下面有張圖片，介紹配置：

下面來看看Token驗證。注意：本次微信開發專欄，全部使用spring boot進行開發。
CODE：servlet

import java.io.IOException;
import java.io.PrintWriter;

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

import com.shw.vote.web.service.AuthService;

public class ServerPortal extends HttpServlet {
    private static final long serialVersionUID = 1L;
    //我們的Token
    private static final String token = "tokensh";

    /**
     * @see HttpServlet#HttpServlet()
     */
 

    public ServerPortal() {
        super();
    }

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        String signature = request.getParameter("signature"
 
);
        String timestamp = request.getParameter("timestamp");
        String nonce = request.getParameter("nonce");
        String echostr = request.getParameter("echostr");
        System.out.println("signature:" + signature);
        System.out.println("timestamp:" + timestamp);
        System.out.println("nonce:" + nonce);
        System.out.println("echostr:" + echostr);
        PrintWriter pw = response.getWriter();
        pw.append(echostr);
        pw.flush();
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }

}

spring boot需要注入servlet：

@Bean  
public ServletRegistrationBean testServletRegistration() {  
    ServletRegistrationBean registration = new ServletRegistrationBean(new ServerPortal());  
    //我們的URL
    registration.addUrlMappings("/portal");  
    return registration;  
}

上面我們設定Token為tokensh:
private static final String token = “tokensh”;

Token , URL都設定了，提交，提示提交成功，則配置完畢。
