SpringBoot报错：nested exception is org.apache.ibatis.executor.ExecutorException: No constructor found in com.tuyrk.test.User matching [java.lang.Long, java.lang.String, java.lang.String]
错误提示：
Caused by: org.apache.ibatis.executor.ExecutorException: No constructor found in com.tuyrk._161_java_socket.project6.entity.User matching [java.lang.Long, java.lang.String, java.lang.String]
这里就有点坑了，明明提示的是没有三个参数的构造函数，然而我添加上三个参数的构造函数还是报错
解决方法：
添加一个无参构造函数（可以不添加三个参数的构造函数）。
在这里可以理解成使用Mybatis查询一个实例时，这个抽象实体类必须有一个无参构造方法
注：
默认情况下，每一个实体类都有一个无参构造函数。
如果我们自己添加一个有参构造函数，则默认的无参构造函数失效，需手动添加无参构造函数
