Unzip a zip package with Chinese name files

When Java.util.zip.ZipInputStream and Java.util.zip.ZipOutputStream compress and decompress a zip package with a Chinese name file, the following exception is reported:

Java.lang.IllegalArgumentException
At Java.util.zip.ZipInputStream.getUTF8String (zipinputstream.java:293)
At Java.util.zip.ZipInputStream.readLOC (zipinputstream.java:247)
At Java.util.zip.ZipInputStream.getNextEntry (zipinputstream.java:74)
At Com.test.ZipTest.unZipAssetSouce (ziptest.java:25)
At Com.test.ZipTest.main (ziptest.java:14)

The reason is that the JDK comes with the zip utility class, the default read file name is UTF-8 encoding, and for those files with a UTF-8 encoded file will not be properly read, such as the use of WinZip compressed ZIP package will not be able to process a file with Chinese names, it uses ASCII-encoded, This problem is often encountered in development, and the following solutions are given:

Extracts several processing zip-related classes within the JDK, Deflater.java,deflateroutputstream.java,inflaterinputstream.java,zipconstants.java, Zipentry.java,zipinputstram.java, and then customize a Compresszzipfile.java read into the zip file, source code:

Import Java.io.BufferedInputStream;
Import Java.io.BufferedOutputStream;
Import Java.io.File;
Import Java.io.FileInputStream;

Import Java.io.FileOutputStream;
	public class Compresszzipfile {static final int BUFFER = 2048; /** * Read zip file, only suitable for the zip file is not valid for RAR files, because the zip file compression algorithm is public, and RAR is not * @version 1.0 * @param zipfilepath:zip file path, Unzippath: to extract to
			File path */public void Readzip (String zipfilepath,string unzippath) {try {bufferedoutputstream bos = null;
			Create input byte stream FileInputStream fis = new FileInputStream (Zipfilepath);
			Create an input character stream based on the input streams Bufferedinputstream bis = new Bufferedinputstream (FIS);
			Creates a zip file input stream Zipinputstream ZiS = new Zipinputstream (bis), based on character streams;
			ZIP file entry, representing the zip file ZipEntry entry;
				Iterates through the file entries, as long as they are not empty, while ((Entry=zis.getnextentry ())!=null) {System.out.println () ("= =" +entry.getname ());
				int count;
				byte date[] = new Byte[buffer];
				If the entry is a file directory, continue to execute if (entry.isdirectory ()) {continue; }else{int begin = ZipFilePath.lastindexof ("\") +1; int end = Zipfilepath.lastindexof (".")
					+1;
					String ziprealname = zipfilepath.substring (begin,end); BOS = new Bufferedoutputstream (new FileOutputStream (this.getrealfilename unzippath+ "\" +ziprealname,entry.getname (
					))));
					while ((Count=zis.read (date))!=-1) {bos.write (date,0,count);
				} bos.flush (); Bos.close ();
		} zis.close ();
		catch (Exception e) {e.printstacktrace (); } private File Getrealfilename (String zippath,string absfilename) {string[] dirs = Absfilename.split ("/", Absfilena
		Me.length ());
		Creates a file object, filename = new file (Zippath);  if (dirs.length>1) {for (int i=0;i<dirs.length-1;i++) {/////Create a new file object based on the file abstract path and dir path string, the path is the previous directory files =
			New File (File,dirs[i]);
		} if (!file.exists ()) {file.mkdirs ();
		File = new file (file,dirs[dirs.length-1]);
	return file; }
}

Then build a test class Ziptest.java, source code:

Import Com.zip.tool.CompresszZipFile;

public class Ziptest {public

	static void Main (String args[]) {
		
		Compresszzipfile compress = new Compresszzipfile () ;
		Compress. Readzip ("D:\\android\\workspace\\test\\word.zip", "d:\\test");
	}

Test run OK ...

To facilitate testing, the above related classes into a jar package to share to everyone. (Some of the above source sources from the network)
