java代码：对接飞书接口进行批量数据推送代码，推送的参数根据不同的用户来生成

好的，下面是对接飞书接口进行批量数据推送的Java代码示例，推送的参数根据不同的用户来生成：

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.apache.http.HttpResponse;
import org.apache.http.HttpStatus;
import org.apache.http.client.methods.HttpPost;
import org.apache.http.entity.ContentType;
import org.apache.http.entity.StringEntity;
import org.apache.http.impl.client.CloseableHttpClient;
import org.apache.http.impl.client.HttpClients;

import com.alibaba.fastjson.JSONObject;

public class FeishuBatchPush {

    // 飞书应用的App ID和App Secret
    private static final String APP_ID = "your_app_id";
    private static final String APP_SECRET = "your_app_secret";

    // 获取飞书应用的Access Token的API
    private static final String ACCESS_TOKEN_API = "https://open.feishu.cn/open-apis/auth/v3/app_access_token/internal/";

    // 推送消息的API
    private static final String PUSH_API = "https://open.feishu.cn/open-apis/message/v4/batch_send/";

    public static void main(String[] args) {
        // 获取Access Token
        String accessToken = getAccessToken();

        // 构造消息体和要推送的用户列表
        Map<String, JSONObject> messages = new HashMap<String, JSONObject>();
        List<String> userIds = new ArrayList<String>();
        messages.put("user_id_1", generateMessage("user_id_1"));
        userIds.add("user_id_1");
        messages.put("user_id_2", generateMessage("user_id_2"));
        userIds.add("user_id_2");
        messages.put("user_id_3", generateMessage("user_id_3"));
        userIds.add("user_id_3");

        // 批量推送消息
        batchPush(accessToken, messages, userIds);
    }

    // 获取Access Token
    private static String getAccessToken() {
        String accessToken = null;
        try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
            HttpPost httpPost = new HttpPost(ACCESS_TOKEN_API);
            httpPost.setHeader("Content-Type", "application/json");
            StringEntity requestEntity = new StringEntity("{\"app_id\":\"" + APP_ID + "\",\"app_secret\":\"" + APP_SECRET + "\"}", ContentType.APPLICATION_JSON);
            httpPost.setEntity(requestEntity);
            HttpResponse response = httpClient.execute(httpPost);
            if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                JSONObject responseBody = JSONObject.parseObject(EntityUtils.toString(response.getEntity()));
                accessToken = responseBody.getString("app_access_token");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        return accessToken;
    }

    // 构造要推送的消息体
    private static JSONObject generateMessage(String userId) {
        JSONObject message = new JSONObject();
        message.put("msg_type", "text");
        JSONObject content = new JSONObject();
        content.put("text", "Hello, " + userId);
        message.put("content", content);
        return message;
    }

    // 批量推送消息
    private static void batchPush(String accessToken, Map<String, JSONObject> messages, List<String> userIds) {
        try (CloseableHttpClient httpClient = HttpClients.createDefault()) {
            HttpPost httpPost = new HttpPost(PUSH_API);
            httpPost.setHeader("Content-Type", "application/json");
            httpPost.setHeader("Authorization", "Bearer " + accessToken);
            JSONObject postData = new JSONObject();
            postData.put("user_ids", userIds);
            postData.put("msg", messages);
            StringEntity requestEntity = new StringEntity(postData.toJSONString(), ContentType.APPLICATION_JSON);
            httpPost.setEntity(requestEntity);
            HttpResponse response = httpClient.execute(httpPost);
            if (response.getStatusLine().getStatusCode() == HttpStatus.SC_OK) {
                System.out.println("Batch push succeeded.");
            } else {
                System.out.println("Batch push failed.");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
    }

}

其中，需要将`your_app_id`和`your_app_secret`替换为自己的应用ID和应用密钥。在`generateMessage`方法中，可以根据不同的用户来生成不同的消息内容。在`batchPush`方法中，将要推送的消息体放入`messages`中，将要推送的用户ID放入`userIds`中即可进行批量推送。在代码执行完成后，可以在飞书中查看已推送的消息。
