保存对象时未填充Spring Boot JPA @ CreatedDate @LastModifiedDate

我正在使用Postgres数据库使用Spring Boot + JPA编写应用程序。我有一个用户实体,正在尝试获取保存和/或修改用户记录时的时间戳。这是行不通的。保存的记录的createdDate和lastModifiedDate都为“ null”。

以下是Kotlin中的所有相关代码:

@Entity
@Table(name = "app_user")
@EntityListeners(AuditingEntityListener::class)
data class User(
        @Id
        @GeneratedValue(strategy = GenerationType.AUTO)
        @Column(name = "id")
        val id: UUID? = null,

        @NotNull
        @Column(unique = true)
        val email: String,
        val name: String,
        private val password: String,

        @CreatedDate
        @Column(name = "created_date", nullable = false, updatable = false)
        var createdDate: LocalDateTime? = null,

        @LastModifiedDate
        @Column(name = "last_modified_date", nullable = false)
        var lastModifiedDate: LocalDateTime? = null
)

我添加日期字段的SQL查询如下:

ALTER TABLE app_user
ADD COLUMN last_modified_date TIMESTAMP,
ADD COLUMN created_date TIMESTAMP;

我也有一个配置类

@Configuration
@EnableJpaAuditing(auditorAwareRef = "auditorProvider")
class JpaAuditingConfiguration {

    @Bean
    fun auditorProvider(): AuditorAware<String> {
        return AuditorAware { Optional.of(SecurityContextHolder.getContext().authentication.name) }
    }

}

我的考试班:

  @Autowired
    private lateinit var userRepository: UserRepository

    val user = User(
            email = "email",
            name = "name",
            password = "password"
    )

    @Test
    fun `it sets the timestamps when a user is created`() {
        userRepository.save(user)
        user.let {
            assertThat(it.createdDate).isNotNull()
            assertThat(it.lastModifiedDate).isNotNull()
        }
    }

更新:

似乎问题仅在测试中发生。当我在开发环境而不是测试中执行相同的代码来创建用户时,这似乎很好。

测试中是否需要其他配置?

更新2

我还尝试过这样使用实体管理器:

@Autowired
lateinit var entityManager: TestEntityManager

然后在测试中执行

entityManager.persist(user)
entityManager.flush()

还有

entityManager.persistAndFlush(user)

仍然没有填充时间戳。

@PrePersist@PreUpdate阶段调用AuditingEntityListener方法。

这意味着它们将在执行插入或更新SQL语句之前被调用。

在Hibernate文档中了解有关JPA事件的更多信息: https://docs.jboss.org/hibernate/orm/5.2/userguide/html_single/Hibernate_User_Guide.html#events-jpa-callbacks

单元测试

在“测试”中使用时,您还必须在测试中启用审核

@DataJpaTest
@RunWith(SpringRunner.class)
@EnableJpaAuditing
public class EntityListenerTest {

我的首选解决方案是一组多个注释,以确保测试@CreatedBy@CreatedDate

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

我的实体看起来像:

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

    @CreatedBy
    private String createdBy;

    @CreatedDate
    private Date createdOn;

    @LastModifiedDate
    private Date updatedOn;

    @LastModifiedBy
    private String updatedBy;
}

我的JPA配置是:

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

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

现在,您的审核字段也在JPA测试期间创建:

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

我遇到了类似的问题(Spring Boot 2.2.1和JUnit5),其值为null。将@EnableJpaAuditing添加到测试类无法正常工作。

我的示例(未复制所有内容):

@Getter(AccessLevel.PROTECTED)
@Setter(AccessLevel.PROTECTED)
@MappedSuperclass
@EntityListeners(AuditingEntityListener.class)
public class Auditable<U> {

    @CreatedBy
    @Column(name = "created_by", nullable = false)
    private U createdBy;

    @CreatedDate
    @Column(name = "created", nullable = false)
    private OffsetDateTime created;
}

和相应的班级:

@Getter
@Setter
@Entity
@Table(name="survey_records")
public class SurveyRecord extends Auditable<String> implements Serializable {

我具有以下用于审核的配置:

@Configuration
@EnableJpaAuditing(auditorAwareRef = "auditorProvider", dateTimeProviderRef = "auditingDateTimeProvider")
public class JpaAuditingConfiguration {

    @Bean(name = "auditingDateTimeProvider")
    public DateTimeProvider dateTimeProvider() {
        return () -> Optional.of(OffsetDateTime.now());
    }

    @Bean
    public AuditorAware<String> auditorProvider() {

要让@CreatedBy@CreatedDate在内部测试中工作,只需要@Import

@DataJpaTest
@Import(JpaAuditingConfiguration.class)
class SurveyRecordRepositoryTest {

我有类似的问题,但是我的情况是因为我在测试类上有@Transactional批注,删除后,一切按预期进行。
