如何将序列化的对象压缩到文件中

仅使用“ GZIPOutputStream ”进行数据压缩。

FileOutputStream fos = new FileOutputStream("c:\\address.gz");
GZIPOutputStream gz = new GZIPOutputStream(fos);
ObjectOutputStream oos = new ObjectOutputStream(gz);

GZIP示例

在此示例中，您将创建一个“地址”对象，将其压缩并将其写入文件“ c：\\ address.gz ”。

PS Address对象可以参考本文 。

package com.mkyong.io;
 
import java.io.FileOutputStream;
import java.io.ObjectOutputStream;
import java.io.Serializable;
import java.util.zip.GZIPOutputStream;
 
public class Serializer implements Serializable{
 
   public static void main (String args[]) {
    
	   Serializer serializer = new Serializer();
	   serializer.serializeAddress("wall street", "united state");
   }
 
   public void serializeAddress(String street, String country){
	   
	   Address address = new Address();
	   address.setStreet(street);
	   address.setCountry(country);
	   
	   try{
		   
		   FileOutputStream fos = new FileOutputStream("c:\\address.gz");
		   GZIPOutputStream gz = new GZIPOutputStream(fos);
 
		   ObjectOutputStream oos = new ObjectOutputStream(gz);
		   
		   oos.writeObject(address);
		   oos.close();
		   
		   System.out.println("Done");
		   
	   }catch(Exception ex){
		   ex.printStackTrace();
	   }	 
   }
}
