java序列化

一. 描述

• 在网络通信和数据存储方面很有用
• 对于需要序列化的类，应该在其实现时在类头部加上implements Serializable

二. 示例

• 序列化

  public byte[] functionName (ClassType sample) {
      try {
          ByteArrayOutputStream baos = new ByteArrayOutputStream();
          ObjectOutputStream oos = new ObjectOutputStream(baos);
          oos.writeObject(sample);
          byte[] bytes = baos.toByteArray();
          System.out.println("...serialization complete."); 
          return bytes;
      } catch (Exception e) {
          System.out.println("...serialization failed.");
      }
      return null;
  }

• 反序列化

  public ClassType deserializeCFC(byte[] bytes) {
      try {
          ByteArrayInputStream bais = new ByteArrayInputStream(bytes);
          ObjectInputStream ois = new ObjectInputStream(bais);
          return (ClassType) ois.readObject();
      } catch (Exception e) {
          System.out.println("...deserialization failed.");
      }
      return null;
  }
