Java 压缩,解压zip文件(支持中文)

JDK自带了zip相关的api,但遗憾的是,如果zip文件中有包含中文名的文件,就报错无法处理,所以,我这里的例子并没有用jdk的api,而是用了apache的ant包。
apache ant下载地址:
http://ant.apache.org/bindownload.cgi
把lib/ant.jar放到我们项目的构建路径中,只需要ant.jar。其实ant的zip API与jdk的高度相似,如果之前是用jdk的api写的,基本上只要更改顶部的import包就可以了

				String fileName=entry.getName().toLowerCase();
				if(!fileName.startsWith("__macosx/")&&fileName.endsWith("psd"))

					//如果文件名没有以__macosx/开头,且以psd结尾,就是psd文件,解压,在mac下压缩的文件,会自动加上__macosx目录,但其实是没用的
