java zip 文件名乱码 java文件名字乱码

最近发现Java原生的Zip压缩组件在压缩过程中，不支持文件名的中文编码，会在压缩过程中把中文文件名变成乱码。Apache的ant包中的压缩组件修复了这个问题，如果你在使用压缩功能时需要支持中文文件名，建议你直接使用Apache的压缩组件来实现这个功能。

具体使用方法：

1.在你的pom文件中增加对Apache的ant工具包的dependency：

org.apache.ant

ant

1.9.3

并在头部引用用到的类：

import org.apache.tools.zip.ZipEntry;

import org.apache.tools.zip.ZipFile;

import org.apache.tools.zip.ZipOutputStream;

2.压缩的方法实现，大家注意，本组件支持设置编码(setEncoding("GBK")方法)，解决了中文编码的问题：

public static void compress(String srcPath , String dstPath) throws IOException{
File srcFile = new File(srcPath);
File dstFile = new File(dstPath);
if (!srcFile.exists()) {
throw new FileNotFoundException(srcPath + "does not exists");
}
FileOutputStream out = null;
ZipOutputStream zipOut = null;
try {
out = new FileOutputStream(dstFile);
zipOut = new ZipOutputStream(new BufferedOutputStream(out));
zipOut.setEncoding("GBK");
String baseDir = "";
compress(srcFile, zipOut, baseDir);
}
catch (Throwable ex){
throw new RuntimeException(ex);
}
finally {
if(null != zipOut){
zipOut.close();
out = null;
}
if(null != out){
out.close();
}
}
}
private static void compress(File file, ZipOutputStream zipOut, String baseDir) throws IOException{
if (file.isDirectory()) {
compressDirectory(file, zipOut, baseDir);
} else {
compressFile(file, zipOut, baseDir);
}
}
/** 压缩一个目录 */
private static void compressDirectory(File dir, ZipOutputStream zipOut, String baseDir) throws IOException{
File[] files = dir.listFiles();
for (int i = 0; i < files.length; i++) {
compress(files[i], zipOut, baseDir + dir.getName() + "/");
}
}
/** 压缩一个文件 */
private static void compressFile(File file, ZipOutputStream zipOut, String baseDir) throws IOException{
if (!file.exists()){
return;
}
BufferedInputStream bis = null;
try {
bis = new BufferedInputStream(new FileInputStream(file));
ZipEntry entry = new ZipEntry(baseDir + file.getName());
zipOut.putNextEntry(entry);
int count;
byte data[] = new byte[BUFFER];
while ((count = bis.read(data, 0, BUFFER)) != -1) {
zipOut.write(data, 0, count);
}
}finally {
if(null != bis){
bis.close();
}
}
}

3.解压缩的实现：

public static void decompress(String zipFile , String dstPath)throws IOException{
File pathFile = new File(dstPath);
if(!pathFile.exists()){
pathFile.mkdirs();
}
ZipFile zip = new ZipFile(zipFile);
for(Enumeration entries = zip.getEntries();entries.hasMoreElements();){
ZipEntry entry = (ZipEntry)entries.nextElement();
String zipEntryName = entry.getName();
InputStream in = null;
OutputStream out = null;
try{
in = zip.getInputStream(entry);
String outPath = (dstPath+"/"+zipEntryName).replaceAll("\\*", "/");;
//判断路径是否存在,不存在则创建文件路径
File file = new File(outPath.substring(0, outPath.lastIndexOf('/')));
if(!file.exists()){
file.mkdirs();
}
//判断文件全路径是否为文件夹,如果是上面已经上传,不需要解压
if(new File(outPath).isDirectory()){
continue;
}
out = new FileOutputStream(outPath);
byte[] buf1 = new byte[1024];
int len;
while((len=in.read(buf1))>0){
out.write(buf1,0,len);
}
}
finally {
if(null != in){
in.close();
}
if(null != out){
out.close();
}
}
}
}

以上代码经过测试，可以直接使用。
