exception

org.springframework.web.util.NestedServletException: Request processing failed; nested exception is org.mybatis.spring.MyBatisSystemException: nested exception is org.apache.ibatis.reflection.ReflectionException: Error instantiating class com.heitian.ssm.model.User with invalid types () or values (). Cause: java.lang.NoSuchMethodException: com.heitian.ssm.model.User.<init>()org.springframework.web.servlet.FrameworkServlet.processRequest(FrameworkServlet.java:980)org.springframework.web.servlet.FrameworkServlet.doGet(FrameworkServlet.java:859)javax.servlet.http.HttpServlet.service(HttpServlet.java:624)org.springframework.web.servlet.FrameworkServlet.service(FrameworkServlet.java:844)javax.servlet.http.HttpServlet.service(HttpServlet.java:731)org.apache.tomcat.websocket.server.WsFilter.doFilter(WsFilter.java:52)org.springframework.web.filter.CharacterEncodingFilter.doFilterInternal(CharacterEncodingFilter.java:121)org.springframework.web.filter.OncePerRequestFilter.doFilter(OncePerRequestFilter.java:107)


异常原因:

public User(Long id, String userName, String userPhone, String userEmail, String userPwd, String pwdSalt, Date createTime, Date modifyTime, Short isDelete) {    this.id = id;    this.userName = userName;    this.userPhone = userPhone;    this.userEmail = userEmail;    this.userPwd = userPwd;    this.pwdSalt = pwdSalt;    this.createTime = createTime;    this.modifyTime = modifyTime;    this.isDelete = isDelete;}
添加了构造函数,需要注意的是:有时候少了构造函数也会报错,


解决方法:去掉pojo中的构造函数
