Java接入飞书发送通知消息

添加依赖

        <!--飞书推送-->
        <dependency>
            <groupId>com.larksuite.oapi</groupId>
            <artifactId>oapi-sdk</artifactId>
            <version>2.4.22</version>
        </dependency>

创建应用，添加机器人

开通权限

制作卡片

这里配置了一个变量，用来接收具体的消息内容

Java代码

					//飞书推送消息
					List<String> targetUserIds = new ArrayList<>();//接收消息的open_id
					targetUserIds.add(iDictValue.getDictValue("jcNotice",underTakeId));
					String content = balanceUser+" 平衡的集中采购合同号("+poNo+")，已经生成，请及时处理！";
					feishuUserService.batchPushMessage(targetUserIds, content);
