处理action的java类

package push;



import java.io.IOException;



import javax.servlet.http.HttpServletRequest;

import javax.servlet.http.HttpServletResponse;



import org.springframework.stereotype.Controller;

import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestMethod;

import org.springframework.web.bind.annotation.RequestParam;



/**

@Controller

@RequestMapping("/api")

public class ApiController {



    @RequestMapping(value = "/age.s", method = RequestMethod.GET)

    public void methodAge(HttpServletRequest request, HttpServletResponse response,

            @RequestParam(value="id", required=true) String id) {

        System.out.println(id);

        String json = "{name:'中文',age:23, requestid:"+ id +"}";

        try {

            //response.setContentType("text/html;charset=UTF-8");

            response.getWriter().print(json);

        } catch (IOException e) {

            e.printStackTrace();

        }

    }

}

 打好war包，找个tomcat容器部署下（webapps下），通过  http://localhost:8080/api/age.s?id=1  即可访问

enjoy it~
