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

1 package weixin.guanjia.core.controller; 2  3 import java.io.IOException; 4 import java.io.PrintWriter; 5 import java.util.List; 6  7 import javax.servlet.http.HttpServletRequest; 8 import javax.servlet.http.HttpServletResponse; 9 10 import org.springframework.beans.factory.annotation.Autowired;11 import org.springframework.stereotype.Controller;12 import org.springframework.web.bind.annotation.RequestMapping;13 import org.springframework.web.bind.annotation.RequestMethod;14 import org.springframework.web.bind.annotation.RequestParam;15 16 import weixin.guanjia.account.entity.WeixinAccountEntity;17 import weixin.guanjia.account.service.WeixinAccountServiceI;18 import weixin.guanjia.core.service.impl.WechatService;19 import weixin.guanjia.core.util.SignUtil;20 21 @Controller22 @RequestMapping("/wechatController")23 public class WechatController {24     @Autowired25     private WechatService wechatService;26     @Autowired27     private WeixinAccountServiceI weixinAccountService;28 29     /**30      * 与微信对接的接口31      * @注释添加 geenkDC32      * @time 2015-07-09 14:34:0733      * @param request34      * @param response35      * @param signature36      * @param timestamp37      * @param nonce38      * @param echostr39      */40     @RequestMapping(params="wechat", method = RequestMethod.GET)41     public void wechatGet(HttpServletRequest request,42             HttpServletResponse response,43             @RequestParam(value = "signature") String signature,44             @RequestParam(value = "timestamp") String timestamp,45             @RequestParam(value = "nonce") String nonce,46             @RequestParam(value = "echostr") String echostr) {47 48         List
      
        weixinAccountEntities = weixinAccountService.getList(WeixinAccountEntity.class);49         for (WeixinAccountEntity account : weixinAccountEntities) {50             if (SignUtil.checkSignature(account.getAccounttoken(), signature,51                     timestamp, nonce)) {52                 try {53                     response.getWriter().print(echostr);54                     break;55                 } catch (IOException e) {56                     // TODO Auto-generated catch block57                     e.printStackTrace();58                 }59             }60         }61     }62 63     /**64      * 统一接收微信服务器推送的接口65      * @注释添加 geenkDC66      * @time 2015-07-09 14:34:5667      * @param response68      * @param request69      * @throws IOException70      */71     @RequestMapping(params = "wechat", method = RequestMethod.POST)72     public void wechatPost(HttpServletResponse response,73             HttpServletRequest request) throws IOException {74         String respMessage = wechatService.coreService(request);75         PrintWriter out = response.getWriter();76         out.print(respMessage);77         out.close();78     }79 80 }
      

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，
