Don't talk nonsense, just go to the code
1. Controller layer call code
/**
* 群发消息
* @param user
* @return
*/
@RequestMapping(value="/groupMessage",method=RequestMethod.POST,produces ="application/json;charset=utf-8")
public JSONObject Message(@RequestBody(required=false)JSONObject obje) {
JSONObject result=new JSONObject();
logger.info("-----------开始群发------------");
String content=obje.getString("content");//群发内容
Integer code=wechatMsg.GroupMessage(wechatMsg.getToken(),content);//群发消息
if(code==0) {
result.put("code",0);
result.put("data","群发成功");
}else {
result.put("code",1201);
result.put("data","微信群发消息失败");
}
return result;
}
2. Tool class WechatMsg code, the following is an example of mass text messaging. If mass text messaging is realized (for other messages, such as pictures and videos, please refer to the WeChat official account development document), you can copy it directly, and only need to modify the XXX The code is fine

3. If your requirement is group sending, then it is over here. If the requirement is group sending (that is, when is_to_all is set to false), you need to get the tag id first. You can call the following method to get the tag id and get the tag id. Fill in the tag_id variable in the code above. Note: The value of name in the code below cannot be the same as the existing label name in the official account. Only after the following code is successfully called can a new label be generated on the official account
/**
* 调用这个方法获取标签ID后,还要在公众号上给标签添加用户
* @param token
* @return
*/
public Integer getTab(String token) {
String sendMsgApi = "https://api.weixin.qq.com/cgi-bin/tags/create?access_token="+token;
//整体参数map
Map<String, Object> paramMap = new HashMap<String, Object>();
//相关map
Map<String, Object> dataMap1 = new HashMap<String, Object>();
dataMap1.put("name","test6");//这里写你要创建的标签名
paramMap.put("tag",dataMap1);
String back=doGetPost(sendMsgApi,"POST",paramMap);
System.out.println("请求获取标签接口返回:"+back);
JSONObject jsonObject =JSONObject.parseObject(back).getJSONObject("tag");//String转JSONObject，
Integer id=-1;//设id初始值为-1,如果最后返回id还是-1,代表获取标签失败
if(jsonObject!=null) {
id=jsonObject.getInteger("id");
}
return id;
}
