在上一篇我的Spring之旅（一）中，我们只是利用不带参数的请求返回一个网页或一段json，在实际的B/S、C/S网络交互中，请求中需要自定义的参数。本篇将简单地为之前的请求添加参数。
package com.nextgame.web;
import java.io.IOException;
import net.sf.json.*;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import javax.servlet.http.*;
@Controller
public class HelloController {
@RequestMapping("/view")
public String hello(@RequestParam(value="hello", required=false, defaultValue="World") String name, Model model) {
model.addAttribute("hello", name);
return "helloworld";
}
@RequestMapping("/json")
public void json(HttpServletRequest req,HttpServletResponse res,String method,String name) throws IOException
{
JSONObject obj = new JSONObject();
if(method.equals("sayhello"))
{
obj = this.sayhello(name);
}
else if(method.equals("sayhi"))
{
obj = this.sayhi(name);
}
obj.put("copyright", "wang hao");
res.getWriter().print(obj);
}
/*
* API:sayhello
*/
private JSONObject sayhello(String name)
{
JSONObject obj = new JSONObject();
obj.put("msg", "hello," + name +"!");
return obj;
}
/*
* API:sayhi
*/
private JSONObject sayhi(String name)
{
JSONObject obj = new JSONObject();
obj.put("msg", "hi," + name +"!");
return obj;
}
}
public void json(HttpServletRequest req,HttpServletResponse res,String method,JSONObject name) throws IOException
{
JSONObject obj = new JSONObject();
if(method.equals("sayhello"))
{
obj = this.sayhello(name.getString("name"));
}
else if(method.equals("sayhi"))
{
obj = this.sayhi(name.getString("name"));
}
obj.put("copyright", "wang hao");
res.getWriter().print(obj);
}
