ZipInputStream解压含有中文名称文件的zip包

1.重建zip包 

新建一个自己的zip包(也就是自己建立一个package)，比如com.agile.zip，在这个包中把要用到的类从jdk的源码里放到这里，用eclipse可以很同快地完成这 个工作。需要所类 有:DeflaterOutputStream,InflaterInputStream,ZipConstants,ZipEntry,ZipInputStream,ZipOutputStream

上面这些类在放到com.aigle.zip包中后，在Eclipse中会显示出一些错误，这里要做得就是更改import以及其它一些工作，惟一的目的就是通过编译，不再出现编译错误。 

2.修改ZipInputStream 

ZipInputStream这个类中，需要修改getUTF8String这个方法，经过试验，用winRar压缩后的zip文件，其中的中文文件名是以gbk编码保存的，因此只需要在这个方法的前面加上 

try { 
    String s = newString(b,off,len,"gbk"); 
    return s; 
   } catch (UnsupportedEncodingExceptione) { 
    e.printStackTrace(); 
   } 
修改后的方法类似下面的代码: 

private static String getUTF8String(byte[] b, intoff, int len) { 
   try { 
    String s = newString(b,off,len,"gbk"); 
    return s; 
   } catch (UnsupportedEncodingExceptione) { 
    e.printStackTrace(); 
   } 
   // First, count the number ofcharacters in the sequence 
   int count = 0; 
   int max = off + len; 

... 

... 

} 

3.去掉一些本地调用方法 

原来的java.util.zip.ZipEntry里面，要加载本地库，在这里这些代码是没有用处的，去掉就可以了，而如果不去掉，会引起链接错误，很奇怪，这几个native方法我也没有找到在哪儿使用了，sun的jdk1.4.2里留着它们做什么呢？ 

static { 
        /* loadthe zip library */ 
java.security.AccessController.doPrivileged( 
    newsun.security.action.LoadLibraryAction("zip")); 
initIDs(); 
    } 

 

然后就大功告成了。哈哈！
