Answer 1

1、Unknown entity: com.viststem.yjj.user.model.User--------未知实体类：可能实体类未注入
2、com.viststem.user.dao.impl.UserDaoImpl.addUser(UserDaoImpl.java:71)------用户DAO实现 类71行有错误 ，用鼠标左键点击UserDaoImpl.java就会跳到错误处。
3、com.visystem.user.controller.UserController1.addUser(UserController1.java:49)-----用户controller的49行有问题 点击过去查看
