Java中的transient关键字介绍

transient说明一个属性是临时的，不会被序列化。
下面是一个demo，name声明为 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("密码");
		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());
	}

}

输出结果：

null密码
