Transaction rolled back because it has been marked as rollback-only

最近在看程序日志的时候，发现频繁出现 Transaction rolled back because it has been marked as rollback-only这个异常，查了很久资料才知道是什么原因导致抛出这异常的，下面解析一下；

原因

字面上的意思就是：事务已回滚，因为它已被标记为仅回滚，那为什么会标记为仅回滚呢？

其实原因就是嵌套事务导致的，因为spring事务有传递性，spring默认的事务传播级别是PROPAGATION_REQUIRED，即当前上下文存在事务则用此事务，如果不存在事务则新建一个事务执行；

那么现在有A和B两个方法，这两个方法都开启了事务，A方法中调用B方法（因为都使用事务，默认的事务传播级别是PROPAGATION_REQUIRED，所以这过程中会使用同一个事务）；

当执行B方法的时候，B方法抛出异常，这个时候事务就会被标记为仅回滚（因为在B方法中抛出异常，B方法这事务本该是要回滚，所以会将B方法的事务标记为rollback-only）；

但是在A方法又catch到B方法抛的异常，但是A方法catch到异常后没有继续往上抛出，而是继续执行后面的代码，最后正常提交事务，那么就会抛出 Transaction rolled back because it has been marked as rollback-only这异常！（因为AB是用同一个事务，在B方法执行的时候这个事务就标记为rollback-only，然后A方法继续使用该事务，然后又执行事务提交的操作，所以最后会抛异常）

事例

 public void a() {
        try {
            SysInterfaceLogSettintModel model = new SysInterfaceLogSettintModel();
            model.setInterfaceCode("code");
            model.setInterfaceName("name");
            //这里做了保存操作
            this.save(model);
            //这里调用了b方法，是另外一个service的
            roleMenuService.b();
            //执行完提交事务
        }catch (Exception e ){
        	//a方法catch了异常但是没有继续抛出，事务会提交
            e.printStackTrace();
        }
    }
   
	public void b() throws Exception {
		//b方法抛出异常
		throw new Exception("Exception");
	}

最后会抛出异常
