java实现序列化及反序列化

-例

1. 创建Student类

public class Student implements Serializable {
    private String name;
    private String sex;
    private Integer age;
    private String address;
    private String phone;

    public String getName() {
        return name;
    }

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

    public String getSex() {
        return sex;
    }

    public void setSex(String sex) {
        this.sex = sex;
    }

    public Integer getAge() {
        return age;
    }

    public void setAge(Integer age) {
        this.age = age;
    }

    public String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public String getPhone() {
        return phone;
    }

    public void setPhone(String phone) {
        this.phone = phone;
    }
}

2.创建SerializeTest类，实现对Student类的序列化及反序列化

public class SerializeTest {
    public static void main(String[] args) throws IOException {
        serialize();
        Student s = (Student) deserialize();
        System.out.println("姓名：" + s.getName() + "\n年龄：" + s.getAge() + "\n性别：" + s.getSex() + "\n地址：" + s.getAddress() + "\n手机：" + s.getPhone());
    }

    public static Object deserialize() throws IOException {
        Student s = new Student();
        File f = new File("D:/student.out");
        InputStream is = new FileInputStream(f);
        ObjectInputStream ois = null;
        try {
            ois = new ObjectInputStream(is);
        } catch (IOException e) {
            e.printStackTrace();
        }
        try {
            s = (Student) ois.readObject();
        } catch (IOException e) {
            e.printStackTrace();
        } catch (ClassNotFoundException e) {
            e.printStackTrace();
        }
        is.close();
        ois.close();
        return s;
    }

    public static void serialize() {
        Student s = new Student();
        s.setName("张三");
        s.setAge(32);
        s.setSex("man");
        s.setAddress("阜阳");
        s.setPhone("12345678910");
        OutputStream os = null;
        ObjectOutputStream oos = null;
        File f = new File("D:/student.out");
        try {
            os = new FileOutputStream(f);
            oos = new ObjectOutputStream(os);
            oos.writeObject(s);
        } catch (FileNotFoundException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        } finally {
            if (oos != null)
                try {
                    oos.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            if (os != null)
                try {
                    os.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
        }
    }
}
