SpringBoot-JPA删除不成功，只执行了查询语句

标签：tran   lock   sel   语句   from   删除   spring   查询语句   where   

今天使用JPA自定义了一个删除方法deleteByUserIdAndCommentId发现并没有删除掉对应的数据，只执行了查询语句

Hibernate: select good0_.id as id1_6_, good0_.commentId as commenti2_6_, good0_.userId as userid3_6_ from tbl_good good0_ where good0_.userId=? and good0_.commentId=?

解决方法：

在删除方法前加注解@Transactional即可

再次执行时会正常执行

Hibernate: select good0_.id as id1_6_, good0_.commentId as commenti2_6_, good0_.userId as userid3_6_ from tbl_good good0_ where good0_.userId=? and good0_.commentId=?
Hibernate: delete from tbl_good where id=?
Hibernate: select comment0_.id as id1_3_0_, comment0_.articleId as articlei2_3_0_, comment0_.ccomment as ccomment3_3_0_, comment0_.goodNum as goodnum4_3_0_, comment0_.userId as userid5_3_0_, comment0_.userType as usertype6_3_0_ from tbl_comment comment0_ where comment0_.id=?
