**一 资源文件**

1 英文资源文件

loginname= Login name:
    password = Password:
    submit = Submit
    welcome = Welcom {0} access fkit
    title = Login Page
    username = administrator

2 中文资源文件

loginname= \u767B\u5F55\u540D:
    password = \u5BC6\u7801:
    submit = \u63D0\u4EA4
    welcome = \u6B22\u8FCE {0} \u8BBF\u95EE\u75AF\u72C2\u8F6F\u4EF6
    title = \u767B\u5F55\u9875\u9762
    username = \u7BA1\u7406\u5458

**二 控制器**

package org.fkit.controller;
    
    import javax.servlet.http.HttpServletRequest;
    import org.fkit.domain.User;
    import org.springframework.stereotype.Controller;
    import org.springframework.ui.Model;
    import org.springframework.web.bind.annotation.ModelAttribute;
    import org.springframework.web.bind.annotation.PostMapping;
    import org.springframework.web.bind.annotation.RequestMapping;
    import org.springframework.web.servlet.support.RequestContext;
    
    @Controller
    public class UserController{
         
        @RequestMapping(value="/loginForm")
         public String loginForm(Model model){
            User user = new User();
            model.addAttribute("user",user);
            // 跳转页面
            return "loginForm";
        }
         
         @PostMapping(value="/login")
         public String login(
                 @ModelAttribute User user,
                 Model model,
                 HttpServletRequest request) {
             System.out.println(user);
             // 如果登录名是fkit，密码是123456，则验证通过
             if(user.getLoginname()!=null && user.getLoginname().equals("fkit")
                 && user.getPassword()!=null && user.getPassword().equals("123456")){
                 //从后台代码获取国际化信息username
                 RequestContext requestContext = new RequestContext(request);
                 String username = requestContext.getMessage("username");
                 // 将获取的username信息设置到User对象并设置到Model当中
                 user.setUsername(username);
                 model.addAttribute("user", user);
                 return "success";
             }
             return "error";
            
         }
    }

**三 领域模型**

package org.fkit.domain;
    import java.io.Serializable;
    
    // 域对象，实现序列化接口
    public class User implements Serializable{
         
         private static final long serialVersionUID = 1L;
         
         private String loginname;
         private String password;
         private String username;
         public User() {
               super();
               // TODO Auto-generated constructor stub
         }
         public String getLoginname() {
               return loginname;
         }
         public void setLoginname(String loginname) {
               this.loginname = loginname;
         }
         public String getPassword() {
               return password;
         }
         public void setPassword(String password) {
               this.password = password;
         }
         public String getUsername() {
               return username;
         }
         public void setUsername(String username) {
               this.username = username;
         }
         @Override
         public String toString() {
               return "User [loginname=" + loginname + ", password="  + password
                         + ", username=" + username + "]";
         }
         
         
         
    }

**四 视图**
