java 用ant进行zip解压

利用ant进行zip解压，非常简单

import org.apache.tools.ant.Project;
import org.apache.tools.ant.taskdefs.Expand;  

  public void testUnZip() {
        String unZipFile =
            "F:/OMSInstall201108150953_windows_release/packages/sso.zip";
        String saveZipFilePath = "D:/testzip";
        File srcdir = new File(unZipFile);
        if (!srcdir.exists()) {
           System.out.println("The '" + unZipFile + "' file ile does not exist.");
            return;
        }
        File saveZipFile = new File(saveZipFilePath);
        if (!saveZipFile.exists()) {
            saveZipFile.mkdirs();
        }
        Project prj1 = new Project();
        Expand expand = new Expand();
        expand.setProject(prj1);
        expand.setSrc(new File(unZipFile));
        expand.setOverwrite(true);// 是否覆盖
        File f = new File(saveZipFilePath);
        expand.setDest(f);
        expand.execute();
    }

    public void testzip() {
        String zipFilePath= "D:/testzip";
        String saveZipFilePath =  "D:/sso.zip";
        File srcdir = new File(zipFilePath);
        if (!srcdir.exists()) {
            return;
        }
        File zipFile = new File(saveZipFilePath);
        Project prj = new Project();
        Zip zip = new Zip();
        zip.setProject(prj);
        zip.setDestFile(zipFile);
        FileSet fileSet = new FileSet();
        fileSet.setProject(prj);
        fileSet.setDir(srcdir);
        zip.addFileset(fileSet);
        zip.execute();
    }
