使用java驱动程序检查mongo DB中的索引创建进度

import com.mongodb.MongoClient;
import com.mongodb.MongoClientURI;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoCursor;

import org.bson.Document;

public class MongoDBIndexChecker {

    public static void main(String[] args) {
        // 连接到MongoDB数据库
        MongoClientURI connectionString = new MongoClientURI("mongodb://localhost:27017");
        MongoClient mongoClient = new MongoClient(connectionString);
        
        // 获取MongoDB数据库中的集合
        MongoDatabase database = mongoClient.getDatabase("your_database_name");
        MongoCollection<Document> collection = database.getCollection("your_collection_name");
        
        // 获取集合的索引信息
        MongoCursor<Document> indexCursor = collection.listIndexes().iterator();
        
        // 检查索引创建进度
        while (indexCursor.hasNext()) {
            Document indexInfo = indexCursor.next();
            String indexName = indexInfo.getString("name");
            boolean isIndexCreating = indexInfo.getBoolean("inProgress", false);
            
            if (isIndexCreating) {
                System.out.println("索引 " + indexName + " 正在创建中...");
            } else {
                System.out.println("索引 " + indexName + " 已创建完成。");
            }
        }
        
        // 关闭MongoDB连接
        mongoClient.close();
    }
