MongoDB Java 拉取

MongoDB是一种流行的开源NoSQL数据库，它以其灵活性、可扩展性和高性能而闻名。作为一个Java开发人员，我们可以使用Java驱动程序来与MongoDB进行交互，从而实现数据的存储、检索和处理。本文将向您介绍如何使用MongoDB Java驱动程序来拉取数据，并提供一个案例代码来帮助您更好地理解。

java
MongoClient mongoClient = new MongoClient("localhost", 27017);
MongoDatabase database = mongoClient.getDatabase("mydb");

java
MongoCollection collection = database.getCollection("mycollection");
FindIterable documents = collection.find();
for (Document document : documents) {
    System.out.println(document);
}

java
import com.mongodb.MongoClient;
import com.mongodb.client.FindIterable;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import org.bson.Document;
public class MongoDBExample {
    public static void main(String[] args) {
        MongoClient mongoClient = new MongoClient("localhost", 27017);
        MongoDatabase database = mongoClient.getDatabase("mydb");
        MongoCollection collection = database.getCollection("mycollection");
        FindIterable documents = collection.find();
        for (Document document : documents) {
            System.out.println(document);
        }
        mongoClient.close();
    }
}
