JAVA
最近因为项目的需要,要做一个打包下载..而java提供的java.util.zip.*.......对中文不支持...反来到网上看了一下..要修改java的原代码..而无意之间又发现了ant的打包,直接支持中文打包..当时乐得...下面就是一个简单的例子,注 需要导入ant.jar支持包.
package cn.edu.cuit.disasterSystem.web.struts2.action;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileOutputStream;
import org.apache.tools.zip.ZipOutputStream;
