前言

微信小程序消息订阅，向微信用户发送消息模块java实现方案。
发送订阅消息步骤：
1.初始化系统用户绑定微信唯一标识openId
2.前端唤起长期订阅通知提示
3.后端用系统用户绑定的微信openId发送消息

提示：以下是本篇文章正文内容，下面案例可供参考

一、需要准备哪些东西

1：微信小程序的APP_ID，APP_SECRET

java 订阅过滤 java 消息订阅_java

2：订阅消息模板id申请

java 订阅过滤 java 消息订阅_web app_02

二、使用步骤

系统用户绑定微信

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;
