【Java开发】Java实现调用微信机器人，发送企业微信通知_java 企业微信推送机器人消息-CSDN博客
-------------------------------------------------------------------------------------------------------------------------------
企业微信机器人发送消息
- 一、可能需要的依赖
- 二、机器人地址号查看
- 三、效果展示
- 四、具体代码
一、可能需要的依赖
<dependency>
<groupId>org.apache.httpcomponents</groupId>
<artifactId>httpclient</artifactId>
<version>4.3.5</version>
</dependency>
<!-- https://mvnrepository.com/artifact/com.fasterxml.jackson.core/jackson-databind -->
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-databind</artifactId>
<version>2.9.3</version>
</dependency>

<version>1.1.23</version>
</dependency>
<dependency>
<groupId>commons-lang</groupId>
<artifactId>commons-lang</artifactId>
<version>2.6</version>
</dependency>
二、机器人地址号查看
新建一个群聊机器人，可以查看机器人的接口地址，不需要密钥和企业id号
三、效果展示
输如需要发送的消息
获取返回值
微信收到消息
四、具体代码
如果觉得不错就点个赞吧！！
