Java 序列化和反序列化实例详解
在分布式应用中，对象只有经过序列化才能在各个分布式组件之间传输，这就涉及到两个方面的技术-发送者将对象序列化，接受者将对象反序列化，下面就是一个很好的例子！
1.实体-Employee
import java.io.Serializable;
public class Employee implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
private String name;
private int age;
}
2.SerializeHelper
import java.io.ByteArrayInputStream;
import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.ObjectInputStream;
import java.io.ObjectOutputStream;
public class SerializeHelper {
public byte[] Serialize(Object object) {
ByteArrayOutputStream byteArrayOutputStream = new ByteArrayOutputStream();
try {
ObjectOutputStream objectOutputStream = new ObjectOutputStream(byteArrayOutputStream);
//将对象写入到字节数组中进行序列化
objectOutputStream.writeObject(object);
return byteArrayOutputStream.toByteArray();
} catch (IOException e) {
e.printStackTrace();
}
return null;
}
public Object deSerialize(byte[] bytes) {
//将二进制数组导入字节数据流中
ByteArrayInputStream byteArrayInputStream = new ByteArrayInputStream(bytes);
try {
//将字节数组流转化为对象
ObjectInputStream objectInputStream = new ObjectInputStream(byteArrayInputStream);
return objectInputStream.readObject();
} catch (IOException e) {
e.printStackTrace();
} catch (ClassNotFoundException e) {
e.printStackTrace();
}
return null;
}
}
3.测试类
public class Hello {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
SerializeHelper serializeHelper = new SerializeHelper();
Employee employee = new Employee();
employee.setName("admin");
employee.setAge(20);
byte[] serializObject = serializeHelper.Serialize(employee);
System.out.println(serializObject);
Employee e = (Employee)serializeHelper.deSerialize(serializObject);
System.out.println("Name: " + e.getName()+",Age: " + e.getAge());
}
}
4.输出
[B@e05d173 Name: admin,Age: 20
5.总结
序列化和反序列化还有其他的框架可以完成，比如Hession，有机会再研究！
