使用google云数据存储中的实体类从Kind中检索属性？

import com.google.cloud.datastore.Datastore;
import com.google.cloud.datastore.DatastoreOptions;
import com.google.cloud.datastore.Entity;
import com.google.cloud.datastore.Key;
import com.google.cloud.datastore.KeyFactory;
import com.google.cloud.datastore.Query;
import com.google.cloud.datastore.QueryResults;

public class DatastoreExample {
    private static final String KIND = "Person";

    public static void main(String[] args) {
        // 创建Datastore客户端
        Datastore datastore = DatastoreOptions.getDefaultInstance().getService();

        // 创建KeyFactory以便创建实体的Key
        KeyFactory keyFactory = datastore.newKeyFactory().setKind(KIND);

        // 创建查询对象
        Query<Entity> query = Query.newEntityQueryBuilder()
                .setKind(KIND)
                .setFilter(Query.PropertyFilter.eq("age", 25)) // 过滤条件：age等于25
                .build();

        // 执行查询并获取结果
        QueryResults<Entity> results = datastore.run(query);
        while (results.hasNext()) {
            Entity entity = results.next();
            System.out.println("Name: " + entity.getString("name"));
            System.out.println("Age: " + entity.getLong("age"));
        }
    }
}
