1.小程序推送信息列如我们去餐厅等位有预约提醒，剩余桌数

首先申请一个小程序，微信开放平台：小程序

2.申请小程序信息，申请信息模板

appid

AppSecret

3.根据开发文档开发

subscribeMessage.send | 微信开放文档

4.代码如下：

引入依赖

org.apache.httpcomponents

httpclient

4.5.2

先准备一个HTTP工具类Z

import org.apache.http.HttpEntity;

import org.apache.http.client.methods.CloseableHttpResponse;

import org.apache.http.client.methods.HttpGet;

import org.apache.http.client.methods.HttpPost;

import org.apache.http.conn.ssl.TrustSelfSignedStrategy;

import org.apache.http.entity.StringEntity;

import org.apache.http.impl.client.CloseableHttpClient;

import org.apache.http.impl.client.HttpClients;

import org.apache.http.ssl.SSLContexts;

import org.apache.http.util.EntityUtils;

import java.io.IOException;
