Spring Boot JPA@CreatedDate @LastModifiedDate not being populated when saving the object

Question

I am writing an app with Spring Boot + JPA, using a Postgres database. I have a User Entity and I am trying to get a timestamp when the user record is saved and/or modified.

Answer 1

My prefered solution is a set of multiple annotations to ensure test of @CreatedBy or @CreatedDate:

@RunWith(SpringRunner.class)
@DataJpaTest
@Import(JPAConfig.class)
@WithMockUser(username = "testuser")
public class MYRepositoryTest {
...
}

My Entities looks like:

@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public class AbstractEntity {

    @CreatedBy
    private String createdBy;

    @CreatedDate
    private Date createdOn;

    @LastModifiedDate
    private Date updatedOn;

    @LastModifiedBy
    private String updatedBy;
}

My JPA configuration is:

@Configuration
@EnableJpaAuditing(auditorAwareRef = "auditorAware")
public class JPAConfig {

    @Bean
    public AuditorAware auditorAware() {
        return () -> Optional.of(((User)     SecurityContextHolder.getContext().getAuthentication().getPrincipal()).getUsername());
    }
}

Now your audit fields also created during JPA test:

assertThat(result.getCreatedBy()).isNotNull().isEqualTo("testuser");
assertThat(result.getCreatedOn()).isNotNull();
assertThat(result.getUpdatedBy()).isNotNull().isEqualTo("testuser");
assertThat(result.getUpdatedOn()).isNotNull();
