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，
