【Java】Java原生的序列化和反序列化

写一个Java原生的序列化和反序列化的DEMO。

 

需序列化的类：

package com.nicchagil.nativeserialize;

import java.io.Serializable;

public class User implements Serializable {

    private static final long serialVersionUID = 1L;

    private Integer id;
    private String userName;
    
    public User(Integer id, String userName) {
        super();
        this.id = id;
        this.userName = userName;
    }

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public String getUserName() {
        return userName;
    }

    public void setUserName(String userName) {
        this.userName = userName;
    }

    public static long getSerialversionuid() {
        return serialVersionUID;
    }

    @Override
    public int hashCode() {
        final int prime = 31;
        int result = 1;
        result = prime * result + ((id == null) ? 0 : id.hashCode());
        result = prime * result
                + ((userName == null) ? 0 : userName.hashCode());
        return result;
    }

    @Override
    public boolean equals(Object obj) {
        if (this == obj)
            return true;
        if (obj == null)
            return false;
        if (getClass() != obj.getClass())
            return false;
        User other = (User) obj;
        if (id == null) {
            if (other.id != null)
                return false;
        } else if (!id.equals(other.id))
            return false;
        if (userName == null) {
            if (other.userName != null)
                return false;
        } else if (!userName.equals(other.userName))
            return false;
        return true;
    }

    @Override
    public String toString() {
        return "User [>;
    }

}
