java - 如何使 BufferedInputStream 可序列化？

Question

我需要使 java BufferedInputStream 可序列化。是否有任何替代方案或任何其他方式来实现它？

您是否发现此实现中存在任何问题

import java.io.BufferedInputStream;
import java.io.InputStream;
import java.io.Serializable;

public class SerializableBufferedInputStream extends BufferedInputStream implements Serializable
{
  public SerializableBufferedInputStream(InputStream in)
  {
    super(in);
  }

  public SerializableBufferedInputStream(InputStream in, int size)
  {
    super(in, size);
  }
}

Answer 1

首先，BufferedInputStream 创建一个 BufferedInputStream 并将其参数(输入流)保存在其中，以供以后使用。但你说的是可序列化，这意味着将对象的状态转换为字节流那么为什么需要转换它呢？

这个东西可以帮助你检查(如果你想要其他的，请提供你的代码)

public class MainClass {

public static void main(String[] args) throws Exception {
    Punk obj1 = new Punk("A");
    Punk obj2 = new Punk("B");
    Punk obj3 = new Punk("V");
    ObjectOutputStream objectOut = new ObjectOutputStream(new BufferedOutputStream(
            new FileOutputStream("C:/punkObjects.bin")));

    objectOut.writeObject(obj1); // Write object
    objectOut.writeObject(obj2); // Write object
    objectOut.writeObject(obj3); // Write object
    objectOut.close(); // Close the output stream

    ObjectInputStream objectIn = null;
    int objectCount = 0;
    punk object = null;

    objectIn = new ObjectInputStream(new BufferedInputStream(new FileInputStream(
            "C:/punkObjects.bin")));

    // Read from the stream until we hit the end
    while (objectCount < 3) {
        object = (punk) objectIn.readObject();
        objectCount++;
        System.out.println(object);
    }

    objectIn.close();

}
}

class Punk implements Serializable {

String str;

public Punk(String s) {
    str = s;
}
}
