集成Spring JPA,在执行delete,update时需要添加事务。
错误信息:
org.springframework.dao.InvalidDataAccessApiUsageException: Executing an update/delete query; nested exception is javax.persistence.TransactionRequiredException: Executing an update/delete query

解决:通过添加注解@Transactional
@Transactional
@Modifying
@Query(value = "update User user set user.address = :address where user.id = :id ")
void updateUserAddress(@Param("id") int id,@Param("address") String address);
注意,添加的是import org.springframework.transaction.annotation.Transactional。
