transient解釋一個屬性是暫時的，不會被序列化。
上面是一個Demo，name聲明為 transient，不被序列化

package com.zzs.tet;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.ObjectInput;
import java.io.ObjectInputStream;
import java.io.ObjectOutput;
import java.io.ObjectOutputStream;
import java.io.Serializable;

public class TransientDemo implements Serializable{
  /**
	 * 
	 */
	private static final long serialVersionUID = 1L;
	private transient String name;
  private String password;
  
	public String getName() {
		return name;
	}

	public void setName(String name) {
		this.name = name;
	}

	public String getPassword() {
		return password;
	}

	public void setPassword(String password) {
		this.password = password;
	}

	/**
	 * @param args
	 * @throws IOException 
	 * @throws FileNotFoundException 
	 * @throws ClassNotFoundException 
	 */
	public static void main(String[] args) throws FileNotFoundException, IOException, ClassNotFoundException {
		// TODO Auto-generated method stub
		String path="D:"+File.separator+"object.txt";
		File file=new File(path);
		TransientDemo transientDemo=new TransientDemo();
		transientDemo.setName("姓名");
		transientDemo.setPassword("暗碼");
		ObjectOutput output=new ObjectOutputStream(new FileOutputStream(file));
		output.writeObject(transientDemo);
		ObjectInput input=new ObjectInputStream(new FileInputStream(file));
		TransientDemo demo=(	TransientDemo )input.readObject();
		System.out.println(demo.getName()+demo.getPassword());
	}

}

輸入成果：
