springmvc新手练习

package com.springmvc;
public class User {
Integer id;
String password;
public Integer getId() {
return id;
}
public void setId(Integer id) {
this.id = id;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}

}

//创建一个Users对象

package com.springmvc;

import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class UserController {
@RequestMapping("/login.action")
public String login(Integer id,String password,Model model)
{
User user=new User();
user.setId(id);
user.setPassword(password);
model.addAttribute("user",user);
return "success";

}

//访问到login页面
@RequestMapping("index.action")
public ModelAndView index()
{
ModelAndView mView=new ModelAndView("login");
return mView;
}

}

//创建一个Controller控制器
