springMVC调微信接口实现关注时消息回复和自动回复功能

微信一直是一个比较热门的词汇，今天我主要简单的搭建一下springMVC版本的微信接口调用

废话不多说，贴代码

RequestWeiXinWXY.java

package com.beijing.wei.weixin.weixingyu;import java.io.IOException;import java.io.PrintWriter;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 com.beijing.wei.base.BaseContractor;import com.beijing.wei.util.common.CommonUtil1;import com.beijing.wei.util.file.SysLogs;import com.beijing.wei.weixin.service.WXYweixinService;@Controller@RequestMapping(value = "/wxyweixin")public class RequestWeiXinWXY extends BaseContractor {@Autowiredprivate WXYweixinService wxyweixinService;/** * 校验信息是否是从微信服务器发过来的。 *  * @param weChat * @param out */@RequestMapping(method = { RequestMethod.GET })public void valid(WeChat weChat, PrintWriter out) {String signature = weChat.getSignature(); // 微信加密签名String timestamp = weChat.getTimestamp(); // 时间戳String nonce = weChat.getNonce();// 随机数String echostr = weChat.getEchostr();// 随机字符串// 通过检验signature对请求进行校验，若校验成功则原样返回echostr，表示接入成功，否则接入失败if (ValidateUtil.validate(ValidateUtil.WXY_TOKEN, weChat)) {out.print(echostr);} else {System.out.println("不是微信服务器发来的请求,请小心!");}out.flush();out.close();}/** * 微信消息的处理 *  * @param request * @param out * @throws Throwable  */@RequestMapping(method = { RequestMethod.POST })public void dispose(HttpServletRequest request, HttpServletResponse response)throws Throwable {/* 消息的接收、处理、响应 */// 将请求、响应的编码均设置为UTF-8（防止中文乱码）request.setCharacterEncoding("UTF-8");response.setCharacterEncoding("UTF-8");// 调用核心业务类接收消息、处理消息String respMessage = ValidateUtil.automatismRestoreEntity(ValidateUtil.automatismRestoreDocument(ValidateUtil.getStringPostWeixin(request)));SysLogs.print("INFO", "***************************$$$*** "+respMessage);// 响应消息PrintWriter out = response.getWriter();out.print(respMessage);out.flush();out.close();}}

 

下面是处理request请求获取微信参数：

ValidateUtil.java

         Arrays.sort(tmpArr);          String tmpStr=ArrayToString(tmpArr);          tmpStr=SHA1Encode(tmpStr);          if(tmpStr.equalsIgnoreCase(weChat.getSignature())){              return true;          }else{              return false;          }  } //数组转字符串     public static String ArrayToString(String [] arr){         StringBuffer bf = new StringBuffer();         for(int i = 0; i < arr.length; i++){          bf.append(arr[i]);         }         return bf.toString();     }     //sha1加密     public static String SHA1Encode(String sourceString) {         String resultString = null;         try {            resultString = new String(sourceString);            MessageDigest md = MessageDigest.getInstance("SHA-1");            resultString = byte2hexString(md.digest(resultString.getBytes()));         } catch (Exception ex) {         }         return resultString;     }      public static String byte2hexString(byte[] bytes) {          StringBuffer buf = new StringBuffer(bytes.length * 2);

         }          return buf.toString().toUpperCase();      }      /**     * <p>传值</p>     * @param request 当前post值     * return String     */    public static String getStringPostWeixin(HttpServletRequest request){    StringBuilder buffer = new StringBuilder();

                 } catch (IOException e) {                      e.printStackTrace();                      SysLogs.print("INFO", "IO 异常");                SysLogs.print("WARN", e);                }              }          }          return buffer.toString();      }                       /**     * <p>传入数据转为document</p>     * @param domStr 数据字符串     * reuturn document     */    public static Document automatismRestoreDocument(String domStr){    Document document=null;

下面是实体：WeChat

 

package com.beijing.wei.weixin.weixingyu;public class WeChat {private String signature;private String timestamp;private String nonce;private String echostr;public String getSignature() {return signature;}public void setSignature(String signature) {this.signature = signature;}public String getTimestamp() {return timestamp;}public void setTimestamp(String timestamp) {this.timestamp = timestamp;}public String getNonce() {return nonce;}public void setNonce(String nonce) {this.nonce = nonce;}public String getEchostr() {return echostr;}public void setEchostr(String echostr) {this.echostr = echostr;}}
