Spring Boot JPA transaction not rolling back on handling in @Transactional method
I'm learning this framework and Hey everyone, I'm running into an issue that's driving me crazy. I'm sure I'm missing something obvious here, but I'm working with an scenario with my Spring Boot application where exceptions thrown in a method annotated with `@Transactional` are not causing the transaction to roll back as expected. I'm using Spring Boot 2.6.4 and Hibernate 5.6.3.Final. The method is supposed to save an entity and throw an exception if a validation fails, but the changes are being persisted even after the exception is thrown. Here’s the relevant code snippet: ```java @Service public class MyService { @Autowired private MyRepository myRepository; @Transactional public void saveEntity(MyEntity entity) { if (entity.getName() == null) { throw new IllegalArgumentException("Name want to be null"); // This should trigger a rollback } myRepository.save(entity); } } ``` The repository looks like this: ```java @Repository public interface MyRepository extends JpaRepository<MyEntity, Long> { } ``` When I call `saveEntity` with an entity that has a null name, the exception is thrown as expected, but the transaction still commits and the entity is saved to the database. I've tried setting `rollbackFor = Exception.class` in the `@Transactional` annotation, but it hasn't helped either. Here’s how I’m calling the service method: ```java @RestController @RequestMapping("/api") public class MyController { @Autowired private MyService myService; @PostMapping("/entities") public ResponseEntity<Void> createEntity(@RequestBody MyEntity entity) { myService.saveEntity(entity); return ResponseEntity.ok().build(); } } ``` I also checked my transaction manager configuration, and I'm using the default `JpaTransactionManager`. Is there something that I'm missing in terms of Spring transaction management, or is there a potential configuration scenario? Any insights would be appreciated! My development environment is Ubuntu. Thanks in advance! I'm working with Java in a Docker container on Ubuntu 22.04. Any feedback is welcome!
