SpringBoot应用实现向钉钉发送带图片的消息的两种方法总结

<!-- 方案A: snowheart的starter -->
<dependency>
    <groupId>cn.snowheart</groupId>
    <artifactId>spring-boot-dingtalk-robot-starter</artifactId>
    <version>1.0.3.RELEASE</version>
</dependency>

<!-- 方案B: javafamily的starter -->
<dependency>
    <groupId>club.javafamily</groupId>
    <artifactId>dingtalk-notification-spring-boot-starter</artifactId>
    <version>2.3.2-beta.13</version>
</dependency>

# 如果使用snowheart的starter
dingtalk:
  robot:
    prefix: https://oapi.dingtalk.com/robot/send
    access-token: your_access_token_here
    secret:
      secret-enabled: true
      secret-token: your_secret_here

# 如果使用javafamily的starter  
javafamily:
  notify:
    dingtalk:
      hook-url: https://oapi.dingtalk.com/robot/send?access_token=your_token
      enabled: true
