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~
