1. HOME 控制器

   package ghy.webapp.myapp;import java.text.DateFormat;import java.util.Date;import java.util.Locale;import org.slf4j.Logger;import org.slf4j.LoggerFactory;import org.springframework.stereotype.Controller;import org.springframework.ui.Model;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.RequestParam;/** * Handles requests for the application home page. */@Controllerpublic class HomeController {
   private static final Logger logger = LoggerFactory.getLogger(HomeController.class);
   /**
    * Simply selects the home view to render by returning its name.
    */
   @RequestMapping(value = "/", method = RequestMethod.GET)
   public String home(Locale locale, Model model) {
   logger.info("Welcome home! The client locale is {}.", locale);
   Date date = new Date();
   DateFormat dateFormat = DateFormat.getDateTimeInstance(DateFormat.LONG, DateFormat.LONG, locale);
   String formattedDate = dateFormat.format(date);
   model.addAttribute("serverTime", formattedDate );
   return "home";
   }
   @RequestMapping(value = "/Two", method = RequestMethod.GET)
   public String Two(
   int id,Model model
   ) {
   logger.info("two");
   System.out.println("hello2 action:"+id);          model.addAttribute("name", "huangjie");          //这个只有值没有键的情况下,使用Object的类型作为key,String-->string          model.addAttribute("ok");  
   return "Two";
   }
   }

2. Two.jsp 视图

   <%@ page language="java" contentType="text/html; charset=utf-8"    pageEncoding="utf-8"%>    <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">  <title>欢迎</title>      <h2>Hello World!</h2>      <span>当前IP：<%=request.getRemoteAddr() %></span>    

3. Two控制器

   package ghy.webapp.myapp;import org.springframework.stereotype.Controller;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestParam;import org.springframework.web.bind.annotation.ResponseBody;@Controller  public class TwoController {            @RequestMapping("login") //用来处理前台的login请求      private @ResponseBody String hello(              @RequestParam(value = "username", required = false)String username,              @RequestParam(value = "password", required = false)String password              ){          return "Hello "+username+",Your password is: "+password;                }   }

   环境：sts +tomcat
4. 运行 http://localhost:8080/myapp 执行home控制器 ，http://localhost:8080/myapp/Two?id=3525是调用 Two控制器传参id
