Java代码中解压RAR文件
- import java.io.File;
- import java.io.FileOutputStream;
- import de.innosystec.unrar.Archive;
- import de.innosystec.unrar.rarfile.FileHeader;
- public class UnRARTools {
- public void unrar(File sourceRar, File destDir) throws Exception {
- Archive archive = null;
- FileOutputStream fos = null;
- System.out.println("Starting...");
- try {
- archive = new Archive(sourceRar);
- FileHeader fh = archive.nextFileHeader();
- int count = 0;
- File destFileName = null;
- while (fh != null) {
- System.out.println((++count) + ") " + fh.getFileNameString());
- String compressFileName = fh.getFileNameString().trim();
- destFileName = new File(destDir.getAbsolutePath() + "/" + compressFileName);
- if (fh.isDirectory()) {
