添加事务@Transactional导致整个controller映射路径404

记一次代码不规范导致的问题，那时图省事，直接加@Transactional加在控制层，使用dao进行数据保存，没使用service。

• 问题原因：@Transactional加在控制层

        waterMessageDetailMapper.insertSelective(waterMessageDetail);
    }

    @GetMapping("/test")
    public String test(){
        return "test";
    }
}

解决方案

• waterMessageDetailMapper.insertSelective(waterMessageDetail);修改为 waterMessageDetailService.insertSelective(waterMessageDetail);
• 将@Transactional加入到serviceImpl

	@Transactional
    public int insertSelective(WaterMessageDetail record) {
        return waterMessageDetailMapper.insertSelective(record);
    }
