Spring JPA 使用@transaction注解时产生CGLIB代理冲突
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：
|
1 2 3 4 5 |
@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。
http://stackoverflow测试数据/questions/20063320/springmvc-proxy-issue
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：
|
1 2 3 |
< properties > < spring.framework.version >4.2.5.RELEASE</ spring.framework.version > </ properties > |
Spring 启用CGLIB解决事物代理失败
问题描述：
接口A提供公用的CRUD 操作，抽象类B实现接口A，接口C提供各模型特有的相关数据库操作。
类D继承抽象类B实现接口C如果使用JDK动态代理，Spring会将类D向上转型为接口C，那么在使用中必须注入接口A。
如果注入类D的类型。会报错说代理类型XX无法转换为类D的类型。
解决办法如下：

< bean id = "transactionManagerCMS" class = "org.springframework.orm.hibernate4.HibernateTransactionManager" > < property name = "sessionFactory" ref = "mySessionFactory" /> < property name = "dataSource" ref = "dataSourceCMS" /> </ bean > <!-- the transactional advice (what 'happens'; see the <aop:advisor/> bean below) --> < tx:advice id = "txAdvice" transaction-manager = "transactionManagerCMS" > <!-- the transactional semantics... --> < tx:attributes > < tx:method name = "*" /> </ tx:attributes > </ tx:advice > <!-- ensure that the above transactional advice runs for any execution of an operation defined by the FooService interface --> < aop:config proxy-target-class = "true" > < aop:pointcut id = "fooServiceOperation" expression = "execution(* com.harvest.smartHotels.info.dao.serviceContent.interfaces.*.*(..))" /> < aop:advisor advice-ref = "txAdvice" pointcut-ref = "fooServiceOperation" /> </ aop:config > |
动态代理使用CGLIB，这样注入类型就可以使类D。
