Java使用winrar解压缩

JAVA JDK中的解压缩似乎不能解压缩我们手工压缩的RAR文件，只能解压JDK中的API压缩的RAR

所以想出以下用WINRAR命令行方式的解压缩

package edu.nwpu.vcampus.util; import java.io.File; public class ZipUtil { public static final String winrarPath = "C://Program Files//WinRAR//WinRAR.exe"; public static boolean unzip(String zipFile) { boolean bool = false; File f=new File(zipFile); if(!f.exists()) { return false; } String folder = f.getParent(); System.out.println(folder); String cmd = winrarPath + " X " + zipFile + " "+folder; //cmd="C://Program Files//WinRAR//WinRAR.exe X D://a.rar D://a"; System.out.println(cmd); try { Process proc = Runtime.getRuntime().exec(cmd); if (proc.waitFor() != 0) { if (proc.exitValue() == 0) { bool = false; } } else { bool = true; } } catch (Exception e) { e.printStackTrace(); } return bool; } public static boolean unzip(String zipFile,String password) { boolean bool = false; File f=new File(zipFile); if(!f.exists()) { return false; } String folder = f.getParent(); System.out.println(folder); String cmd = winrarPath + " X -p " + password+" "+zipFile + " "+folder; //cmd="C://Program Files//WinRAR//WinRAR.exe X D://a.rar D://a"; System.out.println(cmd); try { Process proc = Runtime.getRuntime().exec(cmd); if (proc.waitFor() != 0) { if (proc.exitValue() == 0) { bool = false; } } else { bool = true; } } catch (Exception e) { e.printStackTrace(); } return bool; } public static void main(String[] args) { String zipFile = "D://a.rar"; boolean b = ZipUtil.unzip(zipFile); System.out.println(b); } }
