Java中压缩与解压--中文文件名乱码解决办法
----------------------------------------------------------------------
Apache Ant有个包专门处理ZIP文件，可以指定文件名的编码方式。由此可以解决问题。
例如：用ls.zip.ZipOutputStream代替java.util.zip.ZipOutputStream。
------------------------------------------------------------------------
java对於文字的编码是以 unicode为基础，因此，若是以ZipInputStream及ZipOutputStream来处理压缩及解压缩的工作，碰到中文档名或路径，那当然是以unicode来处理罗！但是，现在市面上的压缩及解压缩软体，例如winzip，却是不支援unicode的，一碰到档名以unicode编码的档案，它就不处理。 那要如何才能做出让WinRar能够处理的压缩档呢？那就得从修改ZipInputStream及ZipOutputStream对於档名的编码方式来着手了。我们可以从jdk的src.zip取得ZipInputStream及ZipOutputStream的原始码来加以修改
一、ZipOutputStream.java
1.从jdk的src.zip取得ZipOutputStream.java原始码，另存到一个新文件中，档名改为CnZipOutputStream.java。
2.开始修改原始码，将class名称改为CnZipOutputStream
3.建构式也必须更改为CnZipOutputStream
4.新增member，这个member记录编码方式
private String encoding="UTF-8";
5.再新增一个建构式(这个建构式可以让这个class在new的时候，设定档名的编码)
public CZipOutputStream(OutputStream out,String encoding) {
this(out);
}
6.到byte[] nameBytes = getUTF8Bytes(e.name);(有二个地方)，将它修改如下：
byte[] nameBytes = null;
赵本山杀人被抓
try
{
if (UpperCase().equals("UTF-8"))
nameBytes =getUTF8Bytes(e.name);
else
nameBytes= ding);
}
catch(Exception byteE)
{
nameBytes=getUTF8Bytes(e.name);
}
二、ZipInputStream.java
1.从jdk的src.zip取得ZipInputStream.java原始码，另存到一个新文件中，档名改为CnZipInputStream.java。
2.开始修改原始码，将class名称改为CnZipInputStream
3.建构式也必须更改为CnZipInputStream
4.新增member，这个member记录编码方式
private String encoding="UTF-8";
5.再新增一个建构式如下(这个建构式可以让这个class在new的时候，设定档名的编码)
public CZipInputStream(InputStream in,String encoding) {
this(in);
}
6.到ZipEntry e = createZipEntry(getUTF8String(b, 0, len))；这一行，将它改成如下：
ZipEntry e=null;
try
{
if (UpperCase().equals("UTF-8"))
e=createZipEntry(getUTF8String(b, 0, len));
else
e=createZipEntry(new String(b,0,ding));
}
catch(Exception byteE)
{
e=createZipEntry(getUTF8String(b, 0, len));
}
以上两个档案储存後compile产生CZipOutputStream.class及CZipInputStream.class，使用winzip开启 [java_home]\jre\lib\rt.jar这
个档案，将CnZipOutputStream.class及 CnZipInputStream.class加进去，以後当压缩及解压缩时有中文档名及路径的问题时，就可以指定编码方式来处理了。
使用方法:
CnZipOutputStream zos=new CnZipOutputStream(OutputStream os,String encoding);
CnZipInputStream zins=new CnZipInputStream(InputStream ins,String encoding);
对于前面文章中文件打包下载中遇到的中文文件问题，解决手法是:
OutputStream os = OutputStream();
CnZipOutputStream zos = new CnZipOutputStream(os,"gbk"); //加上中文编码类型
Properties Properties();
Iterator it=properties.keySet().iterator();
while (it.hasNext())菊麟
{
String ().toString();
String Property(key);
System.out.println(key+"=="+value);鼓励人坚强的话
