JAVA 推送钉钉消息

 

1，添加钉钉机器人；钉钉群 = > 群设置 => 智能群助手 => 添加机器人 => 自定义机器人

 

 

 

 

 

2，添加SDK配置，下载jar

        <!-- 钉钉消息推送 -->
        <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>

至于怎么添加到本地maven和上传到私服库，在其他博客中有详细讲解。

 

3，代码实现

            OapiRobotSendRequest.Text text = new OapiRobotSendRequest.Text();
            text.setContent(in.getText());
            request.setText(text);
        }

        OapiRobotSendResponse response = client.execute(request);
        log.info("钉钉推送返回结果：" + response);

    }

    public static void main(String[] args) throws Exception {

        List<String> mobileList = new ArrayList<>();
        mobileList.add("156xxxxxxxx");

        SendMessageIn in = new SendMessageIn();
        in.setMsgType(TEXT);

        in.setMobileList(mobileList);
        in.setWebhook("https://oapi.dingtalk.com/robot/send?access_token=xxxxx");
        in.setSecret("签");
        in.setText("桃花坞里桃花庵，桃花庵下桃花仙");

        sendMessage(in);

    }

}



import lombok.Data;
