解压缩包

上传压缩包，并获取各个文件的文件名称

java 代码

public class UpLoadMoreFile
        extends ActionSupport
{
    private File upload;

    private List listDirectories;

    public String execute()
            throws Exception
    {
        ZipFile z1 = new ZipFile(upload);
        Enumeration emun = z1.entries();
        //目录名称的集合
        List listZip = new ArrayList();
        ZipEntry str = null;
        while (emun.hasMoreElements()) {
            ZipEntry entry = (ZipEntry) emun.nextElement();
            if (!entry.isDirectory()) {
                str = (ZipEntry) emun.nextElement();
                listZip.add(entry.getName());
            }
        }
        listDirectories = listZip;
        return SUCCESS;
    }
}

 

解压缩，并获取文件在硬盘的具体的url

java 代码

public class UploadMoreProfileAction
        extends ActionSupport
{
    private File upload;

    public String execute()
            throws Exception
    {
        ProfileManager manager = BeanLookup.getInstance().lookup(ProfileManager.class);
        ZipFile z1 = new ZipFile(upload);
        Enumeration emun = z1.entries();
        while (emun.hasMoreElements()) {
            ZipEntry entry = (ZipEntry) emun.nextElement();
            if (!entry.isDirectory()) {
                File file = readFile(z1, entry);
                //通过文件在硬盘的具体url获取文件里的具体信息
                UaProfile profile = manager.fetchProfile(file.toURL());

            }
        }
        return SUCCESS;
    }

    private File readFile(ZipFile z1, ZipEntry entry)
            throws Exception
    {
        InputStream in = z1.getInputStream(entry);
        File file = File.createTempFile(String.valueOf(System.currentTimeMillis()), "tmp");
        file.deleteOnExit();
        FileWriter fw = new FileWriter(file);

        BufferedReader br = new BufferedReader(new InputStreamReader(in));
        String line = null;
        while ((line = br.readLine()) != null) {
            fw.write(line);
        }
        fw.flush();
        fw.close();
        return file;
    }


    public File getUpload()
    {
        return upload;
    }

    public void setUpload(File upload)
    {
        this.upload = upload;
    }
}
