用Java實現zip壓縮檔和目錄程式碼（二）__Java

今天寫了個用java壓縮的功能，可以實現對檔案和目錄的壓縮。

由於java.util.zip.ZipOutputStream有中文亂碼問題，所以採用org.apache.tools.zip.ZipOutputStream。
以下是代碼：
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) {
/* 判斷是目錄還是檔案 */
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++) {
/* 遞迴 */
compress(files[i], out, basedir + dir.getName() + "/");
}
} /** 壓縮一個檔案 */
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) {
/* 判斷是目錄還是檔案 */
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++) {
/* 遞迴 */
compress(files[i], out, basedir + dir.getName() + "/");
}
} /** 壓縮一個檔案 */
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);
}
}
}

後來發現原來可以用ant中的org.apache.tools.ant.taskdefs.Zip來實現，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"); 包括哪些檔案或檔案夾 eg:zip.setIncludes("*.java");
//fileSet.setExcludes(...); 排除哪些檔案或檔案夾
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"); 包括哪些檔案或檔案夾 eg:zip.setIncludes("*.java");
//fileSet.setExcludes(...); 排除哪些檔案或檔案夾
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");
}
}
