企业号主动发送群聊通知：
步骤：

1. 通过后台的AppKey和AppSecret获取到请求的access_token:
   文档地址：https://ding-doc.dingtalk.com/document#/org-dev-guide/obtain-access_token

/**
 2. 获取token请求接口
 3.  4. @param appKey    密钥
 5. @param appSecret 密钥
 6. @return token
 */
public String getToken(String appKey, String appSecret) {
    //获取token值
    String token = "";
    try {
        DefaultDingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/gettoken");
        OapiGettokenRequest request = new OapiGettokenRequest();
        request.setAppkey(appKey);
        request.setAppsecret(appSecret);
        request.setHttpMethod("GET");
        OapiGettokenResponse response = client.execute(request);
        token = response.getAccessToken();
        return token;
    } catch (Exception e) {
        log.info("钉钉异常" + e);
    }
    return token;
}

2. 创建群聊前需要知道用户的userId，可通过用户手机号获取：
   文档地址：https://ding-doc.dingtalk.com/document#/org-dev-guide/get-userid-By-Mobile

/**
 1. 获取用户的userId
 2. @param phone 手机号
 3. @param token token值
 4. @return userId
 */
public String getUserId(String phone,String token) {
    String userId = "";
    try {
        DingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/topapi/v2/user/getbymobile");
        OapiV2UserGetbymobileRequest req = new OapiV2UserGetbymobileRequest();
        req.setMobile(phone);
        OapiV2UserGetbymobileResponse rsp = client.execute(req, token);
        userId = rsp.getResult().getUserid();
    } catch (Exception e) {
        log.info("钉钉异常" + e);
    }
    return userId;
}

3. 带着access_token创建群聊，保存群聊id：
   文档地址：https://ding-doc.dingtalk.com/document#/org-dev-guide/create-chat

/**
 1. 创建群聊
 2. @param userId 群主id
 3. @param memberList 群成员ids
 4. @param chatroomName 群聊名称
 5. @param token token值
 6. @return 群聊id
 */
public String createChatroom(String userId, List<String> memberList,String chatroomName,String token){
    String chatroomId = "";
    try{
        DingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/chat/create");
        OapiChatCreateRequest req = new OapiChatCreateRequest();
        req.setName(chatroomName);
        req.setOwner(userId);
        req.setUseridlist(memberList);
        OapiChatCreateResponse rsp = client.execute(req, token);
        chatroomId = rsp.getChatid();//获取到群聊id
        return chatroomId;
    }catch (Exception e){
        log.info("钉钉异常" + e);
    }
    return chatroomId;
}

4. 根据群聊id，按照自己所需要格式发送消息：
   文档地址：https://ding-doc.dingtalk.com/document#/org-dev-guide/send-chat-messages

/**
 * 发送群消息
 * @param chatId 群聊id
 * @param content 发送内容
 * @param msgType 内容类型
 * @param token token值
 * @return 发送状态码
 */
public String sendMessage(String chatId,String content,String msgType,String token){
    String msg="";
    try {
        DingTalkClient client = new DefaultDingTalkClient("https://oapi.dingtalk.com/chat/send");
        OapiChatSendRequest req = new OapiChatSendRequest();
        req.setChatid(chatId);
        OapiChatSendRequest.Msg obj1 = new OapiChatSendRequest.Msg();
        OapiChatSendRequest.Text obj2 = new OapiChatSendRequest.Text();
        obj2.setContent(content);
        obj1.setText(obj2);
        obj1.setMsgtype(msgType);
        req.setMsg(obj1);
        OapiChatSendResponse rsp = client.execute(req, token);
        return rsp.getErrorCode();
    }catch (Exception e){
        log.info("钉钉异常" + e);
    }
    return msg;
}

注意事项：

1.提示访问ip不在白名单的时候：

2.获取AppKey和AppSecret的文档地址：https://ding-doc.dingtalk.com/doc#/serverapi2/eev437

对接钉钉企业内部outgoing机器人通知：

1.官方客服给予的JAVA代码（亲测可用，其中的appSecret修改为自己的）：

@Controller
public class BotController {
@RequestMapping(value = "/robot",method = RequestMethod.POST)
public void robot(HttpServletRequest request, HttpServletResponse response,
@RequestBody(required = false) JSONObject json) throws NoSuchAlgorithmException, IOException, InvalidKeyException, ApiException {
response.setContentType("text/html; charset=utf-8");
//请求header中的timestamp
String headerTimestamp = request.getHeader("timestamp");

//请求header中的sign
String headerSign = request.getHeader("sign");
//从请求body中可以获取到@机器人时的消息内容
System.out.println(json.getJSONObject("text").getString("content"));
System.out.println(json);
//当前机器人的webHook地址
String webHook = json.getString("sessionWebhook");

//计算签名值
String timestamp = headerTimestamp;
String appSecret = "zNyI0MqeEjxUqXYeGn_WlcynPNmmC0bW0m7i3xDCftA6R5jYl2hjZiu-VHjjEbqK";//当前企业内部机器人应用的appSecret值
String stringToSign = timestamp + "\n" + appSecret;
Mac mac = Mac.getInstance("HmacSHA256");
mac.init(new SecretKeySpec(appSecret.getBytes("UTF-8"), "HmacSHA256"));
byte[] signData = mac.doFinal(stringToSign.getBytes("UTF-8"));
String sign = new String(Base64.encodeBase64(signData));

//判断计算得到的签名与request中的签名是否一致
if (sign.equals(headerSign)){
//计算的签名与header中的签名值一致，可以响应
	DingTalkClient client = new DefaultDingTalkClient(webHook+"×tamp="+headerTimestamp+"&sign="+sign);
	OapiRobotSendRequest webhookRequest = new OapiRobotSendRequest();
	//可以根据需求使用不同的响应消息格式，目前支持text、markdown、actionCard、feedCard这4种消息类型
	// webhookRequest.setMsgtype("text");
	// OapiRobotSendRequest.Text text = new OapiRobotSendRequest.Text();
	// text.setContent("测试文本消息");
	// webhookRequest.setText(text);
	// OapiRobotSendRequest.At at = new OapiRobotSendRequest.At();
	// at.setAtMobiles(Arrays.asList("132xxxxxxxx"));
	// isAtAll类型如果不为Boolean，请升级至最新SDK
	// at.setIsAtAll(false);
	// webhookRequest.setAt(at);

	webhookRequest.setMsgtype("actionCard");
	OapiRobotSendRequest.Actioncard actioncard = new OapiRobotSendRequest.Actioncard();
	actioncard.setSingleURL("http://www.dingtalk.com");
	actioncard.setSingleTitle("按钮");
	actioncard.setTitle("测试消息");
	actioncard.setText("haha@18537608557");
	OapiRobotSendRequest.At at = new OapiRobotSendRequest.At();
	at.setAtMobiles(Arrays.asList("18537608557"));
	at.setIsAtAll(false);
	webhookRequest.setAt(at);
	webhookRequest.setActionCard(actioncard);

	OapiRobotSendResponse webhookResponse = client.execute(webhookRequest);
}else {
	//计算的签名与header中的签名不一致，不响应
	System.out.println("非法请求");
	}
}

2.本地测试，切记开启本地内网穿透：
①钉钉提供的内网穿透github地址，https://github.com/open-dingtalk/pierced，拉取可用
Windows启动命令：ding.exe -config=ding.cfg -subdomain=xiaomge 89

3.设置机器人的消息接收地址：

4.切记群机器人不是拉进群，是通过添加智能群助手
