2022-02-20 解决了Caused by: java.lang.IllegalArgumentException: Timestamp format must be yyyy-mm-dd h

问题出现情况：

   1、由于实体中生成了有参构造，无参构造则不自动生成，需手动生成（基础啊）。

为什么需要：

   Mybatis框架会调用这个默认构造方法来构造实例对象，即实体类需要通过Mybatis进行动态反射生成。反射的Class.forName("className").newInstance();需要对应的类提供一个无参构造  函数。

太难受了！！！！

搞了几天才发现 原来是实体类的 无参构造没有声明！！！！！！！！！！！！！
