这篇文章主要介绍了Java原生序列化和反序列化代码实例,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

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 [id=" + id + ", userName=" + userName + "]"; }}

工具类：

package com.nicchagil.nativeserialize;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;public class NativeSerializeTools { /** * 序列化 * @param filePath 序列化的路径 * @param s 序列化的对象 */ public static void write(String filePath, Serializable s) throws FileNotFoundException, IOException { if (filePath == null || filePath.length() == 0) { throw new RuntimeException("请传入序列化路径"); } if (s == null) { throw new RuntimeException("请传入序列化对象"); } File f = new File(filePath); ObjectOutputStream oos = null; FileOutputStream fos = null; try { fos = new FileOutputStream(f); oos = new ObjectOutputStream(fos); oos.writeObject(s); System.out.println("finish."); } finally { if (oos != null) { oos.close(); } if (fos != null) { fos.close(); } System.out.println("close the resource."); } } /** * 反序列化 * @param filePath 反序列化的路径 * @return 反序列化的对象 */ public static Object read(String filePath) throws ClassNotFoundException, FileNotFoundException, IOException { if (filePath == null || filePath.length() == 0) { throw new RuntimeException("请传入反序列化路径"); } File f = new File(filePath); ObjectInputStream ois = null; FileInputStream fis = null; Object o = null; try { fis = new FileInputStream(f); ois = new ObjectInputStream(fis); o = ois.readObject(); System.out.println("finish."); } finally { if (ois != null) { ois.close(); } if (fis != null) { fis.close(); } System.out.println("close the resource."); } return o; }}

测试类：

package com.nicchagil.nativeserialize;import java.io.FileNotFoundException;import java.io.IOException;import org.junit.Assert;import org.junit.Test;public class HowToUse { private User user = new User(100, "Nick Huang"); private String filePath = "d:/user.txt"; @Test public void c1() throws FileNotFoundException, IOException { NativeSerializeTools.write(filePath, user); } @Test public void c2() throws FileNotFoundException, IOException, ClassNotFoundException { Object o = NativeSerializeTools.read(filePath); System.out.println(o); Assert.assertTrue(user.equals(o)); }}

日志：

finish.
close the resource.
finish.
close the resource.
User [id=100, userName=Nick Huang]

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
