服务器配置如下

package com.dongpeng;

import java.security.MessageDigest;
import java.util.Arrays;

import javax.servlet.http.HttpServletResponse;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;

@Controller
@SpringBootApplication
public class Application {
    public static final String TOKEN = "lianghao_token";

    @RequestMapping("/")
    @ResponseBody
    public void index(String signature, String timestamp, String nonce, String echostr,HttpServletResponse response)throws Exception {
        System.out.println("signature:" + signature);
        System.out.println("timestamp:" + timestamp);
        System.out.println("nonce:" + nonce);
        System.out.println("echostr:" + echostr);
        System.out.println("TOKEN:" + TOKEN);
        String[] params = new String[] { TOKEN, timestamp, nonce };
        Arrays.sort(params);
        // 将三个参数字符串拼接成一个字符串进行sha1加密
        String clearText = params[0] + params[1] + params[2];
        String algorithm = "SHA-1";
        String sign = new String(org.apache.commons.codec.binary.Hex
                .encodeHex(MessageDigest.getInstance(algorithm).digest((clearText).getBytes()), true));
        // 开发者获得加密后的字符串可与signature对比，标识该请求来源于微信
        if (signature.equals(sign)) {
            response.getWriter().print(echostr);
        }
    }

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}
