我想使用注释方法在spring mvc中创建一个示例项目，用户可以通过单击按钮导航到一个页面到另一个页面。我是spring mvc的新手，我创建了一个用于单页显示的示例项目

我期待着你的帮助。提前致谢

登录.java

 package credentials;

 public class Login {

private String name;
private String password;

public void setName(String name){
    this.name=name;
}
public String getName(){
    return name;
}

public void setPassword(String password){
    this.password=password;
}
public String getPassword(){
    return password;
}
  }

登录控制器.java

     package credentials;

    import org.apache.tomcat.jdbc.pool.Validator;
      import org.springframework.stereotype.Controller;
       import org.springframework.ui.ModelMap;
     import org.springframework.validation.BindingResult;
      import org.springframework.web.bind.annotation.ModelAttribute;
    import org.springframework.web.bind.annotation.RequestMapping;
     import org.springframework.web.bind.annotation.RequestMethod;
    import org.springframework.web.servlet.ModelAndView;


     @Controller
    public class LoginController {

@RequestMapping(value="/login")
public ModelAndView login(){
    return new ModelAndView("login","command",new Login());

}



@RequestMapping(value="/calc")
public ModelAndView Add(){
    return new ModelAndView("calc","command",new Login());

}


    }

登录.jsp

单击计算页面上的此“鼠标”按钮时，会发生以下错误

      HTTP Status 404 - 

    type Status report

    message 

   description The requested resource is not available.

添加后

    <form:input path="mouse"/>

在登录页面单击登录按钮时出现以下错误

         HTTP Status 500 - An exception occurred processing JSP page /WEB-INF/jsp/calc.jsp  at line 16

     type Exception report

       message An exception occurred processing JSP page /WEB-INF/jsp/calc.jsp at line 16

        description The server encountered an internal error that prevented it from fulfilling this request.

例外

            org.apache.jasper.JasperException: An exception occurred processing JSP page /WEB-INF/jsp/calc.jsp at line 16

        13: 
        14: <tr>

Spring 在 github 上提供了大量示例项目。

在这里查看他们的存储库

所以你想要的只是点击一个按钮，这会触发一个返回视图的弹簧端点。
