认识 transient !
作用：
transient关键字修改的变量不会被序列化！package discovery.transientTest;
import java.io.Serializable;
public class Transient implements Serializable{
private static final long serialVersionUID = 1L;
private transient int i = 0;
private int j = 0;
public Transient(int i,int j){
this.i = i;
this.j = j;
}
public String toString(){
return "i = " + i + ", j = " + j;
}
}package discovery.transientTest;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
/**
* 被transient修饰的变量不能被序列化
*/
public class Client {
public static void main(String[] args) throws Exception {
Client tt = new Client();
tt.test();
}
public void test() throws Exception {
Transient ti = new Transient(4, 5);
System.out.println(ti.toString());
ObjectOutputStream o = new ObjectOutputStream(new FileOutputStream("D:/ti.out"));
o.writeObject(ti);
o.close();
ObjectInputStream in =new ObjectInputStream(new FileInputStream("D:/ti.out"));
Transient logInfo = (Transient)in.readObject();
System.out.println(logInfo.toString());
}
}输出：
i = 4, j = 5
i = 0, j = 5
