learning java transient 自定义序例化

public class Person
    implements java.io.Serializable
{
    private String name;
    private transient int age;
    // 注意此处没有提供无参数的构造器!
    public Person(String name, int age)
    {
        System.out.println("有参数的构造器");
        this.name = name;
        this.age = age;
    }
    // 省略name与age的setter和getter方法

    // name的setter和getter方法
    public void setName(String name)
    {
        this.name = name;
    }
    public String getName()
    {
        return this.name;
    }

    // age的setter和getter方法
    public void setAge(int age)
    {
        this.age = age;
    }
    public int getAge()
    {
        return this.age;
    }
}

 

TransientTest

public class TransientTest
{
	public static void main(String[] args)
	{
		try (
			// 创建一个ObjectOutputStream输出流
			var oos = new ObjectOutputStream(new FileOutputStream("transient.txt"));
			// 创建一个ObjectInputStream输入流
			var ois = new ObjectInputStream(new FileInputStream("transient.txt")))
		{
			var per = new Person("孙悟空", 500);
			// 系统会per对象转换字节序列并输出
			oos.writeObject(per);
			var p = (Person) ois.readObject();
              //notes: p.getAge == 0 System.out.println(p.getAge()); } catch (Exception ex) { ex.printStackTrace(); } } }
