Java代码如何实现Object转byte[]及byte[]转Object呢？

 对象和数组之间互转的实现思路:
     使用ObjectOutputStream 和
	 ObjectInputStream
	 对象即可实现数组和对象互转的效果
 

package com.java265.utils;   
  
import java.io.ByteArrayInputStream;   
import java.io.ByteArrayOutputStream;   
import java.io.IOException;   
import java.io.ObjectInputStream;   
import java.io.ObjectOutputStream;   
  
import com.java265.javabean.TestBean;   
  
public class ObjectAndByte {   
  
    /**  
     * 对象转数组  
     * @param obj  
     * @return  
     */  
    public byte[] toByteArray (Object obj) {      
        byte[] bytes = null;      
        ByteArrayOutputStream bos = new ByteArrayOutputStream();      
        try {        
            ObjectOutputStream oos = new ObjectOutputStream(bos);         
            oos.writeObject(obj);        
            oos.flush();         
            bytes = bos.toByteArray ();      
            oos.close();         
            bos.close();        
        } catch (IOException ex) {        
            ex.printStackTrace();   
        }      
        return bytes;    
    }   
       
    /**  
     * 数组转对象  
     * @param bytes  
     * @return  
     */  
    public Object toObject (byte[] bytes) {      
        Object obj = null;      
        try {        
            ByteArrayInputStream bis = new ByteArrayInputStream (bytes);        
            ObjectInputStream ois = new ObjectInputStream (bis);        
            obj = ois.readObject();      
            ois.close();   
            bis.close();   
        } catch (IOException ex) {        
            ex.printStackTrace();   
        } catch (ClassNotFoundException ex) {        
            ex.printStackTrace();   
        }      
        return obj;    
    }   
       
    public static void main(String[] args) {   
        TestBean tb = new TestBean();   
        tb.setName("maomao");   
        tb.setValue("1232442424");   
           
        ObjectAndByte oa = new ObjectAndByte();   
        byte[] b = oa.toByteArray(tb);   
        System.out.println(new String(b));   
           
        System.out.println("=======================================");   
           
        TestBean teb = (TestBean) oa.toObject(b);   
        System.out.println(teb.getName());   
        System.out.println(teb.getValue());   
    }   
}  

package com.java265.javabean; 
  
import java.io.Serializable;   
  
public class TestBean implements Serializable{   
  
    private String name;   
       
    private String value;   
  
    public String getName() {   
        return name;   
    }   
  
    public void setName(String name) {   
        this.name = name;   
    }   
  
    public String getValue() {   
        return value;   
    }   
  
    public void setValue(String value) {   
        this.value = value;   
    }       
}
