【java】对象序列化Serializable、transient

 package 对象序列化;

 import java.io.Serializable;

 @SuppressWarnings("serial")
 class A implements Serializable{

 }
 public class TestSerializable {
     public static void main(String[] args) {

     }
 }

对象序列化：java.io.ObjectOutputStream

对象反序列化：java.io.ObjectInputStream

 package 对象序列化;

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

 @SuppressWarnings("serial")
 class A implements Serializable{
     private String name;
     private transient int age;//transient修饰的成员不能被序列化
     public A(String name,int age){
         this.name=name;
         this.age=age;
     }
     @Override
     public String toString() {
         return "name="+name+",age="+age;
     }
 }
 public class TestSerializable {
     public static void main(String[] args) throws FileNotFoundException, IOException, ClassNotFoundException {
         ObjectOutputStream oos=new ObjectOutputStream(new FileOutputStream(new File("D:"+File.separator+"A.ser")));
         oos.writeObject(new A("张三",23));
         oos.close();

         ObjectInputStream ois=new ObjectInputStream(new FileInputStream(new File("D:"+File.separator+"A.ser")));
         A a=(A)ois.readObject();
         ois.close();
         System.out.println(a);
     }
 }
