使用

@PersistenceContext

时出现异常如果您使用的是运行在

Tomcat

上的

EclipseLink和JOTM

，那么在persistence.xml中，我猜您忘记了

属性

：

    <properties>

        <property name="eclipselink.target-server" value="org.eclipse.persistence.transaction.jotm.JotmTransactionController"/>

    </properties>

stacktrace中没有关于事务的内容，因此它们未启用。确保您的服务上有

@Transactional

。@M.Deinum-当我对服务类使用

@Transactional

时，启动tomcat时会出现异常。请参阅我的编辑部分。我猜您的

PersonDao

实现了接口，或者由于您的设置，您正在代理一个代理。@M.Deinum-感谢您的回复

PersonDao

正在扩展另一个名为

GenericDao

的类。我无法代理代理

。我使用基于类的代理（@EnableTransactionManagement（proxyTargetClass=true））来避免不必要的接口。我需要对配置进行任何更改吗？使用基于类的代理并不意味着不能代理代理。。。此外，如果它实现任何接口，它可能会中断，特别是在创建双代理时。
