import org.mongodb.morphia.annotations.Entity;
import org.mongodb.morphia.annotations.Id;

import java.util.ArrayList;
import java.util.HashMap;

@Entity("data")
public class Data {
    @Id
    private String id;
    private HashMap<String, String> hashMap;
    private ArrayList<String> arrayList;

    // 省略构造函数、getter和setter方法
}

import com.mongodb.MongoClient;
import org.mongodb.morphia.Datastore;
import org.mongodb.morphia.Morphia;

public class Main {
    public static void main(String[] args) {
        // 连接MongoDB数据库
        MongoClient mongoClient = new MongoClient("localhost", 27017);

        // 创建Morphia实例
        Morphia morphia = new Morphia();

        // 将要映射的类注册到Morphia中
        morphia.map(Data.class);

        // 创建Datastore实例，用于执行数据库操作
        Datastore datastore = morphia.createDatastore(mongoClient, "your_database_name");

        // 存储数据
        Data data = new Data();
        data.setHashMap(new HashMap<>());
        data.getHashMap().put("key1", "value1");
        data.getHashMap().put("key2", "value2");
        data.setArrayList(new ArrayList<>());
        data.getArrayList().add("item1");
        data.getArrayList().add("item2");

        datastore.save(data);
    }
}
