java创建http接口

1.修改web.xml文件

   
        TestHTTPServer
        com.atoz.http.SmsHTTPServer
   
   
        TestHTTPServer
        /httpServer
   

2.新建SmsHTTPServer.java文件

package com.atoz.http;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import com.atoz.action.order.SendSMSAction;
import com.atoz.util.SpringContextUtil;

public class SmsHTTPServer  extends HttpServlet {
   
    private static final long serialVersionUID = 1L;

    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
  response.setContentType("text/html;charset=utf-8");
     request.setCharacterEncoding("utf-8");
     response.setCharacterEncoding("utf-8");
     PrintWriter out = response.getWriter();
      String content = request.getParameter("content");
       //String content = new String(request.getParameter("content").getBytes("iso-8859-1"), "utf-8"); 
        String mobiles = request.getParameter("mobiles");
        String businesscode = request.getParameter("businesscode");
        String businesstype = request.getParameter("businesstype");
        if (content == null || "".equals(content) || content.length() <= 0) {
         System.out.println("http call failed,参数content不能为空,程序退出");
        } else if (mobiles == null || "".equals(mobiles)
                || mobiles.length() <= 0) {
         System.out.println("http call failed,参数mobiles不能为空,程序退出");
        } else {
         /*SendSMSServiceImpl send = new SendSMSServiceImpl();*/
         SendSMSAction sendSms = (SendSMSAction) SpringContextUtil.getBean("sendSMS");
         sendSms.sendSms(content, mobiles, businesscode, businesstype);
         System.out.println("---http call success---");
        }
        out.close();
    }

    public void doPost(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {
        this.doGet(request, response);
    }
}

3.调用http接口

String content = "测试";
  content = URLEncoder.encode(content, "utf-8");
  String url = "http://localhost:8180/atoz_2014/httpServer?content=" + content + "&mobiles=15301895007";
  
  URL httpTest;
  try {
   httpTest = new URL(url);
   BufferedReader in;
   try {
    in = new BufferedReader(new InputStreamReader(
      httpTest.openStream()));
    String inputLine = null;
    String resultMsg = null;
    //得到返回信息的xml字符串
    while ((inputLine = in.readLine()) != null)
     if(resultMsg != null){
      resultMsg += inputLine;
     }else {
      resultMsg = inputLine;
     }
    in.close();
   } catch (MalformedURLException e) {
    e.printStackTrace();
   }
  } catch (IOException e) {
   // TODO Auto-generated catch block
   e.printStackTrace();
  }
