JAVA 推送釘釘消息

 

1，添加釘釘機器人；釘釘群 = > 群設置 => 智能群助手 => 添加機器人 => 自定義機器人

 

 

 

 

 

2，添加SDK配置，下載jar

        <!-- 釘釘消息推送 -->
        <dependency>
            <groupId>com.aliyun</groupId>
            <artifactId>alibaba-dingtalk-service-sdk</artifactId>
            <version>1.0.1</version>
            <exclusions>
                <exclusion>
                    <groupId>log4j</groupId>
                    <artifactId>log4j</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

至於怎么添加到本地maven和上傳到私服庫，在其他博客中有詳細講解。

 

3，代碼實現
