事务不起作用 Closing non transactional SqlSession

In proxy mode (which is the default), only external method calls coming in through the proxy are intercepted. This means that self-invocation, in effect, a method within the target object calling another method of the target object, will not lead to an actual transaction at runtime even if the invoked method is marked with @Transactional.

http://docs.spring.io/spring/docs/4.2.0.RC1/spring-framework-reference/htmlsingle/#transaction-declarative-annotations

说明：代理模式中，只拦截外部方法调用，开启事务。类内部调用无法实现事务控制。

错误示例：

public class Tx {

    public void a(){

        b();

    }

    @Transactional(propagation = Propagation.REQUIRED)

    public void b(){

    }

}

正确示例：

public class Tx {

    @Transactional(propagation = Propagation.REQUIRED)

    public void a(){

        b();

    }

    public void b(){

    }

}
