使用java检索mongodb数组元素

import com.mongodb.MongoClient;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import org.bson.Document;

// 创建MongoClient实例
MongoClient mongoClient = new MongoClient("localhost", 27017);

// 连接到数据库
MongoDatabase database = mongoClient.getDatabase("your_database_name");

MongoCollection<Document> collection = database.getCollection("your_collection_name");

import com.mongodb.client.model.Filters;

// 创建查询条件
Document query = new Document("your_array_field", new Document("$elemMatch", new Document("your_field", "your_value")));

// 执行查询
List<Document> results = collection.find(query).into(new ArrayList<>());

// 处理查询结果
for (Document result : results) {
    // 处理每个结果
}

mongoClient.close();
