【JPA】@Modifying使用的问题

控制台错误日志：

Caused by: javax.persistence.TransactionRequiredException: Executing an update/delete query

 

DAO层：

    @Modifying
    @Query(nativeQuery = true, value = "DELETE FROM user t WHERE t.user_name= ?1 AND t.user_id = ?2")
    void deleteByUserNameAndUserId(String userName, String userId);

　　

Service层：

public Optional<String> deleteUser(String userName, String userId) {
        userRepository.deleteByUserNameAndUserId(userKey, type); 
　　　　  // 省略其它业务逻辑 
}

 

解决方法：

在DAO层方法上添加@Transactional

    @Modifying
    @Transactional
    @Query(nativeQuery = true, value = "DELETE FROM user t WHERE t.user_name= ?1 AND t.user_id = ?2")
    void deleteByUserNameAndUserId(String userName, String userId);
