable release (parent groupId/artifactId spring-boot-starter-parent with
version 3.2.0); update the parent version to a supported, patched release
(change the parent version element to either 4.0.2 or 3.5.10) to pull in
security fixes, then run a full build and tests and adjust any Java/tooling
compatibility (compiler source/target, spring-boot-maven-plugin configuration,
and dependency versions) if the upgrade surface requires it.
- Around line 54-71: Update the declared JJWT dependencies (jjwt-api, jjwt-impl,
jjwt-jackson) to 0.13.0 by changing the ${jjwt.version} property, and then
update any JWT handling code to accommodate breaking changes: replace usages of
Jwts.parserBuilder()/parser() with the new Jwts.parser() -> JwtParserBuilder
flow, treat Claims and Header as immutable (avoid mutating them), and handle
non-claims payloads as byte[] instead of String (adjust methods that read/write
payload accordingly). Also decide whether you will use Spring's Nimbus-based
validation (spring-boot-starter-oauth2-resource-server) or manual JJWT
validation; remove redundant JJWT runtime dependencies or document/encapsulate
the manual validation in a clearly named class (e.g., JwtService or
JwtValidator) to avoid conflicting validation paths.
In `@src/main/java/pl/piomin/services/config/SecurityConfig.java`:
- Around line 45-47: Remove the .oauth2ResourceServer(...) configuration from
SecurityConfig so the framework does not attempt to wire a second JWT processor;
instead rely on the existing JwtAuthenticationFilter you registered (ensure
JwtAuthenticationFilter is still added to the HttpSecurity filter chain as
before). Delete the oauth2ResourceServer(oauth2 ->
oauth2.jwt(Customizer.withDefaults())) block and any misleading H2-specific
authorize rule added for tests, leaving only the custom filter and your explicit
authentication/authorization rules in SecurityConfig.
In `@src/main/java/pl/piomin/services/controller/PersonController.java`:
- Around line 42-48: The controller is catching RuntimeException and converting
all unexpected errors into 404s; update PersonController to stop catching
generic RuntimeException around calls like personService.updatePerson(id,
personDetails) (and the similar block for delete at the other method) — either
remove the try/catch entirely so ResponseStatusException from the service can
propagate, or catch and map only a specific not-found exception (e.g.,
EntityNotFoundException) to ResponseEntity.notFound(), leaving all other
exceptions to bubble up; ensure you update both the updatePerson and
deletePerson try/catch blocks accordingly.
In `@src/main/java/pl/piomin/services/security/JwtAuthenticationFilter.java`:
- Around line 35-50: The call to jwtTokenProvider.validateToken(...) in
JwtAuthenticationFilter can throw RuntimeException for malformed/expired tokens;
wrap the validateToken call in a try-catch that catches RuntimeException (or
Exception), and on catch log/debug the token error and simply skip setting
authentication (do not rethrow) so the filter continues without authentication
and allows the security entry point to respond 401; ensure the rest of the
existing logic that calls jwtTokenProvider.getUsername(...),
userDetailsService.loadUserByUsername(...), builds
UsernamePasswordAuthenticationToken, sets details and calls
SecurityContextHolder.getContext().setAuthentication(...) only runs when
validateToken succeeds.
In `@src/main/java/pl/piomin/services/security/JwtTokenProvider.java`:
- Around line 53-70: The validateToken method in JwtTokenProvider currently
throws RuntimeException on JWT parsing errors instead of returning false; change
validateToken(String token) to catch the exceptions (MalformedJwtException,
ExpiredJwtException, UnsupportedJwtException, IllegalArgumentException), log the
specific error and then return false rather than rethrowing; add a private
static final Logger logger = LoggerFactory.getLogger(JwtTokenProvider.class) to
the class and use logger.error/.warn inside each catch to record the exception
message and context so callers relying on the boolean contract no longer receive
exceptions.
In `@src/main/java/pl/piomin/services/service/PersonService.java`:
- Around line 29-44: Replace the generic RuntimeException thrown in updatePerson
and deletePerson with a specific 404-capable exception: either throw new
ResponseStatusException(HttpStatus.NOT_FOUND, "Person not found with id: " + id)
from the PersonService.updatePerson and PersonService.deletePerson methods, or
create a PersonNotFoundException (extends RuntimeException) annotated with
`@ResponseStatus`(HttpStatus.NOT_FOUND) and throw that instead; update the throw
sites that currently call personRepository.findById(...).orElseThrow(...) so
they supply the new exception, and remove any controller try/catch that swallows
RuntimeException so normal Spring handling returns 404.
In `@src/main/resources/application.yml`:
- Around line 10-12: The YAML currently sets jpa.hibernate.ddl-auto: create-drop
which will drop and recreate all schema on each restart; change the
configuration so the default value is safer (e.g., set jpa.hibernate.ddl-auto:
update or validate) and move create-drop into a test-specific profile (e.g.,
application-test.yml or a spring.profiles block) so production/dev never uses
create-drop; update references to jpa.hibernate.ddl-auto in application.yml and
add/confirm a test profile containing create-drop for test runs.
- Around line 22-24: Replace the hardcoded app.jwt-secret value with an
environment-backed property and ensure the JWT signer reads it at runtime:
change the app.jwt-secret entry to reference an env var like ${APP_JWT_SECRET}
(no literal secret in source), and update the component that signs/verifies
tokens (look for usages of the app.jwt-secret property or classes named
JwtTokenProvider/JwtUtils) to fail fast or log a clear error if APP_JWT_SECRET
is unset; keep jwt-expiration-milliseconds as-is but ensure the runtime
configuration (Kubernetes/env) injects APP_JWT_SECRET into the deployment.
In `@src/test/java/pl/piomin/services/controller/PersonControllerTest.java`:
- Around line 75-88: The POST test createPerson_ValidPerson_ReturnsCreatedPerson
is missing a CSRF token and will fail under Spring Security; update the mockMvc
perform call(s) for all state-changing tests
(createPerson_ValidPerson_ReturnsCreatedPerson and any POST/PUT/DELETE tests) to
include a CSRF token by adding the SecurityMockMvcRequestPostProcessors.csrf()
request post-processor (i.e., call .with(csrf()) on the mockMvc.perform request)
and import
org.springframework.security.test.web.servlet.request.SecurityMockMvcRequestPostProcessors.csrf
so the requests are authorized during tests.
- Around line 23-24: The test class PersonControllerTest is annotated with
`@WebMvcTest` which enables Spring Security filters, causing 401 responses; fix by
adding authentication for tests—add `@WithMockUser` at the class level on
PersonControllerTest to provide a mock authenticated principal, or alternatively
disable security filters for the slice test by annotating PersonControllerTest
with `@AutoConfigureMockMvc`(addFilters = false) (choose one approach and update
the class annotations accordingly).

and either delete that entry or update the workflows to call the orb job name
"maven/test" (and map any required parameters) so the imported orb is actually
used.
- Around line 16-24: The CI currently runs three Maven phases separately (mvn
clean compile, mvn test, and mvn package -DskipTests) which redundantly
recompiles; replace the two pipeline steps ("Build and test" and "Package
application") with a single run that executes mvn clean package so Maven
compiles, runs tests, and packages in one pass (remove -DskipTests to ensure
tests execute).
In `@docker-compose.yml`:
- Around line 4-14: The docker-compose service "postgres" currently hardcodes
POSTGRES_USER and POSTGRES_PASSWORD environment variables; change this to load
credentials from a safer source by replacing the literal values with environment
variable references (e.g., ${POSTGRES_USER}, ${POSTGRES_PASSWORD}) or Docker
secrets, and add instructions to read them from a .env file or secret named
accordingly; update any documentation or examples to include a sample .env with
placeholders and ensure the compose file references the same variable names for
the postgres service and POSTGRES_DB to avoid committing plaintext credentials.
- Around line 21-22: The compose file uses depends_on which only orders startup
but not readiness; add a healthcheck to the postgres service (e.g., a
HEALTHCHECK that runs pg_isready or similar) and update the app service's
depends_on to wait for the postgres service to be healthy (use condition:
service_healthy) so the Spring Boot app does not attempt DB connections before
Postgres is ready; reference the postgres service name and the depends_on key to
locate where to add the healthcheck and condition.
In `@kubernetes/deployment.yaml`:
- Around line 17-19: The container "spring-boot-app" lacks resource
requests/limits; add a resources block under the container spec in the
Deployment manifest to set both requests and limits (cpu and memory) to prevent
unbounded usage and OOMs. Update the container named spring-boot-app by adding
resources.requests (e.g., cpu and memory baseline) and resources.limits (e.g.,
max cpu and memory) with appropriate values for your environment, and ensure the
Deployment/Pod spec includes these entries so the scheduler and kubelet enforce
them.
In `@kubernetes/ingress.yaml`:
- Around line 1-17: The Ingress manifest (metadata.name:
spring-boot-app-ingress) uses nginx-specific annotations but lacks an explicit
controller selection; add spec.ingressClassName: nginx to the Ingress spec so
the nginx controller picks it up (leave the existing
nginx.ingress.kubernetes.io/rewrite-target annotation intact); ensure you add
the spec.ingressClassName field alongside the existing spec block to explicitly
bind this Ingress to the nginx IngressClass.
In `@kubernetes/service.yaml`:
- Around line 7-14: The Service manifest currently sets spec.type: LoadBalancer
which is redundant when traffic is routed via an Ingress; edit the Service spec
(the block containing spec, selector: app: spring-boot-app, ports, and type) and
remove or change the line "type: LoadBalancer" to "type: ClusterIP" (or omit the
type to use the default ClusterIP) so the Ingress is the sole external entry
point and you avoid provisioning an extra cloud load balancer.
In `@README.md`:
- Around line 71-73: Add explicit language identifiers to the fenced code blocks
in README.md: change the block containing "Authorization: Bearer
<your-jwt-token>" to use a language like `http` or `text` and change the project
structure/example block starting with "claude-ai-spring-boot/" (lines ~95-137)
to use `text`; update each opening triple-backtick to include the language token
(e.g., ```http or ```text) so the fenced blocks with "Authorization: Bearer
<your-jwt-token>" and the "claude-ai-spring-boot/" listing comply with
markdownlint MD040.
In `@skaffold.yaml`:
- Around line 19-25: The dev profile duplicates the top-level build.local.push:
false setting; remove the redundant entry under the "profiles" -> "- name: dev"
-> "build.local.push" so the profile no longer re-declares push: false (keep the
profile if you need activation by kubeContext: minikube, but delete the nested
push key or the entire build.local block inside the dev profile to avoid
duplication).
- Line 1: The skaffold manifest uses an outdated API version; update the
apiVersion value "skaffold/v2beta4" to the current supported version
"skaffold/v4beta13" (i.e., replace the string literal in the skaffold.yaml file)
so the manifest is compatible with recent Skaffold CLI releases and enables
newer features.
In `@src/main/java/pl/piomin/services/controller/AuthController.java`:
- Line 37: Remove the unnecessary update to the security context: delete the
call SecurityContextHolder.getContext().setAuthentication(authentication) in
AuthController (the code path that generates and returns the token) because the
app uses SessionCreationPolicy.STATELESS and the context is not persisted;
simply generate/return the token without setting the SecurityContextHolder.
- Around line 47-67: Replace the verbose inner DTO class LoginRequest in
AuthController with a Java record to remove boilerplate getters/setters;
specifically, change the nested public static class LoginRequest { ... } to a
public record LoginRequest(String username, String password) and ensure any
references in methods like the controller's login handler accept the record type
(Jackson on Java 17 will deserialize it automatically). Also remove unused
setter/getter usages and imports related to the old class.
In `@src/main/java/pl/piomin/services/security/CustomUserDetailsService.java`:
- Around line 18-24: The users returned in CustomUserDetailsService are created
with empty authorities, so role-based checks will fail; update the User creation
in the loadUserByUsername method to supply appropriate GrantedAuthority lists
(e.g., use SimpleGrantedAuthority instances such as "ROLE_USER" for the "user"
account and "ROLE_ADMIN" (and optionally "ROLE_USER") for the "admin" account)
instead of new ArrayList<>() so security expressions like hasRole("ADMIN") work
correctly.
In `@src/main/java/pl/piomin/services/security/JwtTokenProvider.java`:
- Line 28: JwtTokenProvider currently calls
Keys.hmacShaKeyFor(jwtSecret.getBytes()) (and repeats this on other methods),
which uses the platform default charset and re-derives the SecretKey on every
call; fix by creating a single cached SecretKey field (e.g., private final
SecretKey jwtKey) initialized once (constructor or `@PostConstruct`) using
Keys.hmacShaKeyFor(jwtSecret.getBytes(StandardCharsets.UTF_8)) and update all
usages (the spots calling Keys.hmacShaKeyFor or jwtSecret.getBytes() —
referenced in JwtTokenProvider and the methods around the other occurrences) to
use the cached jwtKey instead of re-creating it.
In `@src/main/java/pl/piomin/services/service/PersonService.java`:
- Around line 14-15: Replace field injection of personRepository in
PersonService with constructor injection: remove the `@Autowired` annotation on
the private PersonRepository personRepository field and add a constructor (e.g.,
public PersonService(PersonRepository personRepository)) that assigns the
parameter to the field; annotate the constructor with `@Autowired` only if not
using recent Spring versions that infer it, or simply use a single public
constructor so Spring can inject the dependency. Ensure PersonService uses the
injected personRepository field everywhere.
In `@src/main/resources/application.yml`:
- Around line 26-29: Change the default logging level for Spring Security from
DEBUG to a non-sensitive level (e.g., INFO or WARN) by updating the
logging.level key for org.springframework.security to INFO/WARN; keep
pl.piomin.services as needed. Also move DEBUG for org.springframework.security
into a development-only profile (e.g., application-dev.yml or a Spring profile
block) so DEBUG is enabled only when the dev profile is active. Update the
logging.level entry for org.springframework.security and add a dev-profile
override to enable DEBUG during development.
- Around line 6-8: The DB credentials (url, username, password) are hardcoded in
application.yml; replace them with environment-backed placeholders so secrets
aren’t stored in repo. In application.yml change the url/username/password
entries to use Spring property placeholders like
${DB_URL:jdbc:postgresql://localhost:5432/persondb}, ${DB_USER:postgres},
${DB_PASS:postgres} (or your chosen names) so local defaults remain but
non-local deployments can inject real values via environment/K8s; ensure any
code/config that references these keys still uses the same property names.

openjdk Docker image deprecated official status
💡 Result:
The Docker Official Image openjdk (i.e., docker.io/library/openjdk, shown on Docker Hub as openjdk) has an explicit “DEPRECATION NOTICE”: it is officially deprecated, and users are told to migrate to other Java “Official Image” alternatives such as eclipse-temurin, amazoncorretto, ibm-semeru-runtimes, ibmjava, or sapmachine.[1] Docker notes that only Early Access (EA) tags would continue receiving updates beyond July 2022 (sourced from jdk.java.net).[1]
The underlying driver is explained in the linked upstream discussion: Red Hat announced it would retire the “OpenJDK Project Builds” for JDK 8u and 11u after the July 2022 CPU update, which were used for openjdk:8 and openjdk:11, and suggested removing those tags later (e.g., October 2022) to avoid users relying on out-of-date builds.[2]

eclipse-temurin:17-jre-alpine availability compatibility
💡 Result:
Availability (Docker Official Image)
eclipse-temurin:17-jre-alpineexists and is published on Docker Hub as part of the officialeclipse-temurinimage set. (stackoverflow.com)- The
eclipse-temurinofficial images are multi-architecture (includingamd64,arm32v7,arm64v8,ppc64le,riscv64,s390x, andwindows-amd64; Alpine variants are Linux-only). (hub.docker.com) - As of the July 23, 2025 Temurin release announcement, the default Alpine base for Temurin images moved to Alpine 3.22, and older Alpine bases remain available via a suffix like
-alpine-3.21. (adoptium.net)
Compatibility considerations (why “alpine” can break)
- The
*-alpinevariants use musl libc, not glibc. This is the#1compatibility difference and can break software that relies on glibc assumptions—most commonly:- native JNI/JNA libraries shipped as
linux-x86_64binaries built against glibc - agents/profilers and vendor SDKs that bundle native code (hub.docker.com)
- native JNI/JNA libraries shipped as
- Temurin 17 specifically introduced musl-targeted builds (so the JVM itself is fine on Alpine), but your app’s dependencies may still be the problem. (adoptium.net)
Practical guidance
- If you depend on native libraries and want maximum compatibility, prefer a glibc-based tag such as
eclipse-temurin:17-jre(Ubuntu-based by default) or UBI variants, instead of*-alpine. (hub.docker.com) - If you stay on Alpine, validate all native dependencies are musl-compatible (or provide musl builds). (hub.docker.com)

Trivy flagged DS-0002: the container runs as root by default, which violates the principle of least privilege. Additionally, the openjdk Docker Official Image is explicitly deprecated with no updates beyond Early Access tags (post-July 2022). Eclipse Temurin is the official recommended replacement.

💡 Result:
-
Spring Boot 3.2.0 is not “latest” (it was released Nov 23, 2023) and the 3.2 line’s OSS support ended Dec 31, 2024. Staying on 3.2.0 means you will miss later community security fixes unless you have commercial/3rd‑party backports. [1][2]

Latest 3.5.x: 3.5.10 (also Jan 22, 2026 on Maven Central). [4]
Security/CVE notes relevant to Spring Boot 3.2.0
- CVE-2024-38807 (Spring Boot Loader signature forgery) — fixed in Spring Boot 3.2.9 (and 3.3.3). [5]
- CVE-2025-22235 (Actuator
EndpointRequest.to()can create an incorrect matcher like/null/**when endpoint disabled/not exposed) — affects 3.2.0 up to < 3.2.14. Since the open-source 3.2 line ended earlier, the practical fix is to upgrade to a supported Boot line (or use a commercial/3rd-party patched build).

What to do
- If you need current security patches, upgrade off 3.2.0 to a supported line, typically 4.0.2 (current stable) or 3.5.10 if you must stay on Spring Boot 3.x. [3][4]

🛠️ Refactor suggestion | 🟠 Major
Throwing generic RuntimeException weakens error handling.
Both updatePerson and deletePerson throw a bare RuntimeException for not-found cases. The controller then catches RuntimeException — which is overly broad and will silently swallow unrelated errors (e.g., database connectivity issues, constraint violations) as 404s.
Consider using a dedicated exception (or Spring's ResponseStatusException):
Suggested approach
-import java.util.List;
-import java.util.Optional;
+import java.util.List;
+import java.util.Optional;
+import org.springframework.web.server.ResponseStatusException;
+import org.springframework.http.HttpStatus;
...
Person person = personRepository.findById(id)
- .orElseThrow(() -> new RuntimeException("Person not found with id: " + id));
+ .orElseThrow(() -> new ResponseStatusException(HttpStatus.NOT_FOUND, "Person not found with id: " + id));This eliminates the need for try-catch blocks in the controller entirely.

- 44, Replace the generic RuntimeException thrown in updatePerson and
deletePerson with a specific 404-capable exception: either throw new
ResponseStatusException(HttpStatus.NOT_FOUND, "Person not found with id: " + id)
from the PersonService.updatePerson and PersonService.deletePerson methods, or
create a PersonNotFoundException (extends RuntimeException) annotated with
`@ResponseStatus`(HttpStatus.NOT_FOUND) and throw that instead; update the throw
sites that currently call personRepository.findById(...).orElseThrow(...) so
they supply the new exception, and remove any controller try/catch that swallows
RuntimeException so normal Spring handling returns 404.

ddl-auto: create-drop will destroy all data on every application restart.
This is extremely dangerous if the application is ever run against a real database. It drops and recreates all tables on shutdown/startup. Consider using update or validate as the default, and reserving create-drop for a test profile.

Hardcoded JWT signing secret is a security risk.
The JWT secret is a static, easily guessable string committed to version control. Anyone with access to the repo can forge valid tokens. This should be externalized (e.g., via an environment variable ${APP_JWT_SECRET}) and injected at runtime, especially since the Kubernetes deployment already overrides datasource properties via env vars but not the JWT secret.

Tests will fail with 401 — Spring Security filters are active but no authentication is provided.
@WebMvcTest auto-configures Spring Security when it's on the classpath. Since no mock user or security bypass is configured, every request will receive a 401 Unauthorized response, causing all assertions to fail.
The simplest fix is to add @WithMockUser at the class level, or import a permissive security configuration for tests:
Option 1: Add `@WithMockUser` (simplest)
+import org.springframework.security.test.context.support.WithMockUser;
+
`@WebMvcTest`(PersonController.class)

POST test may also fail due to missing CSRF token.
With Spring Security active, state-changing requests (POST, PUT, DELETE) require a CSRF token by default. Even with @WithMockUser, you'll need to include CSRF in the request:
mockMvc.perform(post("/api/persons")
.with(csrf())
.contentType(MediaType.APPLICATION_JSON)
.content(objectMapper.writeValueAsString(person)))This applies to all POST, PUT, and DELETE test methods. Import org.springframework.security.test.web.servlet.request.SecurityMockMvcRequestPostProcessors.csrf.
