jeewx的使用_01 接入和验证

jeewx是java语言的用于开发微信公共平台的一个框架，有人说很臃肿，但个人感觉还不错，仁者见仁智者见智吧，

下面简单介绍工作原理:

1、下载

要使用jeewx需要先下载其源码

jeewx介绍：http://www.oschina.net/p/jeewx

下载地址：http://git.oschina.net/jeecg/jeewx

2、使用

首先要在安装好的jeewx中填写需要二次开发的微信公众号的基本信息

然后登录微信公众平台，在基本设置中填写url

URL(服务器地址)

http://域名/jeewx/wechatController.do?wechat

当开发者填写了服务器配置后，用户消息和开发者需要的事件推送，将会被转发到该URL中

 

3、打开WechatController.java

 package weixin.guanjia.core.controller;

 import java.io.IOException;
 import java.io.PrintWriter;
 import java.util.List;

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

 import org.springframework.beans.factory.annotation.Autowired;
 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;

 import weixin.guanjia.account.entity.WeixinAccountEntity;
 import weixin.guanjia.account.service.WeixinAccountServiceI;
 import weixin.guanjia.core.service.impl.WechatService;
 import weixin.guanjia.core.util.SignUtil;

 @Controller
 @RequestMapping("/wechatController")
 public class WechatController {
     @Autowired
     private WechatService wechatService;
     @Autowired
     private WeixinAccountServiceI weixinAccountService;

     /**
      * 与微信对接的接口
      * @注释添加 geenkDC
      * @time 2015-07-09 14:34:07
      * @param request
      * @param response
      * @param signature
      * @param timestamp
      * @param nonce
      * @param echostr
      */
     @RequestMapping(params="wechat", method = RequestMethod.GET)
     public void wechatGet(HttpServletRequest request,
             HttpServletResponse response,
             @RequestParam(value = "signature") String signature,
             @RequestParam(value = "timestamp") String timestamp,
             @RequestParam(value = "nonce") String nonce,
             @RequestParam(value = "echostr") String echostr) {

         List<WeixinAccountEntity> weixinAccountEntities = weixinAccountService.getList(WeixinAccountEntity.class);
         for (WeixinAccountEntity account : weixinAccountEntities) {
             if (SignUtil.checkSignature(account.getAccounttoken(), signature,
                     timestamp, nonce)) {
                 try {
                     response.getWriter().print(echostr);
                     break;
                 } catch (IOException e) {
                     // TODO Auto-generated catch block
                     e.printStackTrace();
                 }
             }
         }
     }

     /**
      * 统一接收微信服务器推送的接口
      * @注释添加 geenkDC
      * @time 2015-07-09 14:34:56
      * @param response
      * @param request
      * @throws IOException
      */
     @RequestMapping(params = "wechat", method = RequestMethod.POST)
     public void wechatPost(HttpServletResponse response,
             HttpServletRequest request) throws IOException {
         String respMessage = wechatService.coreService(request);
         PrintWriter out = response.getWriter();
         out.print(respMessage);
         out.close();
     }

 }

可以看到当微信的服务器把request推送到该controller之后，剩下的工作就有wechatService来完成了，由于我的wechatService已经经过修改，这里就不在贴出，相信有java基础的博友一看便知，
