Java implementation zip compressed file (i)

Online search for a long time, and finally found three kinds of good methods:

1, the JDK comes with the package java.util.zip.ZipOutputStream, the deficiency, the file (folder) name with Chinese,

There is a garbled problem, the implementation code is as follows:

/**
* Function: To compress all the files in the SourceDir directory in zip format, save as the specified zip file
* @param sourcedir If the directory, Eg:d:\\myeclipse\\first\\testfile, then compressed all the files in the directory;
* If it is a file, Eg:d:\\myeclipse\\first\\testfile\\aa.zip, only compress this file
* @param zipfile the last compressed file path and name, Eg:d:\\myeclipse\\first\\testfile\\aa.zip
*/
Public File Dozip (string sourcedir, String zipfilepath)
Throws IOException {

File File = new file (SourceDir);
File ZipFile = new file (Zipfilepath);
Zipoutputstream Zos = null;
try {
Create write Flow action
OutputStream OS = new FileOutputStream (ZipFile);
Bufferedoutputstream BOS = new Bufferedoutputstream (OS);
Zos = new Zipoutputstream (BOS);

String basepath = null;

Get directory
if (File.isdirectory ()) {
BasePath = File.getpath ();
}else {
BasePath = File.getparent ();
}

ZipFile (file, BasePath, Zos);
}finally {
if (Zos!= null) {
Zos.closeentry ();
Zos.close ();
}
}

return zipfile;
}

/**
* @param source file
* @param basepath
* @param Zos
*/
private void ZipFile (File source, String BasePath, Zipoutputstream Zos)
Throws IOException {
file[] files = null;
if (Source.isdirectory ()) {
Files = Source.listfiles ();
} else {
Files = new File[1];
Files[0] = source;
}

InputStream is = null;
String PathName;
byte[] buf = new byte[1024];
int length = 0;
try{
for (File file:files) {
if (File.isdirectory ()) {
PathName = File.getpath (). substring (basepath.length () + 1) + "/";
Zos.putnextentry (New ZipEntry (PathName));
ZipFile (file, BasePath, Zos);
}else {
PathName = File.getpath (). substring (basepath.length () + 1);
is = new FileInputStream (file);
Bufferedinputstream bis = new Bufferedinputstream (IS);
Zos.putnextentry (New ZipEntry (PathName));
while (length = Bis.read (buf)) > 0) {
Zos.write (buf, 0, length);
}
}
}
}finally {
if (is!= null) {
Is.close ();
}
}

}

2, the use of Org.apache.tools.zip.ZipOutputStream, code as follows, Java code:PackageNet.szh.zip;ImportJava.io.BufferedInputStream;ImportJava.io.File;ImportJava.io.FileInputStream;ImportJava.io.FileOutputStream;Importjava.util.zip.CRC32;ImportJava.util.zip.CheckedOutputStream;ImportOrg.apache.tools.zip.ZipEntry;ImportOrg.apache.tools.zip.ZipOutputStream; PublicclassZipcompressor {StaticFinalintBUFFER = 8192;PrivateFile ZipFile; PublicZipcompressor (String pathName) {ZipFile =NewFile (PathName); } PublicvoidCompress (String srcpathname) {File File =NewFile (Srcpathname);if(!file.exists ())ThrowNewRuntimeException (Srcpathname + "does not exist.) ");Try{FileOutputStream FileOutputStream =NewFileOutputStream (ZipFile); Checkedoutputstream cos =NewCheckedoutputstream (FileOutputStream,NewCRC32 ()); Zipoutputstream out =NewZipoutputstream (COS);                String basedir = "";                Compress (file, out, basedir);            Out.close (); }Catch(Exception e) {ThrowNewRuntimeException (e); }        }PrivatevoidCompress (file file, zipoutputstream out, String basedir) {/* To determine whether the directory or file */if(File.isdirectory ()) {System.out.println ("compression:" + Basedir + file.getname ()); This. compressdirectory (file, out, basedir); }Else{System.out.println ("compression:" + Basedir + file.getname ()); This. compressfile (file, out, basedir); }/** Compress a directory */PrivatevoidCompressdirectory (File dir, zipoutputstream out, String basedir) {if(!dir.exists ()) return; file[] files = dir.listfiles (); for(inti = 0; i < files.length;            i++) {* * recursive * * COMPRESS (files[i], out, Basedir + dir.getname () + "/"); }/** Compress a file */PrivatevoidCompressfile (file file, zipoutputstream out, String basedir) {if(!file.exists ()) { return; }Try{Bufferedinputstream bis =NewBufferedinputstream (NewFileInputStream (file)); ZipEntry entry =NewZipEntry (Basedir + file.getname ()); Out.putnextentry (entry);intCountbyteData[] =Newbyte[BUFFER]; while((count = bis.read (data, 0, BUFFER)!=-1)                {out.write (data, 0, count);            } bis.close (); }Catch(Exception e) {ThrowNewRuntimeException (e); }        }    }

3, can use Ant in the Org.apache.tools.ant.taskdefs.Zip to realize, more simple.
Java codePackageNet.szh.zip;ImportJava.io.File;ImportOrg.apache.tools.ant.Project;ImportOrg.apache.tools.ant.taskdefs.Zip;ImportOrg.apache.tools.ant.types.FileSet; Publicclasszipcompressorbyant {PrivateFile ZipFile; PublicZipcompressorbyant (String pathName) {ZipFile =NewFile (PathName); } PublicvoidCompress (String srcpathname) {File Srcdir =NewFile (Srcpathname);if(!srcdir.exists ())ThrowNewRuntimeException (Srcpathname + "does not exist.)                        "); Project PRJ =NewProject (); Zip zip =NewZip ();            Zip.setproject (PRJ);            Zip.setdestfile (ZipFile); Fileset Fileset =NewFileset ();            Fileset.setproject (PRJ);            Fileset.setdir (Srcdir); Fileset.setincludes ("**/*.java");            Include which files or folders eg:zip.setIncludes ("*.java"); Fileset.setexcludes (...);                        Exclude which files or folders zip.addfileset (Fileset);        Zip.execute (); }} Test
Java codePackageNet.szh.zip; PublicclassTestzip { PublicStaticvoidMain (string[] args) {Zipcompressor ZC =NewZipcompressor ("E:\\szhzip.zip");                        Zc.compress ("E:\\test"); Zipcompressorbyant Zca =NewZipcompressorbyant ("E:\\szhzipant.zip");        Zca.compress ("E:\\test"); }    }
