[英]org.springframework.dao.DataIntegrityViolationException after update spring-boot from 2.1.x to 2.2.x using hibernate and spring-boot-data-jpa
When trying to update spring-boot from version 2.1.12 to 2.2.4 got stuck on DataIntegrityViolationException when try to insert multiple objects into MySQL using JPA.尝试将 spring-boot 从版本 2.1.12 更新到 2.2.4 时,在尝试使用 JPA 将多个对象插入 MySQL 时卡在 DataIntegrityViolationException 上。
Example object:示例对象:
@Data
@Entity
@AllArgsConstructor
@NoArgsConstructor
@Builder(toBuilder = true)
@Table(name = "user")public class User {
@Id
@Column(name = "id")
@JsonProperty("id")
private String id;
@PrimaryKeyJoinColumn
@OneToOne(cascade = CascadeType.ALL)
@JsonProperty("status")
private UserStatus status;
}
And user status:和用户状态:
@Data
@Entity
@AllArgsConstructor
@NoArgsConstructor
@Table(name = "user_status")
public class UserStatus {
@Id
@Column(name = "id")
@JsonProperty("id")
private String id;
public UserStatus(String userId) {
this.id = userId;
}
}
To insert object to mysql I use default jpa repository:要将对象插入 mysql,我使用默认的 jpa 存储库:
@Repository
public interface UserRepository extends JpaRepository<User, String> {
}
With spring-boot-2.1.x userRepository.save(user)
works fine but with 2.2.x it raises this exception:使用 spring-boot-2.1.x
userRepository.save(user)
工作正常,但使用 2.2.x 会引发此异常:
org.springframework.dao.DataIntegrityViolationException: could not execute statement; SQL [n/a]; constraint [null]; nested exception is org.hibernate.exception.ConstraintViolationException: could not execute statement
With this details in log:在日志中包含此详细信息:
Cannot add or update a child row: a foreign key constraint fails (`test`.`user_status`, CONSTRAINT `user_status_ibfk_1` FOREIGN KEY (`id`) REFERENCES `user` (`id`) ON DELETE CASCADE)
If enable spring.jpa.show-SQL: true
I found out that with spring-boot-2.2.x no insertion on User
entity is happening but with old spring it is.如果启用
spring.jpa.show-SQL: true
我发现使用 spring-boot-2.2.x 没有插入User
实体,但使用旧的 spring。
I didn't find any major change in spring-boot connecting to hibernate as well as no major change in hibernate itself after the corresponding update.我没有发现 spring-boot 连接到 hibernate 有任何重大变化,相应更新后 hibernate 本身也没有重大变化。 Is there anything updated which is not described in release notes?
是否有发行说明中未描述的更新内容?
spring-boot 2.1.12 uses Hibernate 5.3.15.Final and spring-boot 2.2.4 uses Hibernate 5.4.10.Final spring-boot 2.1.12 使用 Hibernate 5.3.15.Final 和 spring-boot 2.2.4 使用 Hibernate 5.4.10.Final
Your issue seems similar to Hibernate issues HHH-13413 HHH-13171您的问题似乎类似于 Hibernate 问题HHH-13413 HHH-13171
The reason is in the fix HHH-12436 which was introduced in 5.4.0.CR1 so since then one-to-one mappings don't work when @OneToOne(mappedBy ="") didn't provided.原因是在5.4.0.CR1中引入的修复HHH-12436 中,因此当 @OneToOne(mappedBy ="") 未提供时,一对一映射不起作用。
And as I understood from disscussions in JIRA it's not a bug now.正如我从 JIRA 中的讨论中了解到的,它现在不是一个错误。 There was a bug and they fixed it like so.
有一个错误,他们像这样修复了它。 I guess there is some misunderstanding with
@PrimaryKeyJoinColumn
so people doesn't use it right.我猜对
@PrimaryKeyJoinColumn
有一些误解,所以人们没有正确使用它。
I guess this will solve the problem我想这将解决问题
@OneToOne(mappedBy = "user", cascade = CascadeType.ALL)
@JsonProperty("status")
private UserStatus status;
