微信授权登录用java获取code后再获取token出现40163，code bean used

Question

但是又没出错，我点击链接
https://open.weixin.qq.com/co...://39.108.80.19:8080/wxtest/callBackServlet&response_type=code&scope=snsapi_base&state=STATE#wechat_redirect
进入然后显示这样

然后再点击继续访问就去到回调页面中显示那段话40163。。。的
我的代码如下：

package servlet;

import Utils.AuthUtil;
import org.json.JSONObject;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.io.IOException;
import java.io.PrintWriter;

/**

public class CallBackServlet extends HttpServlet {


/**
 * 
 */
private static final long serialVersionUID = 1L;

//private static int i = 0;



@Override
protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
    
    
    
    String code =req.getParameter("code");
    
     

        String url="https://api.weixin.qq.com/sns/oauth2/access_token?appid=" + AuthUtil.APPID+
                "&secret=" +AuthUtil.APPSECRET+
                "&code=" +code+
                "&grant_type=authorization_code";
        
          JSONObject jsonObject= AuthUtil.doGetJson(url);
         PrintWriter writer = resp.getWriter();
        writer.print(jsonObject.toString()+"--666--"+code);

}
}

    JSONObject jsonObject=null;
    DefaultHttpClient defaultHttpClient=new DefaultHttpClient();
    HttpGet httpGet=new HttpGet(url);
    HttpResponse httpResponse = defaultHttpClient.execute(httpGet);
    HttpEntity httpEntity=httpResponse.getEntity();
    if(httpEntity!=null){
        String result= EntityUtils.toString(httpEntity,"UTF-8");
        jsonObject=new JSONObject(result);
        //System.out.println("jsonObject:  "+jsonObject);
    }
    httpGet.releaseConnection();
    return jsonObject;
}
}

试了很多种方法都是提示这样

你这个问题有解决嘛？楼主有用微信开放平台开发过微信订阅号吗？获取订阅号的openid？还请楼主赐教。
