更新時(shí)間：2022年04月17日 11:39:44 作者：李日興lrx

本文主要介紹了SpringBoot小程序推送信息的項(xiàng)目實(shí)踐，文中通過示例代碼介紹的非常詳細(xì)，對大家的學(xué)習(xí)或者工作具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面隨著小編來一起學(xué)習(xí)學(xué)習(xí)吧

1.小程序推送信息列如我們?nèi)ゲ蛷d等位有預(yù)約提醒，剩余桌數(shù)

首先申請一個(gè)小程序，微信開放平臺：小程序

2.申請小程序信息，申請信息模板

appid

AppSecret

3.根據(jù)開發(fā)文檔開發(fā)

subscribeMessage.send | 微信開放文檔

4.代碼如下：

引入依賴

 <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.2</version>
    </dependency>

先準(zhǔn)備一個(gè)HTTP工具類Z
