 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;
}
  }

Logincontroller.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.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());

}


    }

添加后

    <form:input path="mouse"/>

Spring在github上提供的许多示例项目已经做到了这一点

看看他们的存储库

因此，您只需单击一个按钮，就会触发一个spring端点，返回一个视图。

我没有创建一个示例，但它显示了错误。您应该执行更多示例并遵循totorials，然后如果您有问题，发布它：）发布显示错误的代码
