使用java zip 压缩单个文件

import java.util.zip.ZipOutputStream;

import java.io.IOException;

import java.util.zip.ZipEntry;

import java.io.FileOutputStream;

import java.io.FileInputStream;

class CSVZip {

public static void Zip(String file,String zipfile) {

try {

//创建文件输入流对象

FileInputStream in = new FileInputStream(file); //0

//创建文件输出流对象

FileOutputStream out = new FileOutputStream(zipfile); //1

//创建ZIP数据输出流对象

ZipOutputStream zipOut = new ZipOutputStream(out);

//创建指向压缩原始文件的入口

ZipEntry entry = new ZipEntry(file); //0

zipOut.putNextEntry(entry);

//向压缩文件中输出数据

int nNumber;

byte[] buffer = new byte[512];

while ( (nNumber = in.read(buffer)) != -1)

zipOut.write(buffer, 0, nNumber);

//关闭创建的流对象

zipOut.close();

out.close();

in.close();

}catch (IOException e) {

System.out.println(e);

}

}

}
