java实现zip的压缩和解压(支持中文文件名)

用过java做压缩或解压的都知道，jdk提供的zip只能按UTF-8格式处理，所有jdk提供的zip不能支持中文文件名采用Apache的zip包解决中文文件名问题（依赖 ant-1.9.6.jar）

 测试：

package com.tzz.test.util;

import com.tzz.util.CHZipUtils;

public class CHZipUtilsTest {

	public static void main(String[] args) throws Exception {
//		String sourceFolder = "D:/test/1.txt";

		String unZipPath = "D:/test/unzip";
//		CHZipUtils.zip(sourceFolder, zipFilePath);
		CHZipUtils.unZip(zipFilePath, unZipPath);
		System.out.println("********执行成功**********");
