MyBatis报错：Cannot determine value type from string....

报错信息：

org. springframework. web. util. NestedServletExcepti on:Request processing f ailed; 
nested exception is org.springframework. dao. DataIntegrityViolationExceptionError attempting to Cannot determine. value tvpe from string ” 2019-9-25 05:11: 48’nested ex ception is :java. sql. SQLDat aException: Cannot determine value tvpe from string ’2019-9-25 05: 11: 48 

 

新建查询后出现了这个错误，经发现是实体类接收数据库数据类型不匹配导致的。（字段和属性没有对上）

日期格式在经过DATE_FORMAT之后

DATE_FORMAT(update_time,'%Y-%c-%d %h:%i:%s') as 'update_time',

使用Date类型属性接收报错，修改后使用String类型的属性接收。

 

还有一种情况也会导致报这种错：

还有一种情况，构造函数问题，有参构造创建后，无参构造没有创建，也会导致这个问题。弄了一下午，换数据库、换字段、换属性名都没解决，最后想起来是不是缺少无参构造了
