Java implementation Zip compressed file

Find these kinds of methods on the Internet, feel good, collect them, convenient for everyone to use

• JDK comes with the package java.util.zip.ZipOutputStream, shortcomings, file (folder) name with Chinese, garbled problem occurs, the implementation code is as follows

/*** Function: Compress all files in SourceDir directory into zip format, save as specified zip file *@paramSourceDir If it is a directory, Eg:d:\\myeclipse\\first\\testfile, all files under the compressed directory; * If it is a file, eg:d:\\myeclipse\\first\\testfile\\ Aa.zip, only the file is compressed *@paramZipFile the last compressed file path and name, Eg:d:\\myeclipse\\first\\testfile\\aa.zip*/  PublicFile dozip (String sourcedir, string zipfilepath)throwsIOException {File file=NewFile (SourceDir); File ZipFile=NewFile (Zipfilepath); Zipoutputstream Zos=NULL; Try {   //creating a write-out flow operationOutputStream OS =NewFileOutputStream (ZipFile); Bufferedoutputstream Bos=Newbufferedoutputstream (OS); Zos=NewZipoutputstream (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 (); }  }    returnZipFile;} /**   * @paramSource file *@paramBasePath *@paramZos*/ Private voidZipFile (File source, String BasePath, Zipoutputstream Zos)throwsIOException {file[] files=NULL; if(Source.isdirectory ()) {Files=Source.listfiles (); } Else{Files=NewFile[1]; files[0] =source; } InputStream is=NULL;  String PathName; byte[] buf =New byte[1024]; intLength = 0; Try{    for(File file:files) {if(File.isdirectory ()) {PathName= File.getpath (). substring (basepath.length () + 1) + "/"; Zos.putnextentry (NewZipEntry (pathName));    ZipFile (file, BasePath, Zos); }Else{pathName= File.getpath (). substring (basepath.length () + 1); is=Newfileinputstream (file); Bufferedinputstream bis=NewBufferedinputstream (IS); Zos.putnextentry (NewZipEntry (pathName));  while(length = Bis.read (buf)) > 0) {zos.write (buf,0, length); }    }   }  }finally {   if(Is! =NULL) {is.close (); }  } }

• Using Org.apache.tools.zip.ZipOutputStream, the code is as follows

 Public classZipcompressor {Static Final intBUFFER = 8192; PrivateFile ZipFile;  Publiczipcompressor (String pathName) {ZipFile=NewFile (pathName); }          Public voidCompress (String srcpathname) {File file=NewFile (srcpathname); if(!file.exists ())Throw NewRuntimeException (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) {Throw NewRuntimeException (e); }       }         Private voidCompress (file file, zipoutputstream out, String basedir) {/*determine whether a directory or a 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*/      Private voidcompressdirectory (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*/      Private voidcompressfile (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); intcount; byteData[] =New byte[BUFFER];  while(count = bis.read (data, 0, BUFFER))! =-1) {out.write (data,0, Count);           } bis.close (); } Catch(Exception e) {Throw NewRuntimeException (e); }       }   } 

• Can be implemented using ORG.APACHE.TOOLS.ANT.TASKDEFS.ZIP in Ant, which is much simpler

 Public classZipcompressorbyant {PrivateFile ZipFile;  Publiczipcompressorbyant (String pathName) {ZipFile=NewFile (pathName); }               Public voidCompress (String srcpathname) {File Srcdir=NewFile (srcpathname); if(!srcdir.exists ())Throw NewRuntimeException (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"), including which files or folders eg:zip.setIncludes ("*.java"); //fileset.setexcludes (...); exclude which files or foldersZip.addfileset (Fileset);       Zip.execute (); }} Test the Java code PackageNet.szh.zip;  Public classTestzip { Public Static voidMain (string[] args) {zipcompressor Zc=NewZipcompressor ("E:\\szhzip.zip"); Zc.compress ("E:\\test"); Zipcompressorbyant Zca=NewZipcompressorbyant ("E:\\szhzipant.zip"); Zca.compress ("E:\\test"); }   }
