一、服務(wù)器基本信息交互

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

 /** * 確認(rèn)請(qǐng)求來(lái)自微信服務(wù)器 */

public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { // 微信加密簽名  String signature = request.getParameter("signature"); // 時(shí)間戳  String timestamp = request.getParameter("timestamp"); // 隨機(jī)數(shù)  String nonce = request.getParameter("nonce"); // 隨機(jī)字符串  String echostr = request.getParameter("echostr");  

        PrintWriter out = response.getWriter(); // 通過(guò)檢驗(yàn)signature對(duì)請(qǐng)求進(jìn)行校驗(yàn)，若校驗(yàn)成功則原樣返回echostr，表示接入成功，否則接入失敗  if (SignUtil.checkSignature(signature, timestamp, nonce)) {  
            out.print(echostr);
        }  
        out.close();  
        out = null;  
    }

/** * 處理微信服務(wù)器發(fā)來(lái)的消息  */

public void doPost(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException { // 將請(qǐng)求、響應(yīng)的編碼均設(shè)置為UTF-8（防止中文亂碼）  request.setCharacterEncoding("UTF-8");  
            response.setCharacterEncoding("UTF-8"); // 調(diào)用核心業(yè)務(wù)類接收消息、處理消息  String respMessage = CoreService.processRequest(request); // 響應(yīng)消息  PrintWriter out = response.getWriter();
