網(wǎng)上查了許久，最后發(fā)現(xiàn)三種不錯的方法：

1、jdk自帶的包java.util.zip.ZipOutputStream，不足之處，文件（夾）名稱帶中文時，

出現(xiàn)亂碼問題，實現(xiàn)代碼如下：

/**
? * 功能：把 sourceDir 目錄下的所有文件進(jìn)行 zip 格式的壓縮，保存為指定 zip 文件
? * @param sourceDir 如果是目錄，eg：D:\\MyEclipse\\first\\testFile，則壓縮目錄下所有文件；
? * ?????如果是文件，eg：D:\\MyEclipse\\first\\testFile\\aa.zip，則只壓縮本文件
? * @param zipFile 最后壓縮的文件路徑和名稱,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 {
???// 創(chuàng)建寫出流操作
???OutputStream os = new FileOutputStream(zipFile);
???BufferedOutputStream bos = new BufferedOutputStream(os);
???zos = new ZipOutputStream(bos);
???
???String basePath = null;
???
???// 獲取目錄
???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 源文件
? * @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、使用org.apache.tools.zip.ZipOutputStream，代碼如下，

Java代碼：

package?net.szh.zip; ??

??

import?java.io.BufferedInputStream; ??

import?java.io.File; ??

import?java.io.FileInputStream; ??

import?java.io.FileOutputStream; ??

import?java.util.zip.CRC32; ??

import?java.util.zip.CheckedOutputStream; ??

??

import?org.apache.tools.zip.ZipEntry; ??

import?org.apache.tools.zip.ZipOutputStream; ??

??

public?class?ZipCompressor?{ ??

????static?final?int?BUFFER?=?8192; ??

??

????private?File?zipFile; ??

??

????public?ZipCompressor(String?pathName)?{ ??

????????zipFile?=?new?File(pathName); ??

????} ??

??

????public?void?compress(String?srcPathName)?{ ??

????????File?file?=?new?File(srcPathName); ??

????????if?(!file.exists()) ??

????????????throw?new?RuntimeException(srcPathName?+?"不存在！"); ??

????????try?{ ??

????????????FileOutputStream?fileOutputStream?=?new?FileOutputStream(zipFile); ??

????????????CheckedOutputStream?cos?=?new?CheckedOutputStream(fileOutputStream, ??

????????????????????new?CRC32()); ??

????????????ZipOutputStream?out?=?new?ZipOutputStream(cos); ??

????????????String?basedir?=?""; ??

????????????compress(file,?out,?basedir); ??

????????????out.close(); ??

????????}?catch?(Exception?e)?{ ??

????????????throw?new?RuntimeException(e); ??

????????} ??

????} ??

??

????private?void?compress(File?file,?ZipOutputStream?out,?String?basedir)?{ ??

????????/*?判斷是目錄還是文件?*/??

????????if?(file.isDirectory())?{ ??

????????????System.out.println("壓縮："?+?basedir?+?file.getName()); ??

????????????this.compressDirectory(file,?out,?basedir); ??

????????}?else?{ ??

????????????System.out.println("壓縮："?+?basedir?+?file.getName()); ??

????????????this.compressFile(file,?out,?basedir); ??

????????} ??

????} ??

??

????/**?壓縮一個目錄?*/??

????private?void?compressDirectory(File?dir,?ZipOutputStream?out,?String?basedir)?{ ??

????????if?(!dir.exists()) ??

????????????return; ??

??

????????File[]?files?=?dir.listFiles(); ??

????????for?(int?i?=?0;?i?<?files.length;?i++)?{ ??

????????????/*?遞歸?*/??

????????????compress(files[i],?out,?basedir?+?dir.getName()?+?"/"); ??

????????} ??

????} ??

??

????/**?壓縮一個文件?*/??

????private?void?compressFile(File?file,?ZipOutputStream?out,?String?basedir)?{ ??

????????if?(!file.exists())?{ ??

????????????return; ??

????????} ??

????????try?{ ??

????????????BufferedInputStream?bis?=?new?BufferedInputStream( ??

????????????????????new?FileInputStream(file)); ??

????????????ZipEntry?entry?=?new?ZipEntry(basedir?+?file.getName()); ??

????????????out.putNextEntry(entry); ??

????????????int?count; ??

????????????byte?data[]?=?new?byte[BUFFER]; ??

????????????while?((count?=?bis.read(data,?0,?BUFFER))?!=?-1)?{ ??

????????????????out.write(data,?0,?count); ??

????????????} ??

????????????bis.close(); ??

????????}?catch?(Exception?e)?{ ??

????????????throw?new?RuntimeException(e); ??

????????} ??

????} ??

}?

?

3、可以用ant中的org.apache.tools.ant.taskdefs.Zip來實現(xiàn)，更加簡單。
Java代碼

package?net.szh.zip; ??

??

import?java.io.File; ??

??

import?org.apache.tools.ant.Project; ??

import?org.apache.tools.ant.taskdefs.Zip; ??

import?org.apache.tools.ant.types.FileSet; ??

??

public?class?ZipCompressorByAnt?{ ??

??

????private?File?zipFile; ??

??

????public?ZipCompressorByAnt(String?pathName)?{ ??

????????zipFile?=?new?File(pathName); ??

????} ??

???? ??

????public?void?compress(String?srcPathName)?{ ??

????????File?srcdir?=?new?File(srcPathName); ??

????????if?(!srcdir.exists()) ??

????????????throw?new?RuntimeException(srcPathName?+?"不存在！"); ??

???????? ??

????????Project?prj?=?new?Project(); ??

????????Zip?zip?=?new?Zip(); ??

????????zip.setProject(prj); ??

????????zip.setDestFile(zipFile); ??

????????FileSet?fileSet?=?new?FileSet(); ??

????????fileSet.setProject(prj); ??

????????fileSet.setDir(srcdir); ??

????????//fileSet.setIncludes("**/*.java");?包括哪些文件或文件夾?eg:zip.setIncludes("*.java"); ??

????????//fileSet.setExcludes(...);?排除哪些文件或文件夾 ??

????????zip.addFileset(fileSet); ??

???????? ??

????????zip.execute(); ??

????} ??

}??

測試一下
Java代碼

package?net.szh.zip; ??

??

public?class?TestZip?{ ??

????public?static?void?main(String[]?args)?{ ??

????????ZipCompressor?zc?=?new??ZipCompressor("E:\\szhzip.zip"); ??

????????zc.compress("E:\\test"); ??

???????? ??

????????ZipCompressorByAnt?zca?=?new?ZipCompressorByAnt("E:\\szhzipant.zip"); ??

????????zca.compress("E:\\test"); ??

????} ??

}?
