问题和结果

要用户先发送一条消息给公众号，你才能发送成功

java 一键分享到微信 java发微信_经验分享_03


获取关注的用户openId

/**
     * 获得关注公众号所有openid
     * @return
     * @throws WxErrorException
     */
    @Override
    public List<String> getUserList() throws WxErrorException {
        WxMpUserList wxMpUserList = wxMpService.getUserService().userList(null);
        List<String> openids = wxMpUserList.getOpenids();
        return openids;
    }

既然有了openId集合和要发送的消息怎么群发

微信并没有提供群发接口–就在自己代码中迭代openId集合去循环发送
