在数据库中获取当前服务号的所有粉丝数据
新建粉丝类，定时任务全局定时刷新 access_token (这是接口调用凭证推荐定时任务刷新入库，官网链接：https://developers.weixin.qq.com/doc/offiaccount/Basic_Information/Get_access_token.html)
类里面定义 boolean，正在更新不允许再次进入
static boolean isPullWxFsing = false;//正在更新粉丝列表
if (isPullWxFsing) {
//在更新粉丝列表，请结束后再点击更新
message = "正在更新粉丝列表，请结束后再点击更新";
return;
}
isPullWxFsing = true;
Map<String, String> map = new HashMap<>();
String next_openid = "";// 服务号粉丝量大接口会返回一个next_openid 下次调接口要用这个 每次接口返回1万openid
for (int i = 0; i < Integer.MAX_VALUE; i++) {
System.out.println("进来了" + (i + 1) + "次");
map = updateFans(h, next_openid, i);
String isok = map.get("isok") + "";
next_openid = map.get("next_openid") + "";
if (isok.equals("1")) {
isPullWxFsing = false;
message = "接口未知错误，请稍后重试";
out.print("<script>mt.show('" + message + "',1,'" + nexturl + "');</script>");
return;
}
if (next_openid.length() == 0) {
isPullWxFsing = false;
break;
