feat: upgrade to Spring Boot 4.0 and JDK 25 LTS #234
Conversation
- Upgrade Spring Boot from 3.4.4 to 4.0.0 - Upgrade JDK from 21 to 25 (LTS) - Migrate spring-boot-starter-web to spring-boot-starter-webmvc - Add modular test starters (webmvc-test, data-jpa-test, cache-test) - Update @WebMvcTest import to org.springframework.boot.webmvc.test.autoconfigure - Update @DataJpaTest import to org.springframework.boot.data.jpa.test.autoconfigure - Add @AutoConfigureCache to slice tests for CacheManager support - Update Docker images to eclipse-temurin:25-jdk/jre-alpine - Update GitHub Actions to use JDK 25
WalkthroughA framework upgrade from Spring Boot 3/JDK 21 to Spring Boot 4/JDK 25, encompassing updates to the parent pom, dependencies (including webmvc and cache starters), base Docker images, CI/CD workflows, documentation, and test annotations. Changes

src/test/java/ar/com/nanotaboada/java/samples/spring/boot/test/repositories/BooksRepositoryTests.java (1)
3-5: Prefer AssertJ over JUnit assertions in repository testsGiven AssertJ is already in use, you can drop the JUnit
assertTruein favor of an AssertJ assertion for consistency with the testing guidelines.A possible refactor:
-import static org.junit.jupiter.api.Assertions.assertTrue; @@ - Optional<Book> actual = repository.findByIsbn(existing.getIsbn()); - // Assert - assertTrue(actual.isPresent()); - assertThat(actual.get()).usingRecursiveComparison().isEqualTo(existing); + Optional<Book> actual = repository.findByIsbn(existing.getIsbn()); + // Assert + assertThat(actual).isPresent(); + assertThat(actual.get()).usingRecursiveComparison().isEqualTo(existing);This keeps all assertions in AssertJ and allows you to remove the unused JUnit static import. As per coding guidelines, AssertJ is preferred for fluent assertions in tests.

140-141: Add Mockito/ByteBuddy compatibility troubleshooting to the Troubleshooting section.If Spring Boot 4.0.0 requires Mockito agent configuration for JDK 25, document this in the Troubleshooting section. Consider adding:
### Build Failures + - **Mockito/ByteBuddy errors in tests**: JDK 25 may require explicit Mockito agent configuration. Add argLine with Mockito agent to maven-surefire-plugin if tests fail with ByteBuddy errorsAlso applies to: 209-209

src/test/java/ar/com/nanotaboada/java/samples/spring/boot/test/controllers/BooksControllerTests.java (3)
16-23: New WebMvc/cache test imports look consistent with Spring Boot 4 slicesThe switch to
org.springframework.boot.webmvc.test.autoconfigure.WebMvcTest,org.springframework.boot.cache.test.autoconfigure.AutoConfigureCache, andorg.springframework.test.context.bean.override.mockito.MockitoBeanmatches the modular test starters described in the PR and looks coherent for Boot 4 slice tests.Please just confirm that the corresponding WebMvc/cache/Mockito test starters are on the classpath and that the whole test suite passes under JDK 25.
37-39: Class-level@AutoConfigureCacheis a good fit for this WebMvc sliceEnabling
@AutoConfigureCacheat the controller slice level makes sense given the cache-test starter and keeps cache configuration aligned with how the app is wired.Verify that this does not accidentally pull in any unwanted cache infrastructure for WebMvc tests (e.g., if you later add multiple cache managers).
46-50: Confirm@MockitoBeanis the new project standard for controller mocksUsing
@MockitoBeanforBooksServiceandBooksRepositoryin this WebMvc test should continue to provide Mockito-based mocks, but it does change semantics compared to the older@MockBeanapproach referenced in the current guidelines.Given the existing guidance to use
@MockBeanin tests, please confirm that:
- The team intends to standardize on
@MockitoBeanfor Spring Boot 4, and- Project documentation/guidelines are updated accordingly so future tests follow the same pattern.
Based on learnings, the guidelines still mention@MockBean, so aligning them with this change will avoid confusion.src/test/java/ar/com/nanotaboada/java/samples/spring/boot/test/repositories/BooksRepositoryTests.java (2)
12-14: Updated JPA test and cache imports match Spring Boot 4 test configurationUsing
org.springframework.boot.data.jpa.test.autoconfigure.DataJpaTesttogether withorg.springframework.boot.cache.test.autoconfigure.AutoConfigureCacheis consistent with the Boot 4 modular test setup and the cache-test starter added in this PR.Please confirm that the new
data-jpa-testandcache-teststarters are present in the build so these imports resolve cleanly under JDK 25.
19-22:@AutoConfigureCacheon repository slice keeps cache behavior consistentAdding
@AutoConfigureCachetoBooksRepositoryTestsmirrors the controller tests and should ensure repository-level behavior is tested with the same cache configuration.Double-check that this doesn’t unintentionally mask cache-related issues (e.g., if production config differs from the default cache auto-config) and that it aligns with how you expect repositories to be cached in the app.
.github/workflows/maven.yml (1)
16-16: Consider adding explicit Mockito agent configuration for JDK 25 tests.Starting with Java 21, Maven's Surefire plugin should be configured to load the Mockito agent explicitly to ensure test compatibility with newer Java versions. If test failures occur related to Mockito/ByteBuddy, add Mockito agent configuration to the Maven Surefire plugin in
pom.xml.Monitor the test runs in this workflow to detect any Mockito-related failures. If tests fail with ByteBuddy errors, apply this configuration to
pom.xml:<plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-surefire-plugin</artifactId> <configuration> <argLine>-javaagent:${settings.localRepository}/org/mockito/mockito-core/${mockito.version}/mockito-core-${mockito.version}.jar</argLine> </configuration> </plugin>Dockerfile (1)
5-5: Docker base images correctly updated to JDK 25.Multi-stage build with Eclipse Temurin Alpine images follows best practices. Base image updates from JDK 21 to 25 are consistent across builder and runtime stages.
Also applies to: 22-22
README.md (1)
10-10: Documentation accurately reflects Spring Boot 4 and JDK 25 upgrade.All prerequisite and setup instructions have been updated consistently to target JDK 25. Test structure documentation now mentions
@AutoConfigureCacheand@MockitoBean, aligning with Spring Boot 4.0's modular test starters.Also applies to: 29-29, 69-69, 77-77
.github/copilot-instructions.md (1)
92-92: Remove or qualify the JDK 25 feature recommendation pending Mockito compatibility verification.Line 92 recommends leveraging JDK 25 features, but the retrieved learnings explicitly warn against using JDK 22+ due to Mockito/ByteBuddy compatibility issues. Update this guidance to conditional based on the outcome of the JDK 25 / Mockito compatibility verification.
Suggested update:
- **Modern Java**: Leverage JDK 25 features (records, pattern matching, sealed classes, etc.) where beneficial + **Modern Java**: Leverage JDK 25 features where beneficial; note JDK 25/Mockito compatibility (see Troubleshooting section)pom.xml (2)
9-18: Approve Spring Boot 4.0.0 upgrade structure and modular dependency organization.The migration from Spring Boot 3.4.4 to 4.0.0 is well-executed with proper modular starter structure (webmvc, cache, data-jpa) and corresponding test starters. Comments documenting each section and linking to Maven Repository are helpful for future maintenance.
16-16: Spring Boot 4.0.0 already manages compatible Byte Buddy and Mockito versions for Java 25—no override needed.Spring Boot 4.0.0 declares first-class support for Java 25 and transitively manages Byte Buddy 1.17.8 and Mockito 5.20.0, both of which support Java 25 without issues. No explicit dependency override is required.
.java-version (1)
1-1: No action required—JDK 25 is fully supported.Spring Boot 4.0.0 explicitly supports JDK 25 and includes compatible Mockito/ByteBuddy versions in its dependency management. The upgrade is valid and requires no changes.
