Spring JPA 使用@transaction注解时产生CGLIB代理冲突的解决方法
来源:互联网 发布:资治通鉴和史记 知乎 编辑:程序博客网 时间:2024/05/29 05:09
在使用JPA进行数据库的删除操作时需要使用@Transactional注解来支持事物:
@Modifying @Transactional @Query(" delete from FollowerInfo " + " where crmAuth = :crmAuth and investUserId = :invUserId") void deleteByCrmAuthAndInvUserId(@Param("crmAuth") String crmAuth, @Param("invUserId") Long invUserId);
但是,在添加了如上方法后,测试服务启动失败。查看日志报错如下:

对于此异常,这篇帖子中讲到了产生该异常的原因,但是未给出解决办法。

简单来说,原因主要是代理冲突:Spring 早期的版本,要用com.sun.proxy的代理 ,而 jpa如果加了@transaction 注解后 需要用CGLIB的代理
因此产生了冲突
解决办法:
Spring 已经在高版本中修复了该问题,把Spring从4.0升级到4.2.5后,问题解决:
在pom.xml加入:
<properties> <spring.framework.version>4.2.5.RELEASE</spring.framework.version> </properties>
