java zip压缩

写了个用java zip压缩的功能，可以实现对文件和目录的压缩。

由于java.util.zip.ZipOutputStream有中文乱码问题，所以采用org.apache.tools.zip.ZipOutputStream。
以下是代码：
Java代码 
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) {  
        /* 判断是目录还是文件 */ 
        if (file.isDirectory()) {  
            System.out.println("压缩：" + basedir + file.getName());  
            this.compressDirectory(file, out, basedir);  
        } else {  
            System.out.println("压缩：" + basedir + file.getName());  
            this.compressFile(file, out, basedir);  
        }  
    }  
 
    /** 压缩一个目录 */ 
    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++) {  
            /* 递归 */ 
            compress(files[i], out, basedir + dir.getName() + "/");  
        }  
    }  
 
    /** 压缩一个文件 */ 
    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);  
        }  
    }  
} 

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) {
  /* 判断是目录还是文件 */
  if (file.isDirectory()) {
   System.out.println("压缩：" + basedir + file.getName());
   this.compressDirectory(file, out, basedir);
  } else {
   System.out.println("压缩：" + basedir + file.getName());
   this.compressFile(file, out, basedir);
  }
 }

 /** 压缩一个目录 */
 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++) {
   /* 递归 */
   compress(files[i], out, basedir + dir.getName() + "/");
  }
 }

 /** 压缩一个文件 */
 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);
  }
 }
}

后来发现原来可以用ant中的org.apache.tools.ant.taskdefs.Zip来实现，更加简单。
Java代码 
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夹 eg:zip.setIncludes("*.java");  
        //fileSet.setExcludes(...); 排除哪些文件或文件夹  
        zip.addFileset(fileSet);  
          
        zip.execute();  
    }  
} 

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夹 eg:zip.setIncludes("*.java");
  //fileSet.setExcludes(...); 排除哪些文件或文件夹
  zip.addFileset(fileSet);
  
  zip.execute();
 }
}
测试一下
Java代码 
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");  
    }  
}
