如何在java中将实现org.apache.geode.pdx.PdxSerializable的对象存储在文件中

import org.apache.geode.pdx.PdxReader;
import org.apache.geode.pdx.PdxSerializable;
import org.apache.geode.pdx.PdxWriter;

public class MyPdxSerializable implements PdxSerializable {
    private String name;
    private int age;

    // 省略构造函数和其他方法

    @Override
    public void toData(PdxWriter writer) {
        writer.writeString("name", name);
        writer.writeInt("age", age);
    }

    @Override
    public void fromData(PdxReader reader) {
        name = reader.readString("name");
        age = reader.readInt("age");
    }
}

import org.apache.geode.cache.Region;
import org.apache.geode.cache.client.ClientCache;

public class Main {
    public static void main(String[] args) {
        // 创建一个ClientCache实例
        ClientCache cache = new ClientCacheFactory().create();

        // 获取一个Region对象
        Region<String, MyPdxSerializable> region = cache.getRegion("myRegion");

        // 创建一个MyPdxSerializable对象
        MyPdxSerializable obj = new MyPdxSerializable("John", 25);

        // 将对象存储到Region中
        region.put("key", obj);

        // 关闭ClientCache实例
        cache.close();
    }
}
