事务不起作用 Closing non transactional SqlSession

标签：

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.

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(){
        
    }

}
