万能方法解决——You have an error in your SQL syntax
问题分析
显而易见,肯定是你的SQL语句在执行的时候出现了语法错误
第一步
在xml文件中配置以下内容来启动MyBatis的debug模式:
logging:
level:
com.chat.mapper: debug #这里修改成你们自己mapper类的包路径
做好上面步骤之后,重启服务,再次进行测试,然后就可以在控制台看到执行的SQL语句了,下面是示例:
第二步
知道SQL语句之后,就可以进行分析啦,比如用用MySql执行一下等方式,大的来说有以下几种情况:
1、基本句法错误
2、表名或者字段名与SQL中的关键词同名
3、参数传入时未加 '(单引号)
4、..........
第三步
经过上面两步,想必大家都知道自己的问题出在哪里了,接下来就是对症下药即可
