Java Zip檔案解壓縮

　　真實無語了，絕大多數是不能用的。這可能跟我的開發環境有關吧。

　　我用的是ubuntu14.04，eclipse 用的是sts3.5,jdk81.8.0_20

　　經過兩天的努力檢驗了無數的code終于讓我找到一個還能用的可以解決中文亂碼問題。

　　這個項目用maven建構的依賴jar坐标如下

　　<!-- 用于zip檔案解壓縮 -->

　　<dependency>

　　<groupid>ant</groupid>

　　<artifactid>ant</artifactid>

　　<version>1.7.0</version>

　　</dependency>

　　代碼如下：

package com.uujava.mbfy.test;

import java.io.fileinputstream;

import java.io.fileoutputstream;

import java.io.ioexception;

import java.io.inputstream;

import org.apache.tools.zip.zipoutputstream;

* 尚須解決bug:

* 這裡采用寫死這定檔案編碼，是否有辦法讀取壓縮檔案時判斷起内部檔案名編碼。
