用手动回滚，代替抛异常回滚

	@Override
	@Transactional(readOnly = false, propagation = Propagation.REQUIRED, rollbackFor=Exception.class, timeout=10)
	public Map<String, Object> jerryRb() throws JerryException{
		Map<String, Object> resultMap = new HashMap<>();
		
		//操作1，创建一首诗
		Poem poem = new Poem();
		poem.setAuthor("笨笨");
		poem.setContent("666啊");
		poem.setTitle("poem");
		poemMapper.insertSelective(poem);
		
		//操作2，结果必须真，否则回滚
		boolean op2result = false;
		
		// 判断操作2的结果
		if(op2result){
			//手动回滚
			TransactionAspectSupport.currentTransactionStatus().setRollbackOnly();
			//返回错误信息
			resultMap.put("msg","error");
			return resultMap;
		}
		
		resultMap.put("msg","success");
		return resultMap;
		
	}
