我已成功编辑 jar 文件并将其按原样包装回来......使用以下代码
public void run() throws IOException
{
Manifest manifest = new Manifest();
manifest.getMainAttributes().put(Attributes.Name.MANIFEST_VERSION, "1.0");
// JarOutputStream target = new JarOutputStream(new FileOutputStream("E:\\hiren1\\WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar"), manifest);
// add(new File("E:\\hiren1\\WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz/"), target);
JarOutputStream target = new JarOutputStream(new FileOutputStream("C:\\Users\\bhavik.kama\\Desktop\\Sphinx\\sphinx4-1.0beta6-bin\\sphinx4-1.0beta6\\modified_jar_dict\\WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar"), manifest);
add(new File("C:\\Users\\bhavik.kama\\Desktop\\Sphinx\\sphinx4-1.0beta6-bin\\sphinx4-1.0beta6\\modified_jar_dict\\WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz/"), target);
target.close();
}
private void add(File source, JarOutputStream target) throws IOException
{
BufferedInputStream in = null;
try
{
if (source.isDirectory())
{
//String name = source.getPath().replace("\\", "/");
if(isFirst)
{
firstDir = source.getParent() + "\\";
isFirst = false;
}
String name = source.getPath();
name = name.replace(firstDir,"");
if (!name.isEmpty())
{
if (!name.endsWith("/"))
name += "/";
JarEntry entry = new JarEntry(name);
entry.setTime(source.lastModified());
target.putNextEntry(entry);
target.closeEntry();
}
for (File nestedFile: source.listFiles())
add(nestedFile, target);
return;
}
String name = source.getPath();
name = name.replace(firstDir,"").replace("\\", "/");
//JarEntry entry = new JarEntry(source.getPath().replace("\\", "/"));
JarEntry entry = new JarEntry(name);
//JarEntry entry = new JarEntry(source.getName());
entry.setTime(source.lastModified());
target.putNextEntry(entry);
in = new BufferedInputStream(new FileInputStream(source));
byte[] buffer = new byte[1024];
while (true)
{
int count = in.read(buffer);
if (count == -1)
break;
target.write(buffer, 0, count);
}
target.closeEntry();
}
finally
{
if (in != null)
in.close();
}
}
