如何在java中读取MongoDB数组

<dependency>
    <groupId>org.mongodb</groupId>
    <artifactId>mongo-java-driver</artifactId>
    <version>3.12.10</version>
</dependency>

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

MongoClientURI uri = new MongoClientURI("mongodb://localhost:27017");
MongoClient mongoClient = new MongoClient(uri);
MongoDatabase database = mongoClient.getDatabase("your_database_name");

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

Document query = new Document("your_array_field", new Document("$exists", true));
MongoCursor<Document> cursor = collection.find(query).iterator();

while (cursor.hasNext()) {
    Document document = cursor.next();
    List<Object> array = (List<Object>) document.get("your_array_field");
    // 处理数组数据
    // ...
}

cursor.close();
