在mongodb中插入一个类型为Map的变量，并将Enum作为键

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

import java.util.EnumMap;
import java.util.Map;

enum Status {
    ACTIVE,
    INACTIVE,
    PENDING
}

public class MongoDBExample {
    public static void main(String[] args) {
        // 创建MongoDB客户端
        MongoClient mongoClient = MongoClients.create("mongodb://localhost:27017");
        // 获取数据库
        MongoDatabase database = mongoClient.getDatabase("testdb");
        // 获取集合
        MongoCollection<Document> collection = database.getCollection("testcollection");

        // 创建一个包含Enum键的Map
        Map<Status, String> statusMap = new EnumMap<>(Status.class);
        statusMap.put(Status.ACTIVE, "Active User");
        statusMap.put(Status.INACTIVE, "Inactive User");
        statusMap.put(Status.PENDING, "Pending User");

        // 将Map转换为Document
        Document document = new Document("statusMap", statusMap);

        // 插入文档
        collection.insertOne(document);

        // 关闭客户端
        mongoClient.close();
    }
}
