Java:对象到字节 [] 和字节 [] 到对象转换器(用于东京内阁) [英] Java: object to byte[] and byte[] to object converter (for Tokyo Cabinet)

问题描述

我需要将对象转换为 byte[] 以存储在 Tokyo Cabinet 键值存储中.从键值存储读取时，我还需要将 byte[] 取消字节到对象.

I need to convert objects to a byte[] to be stored in the Tokyo Cabinet key-value store. I also need to unbyte the byte[] to an Object when reading from the key-value store.

是否有任何软件包可以帮助我完成这项任务?或者自己实施它的最佳解决方案是什么?

Are there any packages out there that will help me with this task? Or would the best solution to implement it myself?

推荐答案

public static byte[] serialize(Object obj) throws IOException {
    ByteArrayOutputStream out = new ByteArrayOutputStream();
    ObjectOutputStream os = new ObjectOutputStream(out);
    os.writeObject(obj);
    return out.toByteArray();
}
public static Object deserialize(byte[] data) throws IOException, ClassNotFoundException {
    ByteArrayInputStream in = new ByteArrayInputStream(data);
    ObjectInputStream is = new ObjectInputStream(in);
    return is.readObject();
}
