压缩根文件夹内容而不在zip文件中使用root

我有以下文件夹结构:

RootFolder
|
|
| -->F1-->F1.1-->t1.txt,t2.txt
  -->F2-->F2.2-->t3.txt

我使用以下代码成功获取以下zip文件:

result.zip - >包含:

RootFolder
|
|
| -->F1-->F1.1-->t1.txt,t2.txt
  -->F2-->F2.2-->t3.txt

我需要创建一个包含整个“RootFolder”内容的zip文件,而不创建根文件夹“RootFolder”;

我的意思是我需要结果如下:

result.zip - >包含:

|
|
| -->F1-->F1.1-->t1.txt,t2.txt
  -->F2-->F2.2-->t3.txt
public static void main(String[] args) throws Exception {
    zipFolder("c:/new/RootFolder", "c:/new/result.zip");
}


static public void zipFolder(String srcFolder, String destZipFile)
throws IOException, FileNotFoundException {
    ZipOutputStream zip = null;
    FileOutputStream fileWriter = null;

    fileWriter = new FileOutputStream(destZipFile);
    zip = new ZipOutputStream(fileWriter);

    addFolderToZip("", srcFolder, zip);
    zip.flush();
    zip.close();
}

static private void addFileToZip(String path, String srcFile,
        ZipOutputStream zip) throws IOException, FileNotFoundException {

    File folder = new File(srcFile);
    if (folder.isDirectory()) {
        addFolderToZip(path, srcFile, zip);
    } else {
        byte[] buf = new byte[1024];
        int len;
        FileInputStream in = new FileInputStream(srcFile);
        zip.putNextEntry(new ZipEntry(path + "/" + folder.getName()));
        while ((len = in.read(buf)) > 0) {
            zip.write(buf, 0, len);
        }
        in.close();
    }
}

    static public void addFolderToZip(String path, String srcFolder,
            ZipOutputStream zip) throws IOException, FileNotFoundException {
        File folder = new File(srcFolder);

        for (String fileName : folder.list()) 

{
        if (path.equals("")) {
            addFileToZip(folder.getName(), srcFolder + "/" + fileName, zip);
        } else {
            addFileToZip(path + "/" + folder.getName(), srcFolder + "/"
                    + fileName, zip);
        }
    }
}

您需要做的是添加文件,不是以您的根文件夹开头,而是以其内容开头。

类似的东西:

filelist = getFileList(rootFolder)  
foreach(File f : filelist){  
    addFolderToZip(f)
}

对于伪代码抱歉,不记得原来的功能名称,现在无法检查它们,但可以轻松用Google搜索。

重点是跳过在根文件夹的存档中创建文件夹。

我已经编写了一些实用程序方法,使用NIO File API将目录复制到Zip文件(该库是开源的):

的Maven:

<dependency>  
    <groupId>org.softsmithy.lib</groupId>  
    <artifactId>softsmithy-lib-core</artifactId>  
    <version>0.3</version>  
</dependency>

API:CopyFileVisitor.copy

我试图找出解决问题的最简单方法。 我解决了这个问题,只需删除根目录名,同时使用以下命令保存在zip文件中:

String pathAfterOmittingtheRootFolder=path.replace(ROOT_FOLDER_NAME, "");

完整的方法是:

static private void addFileToZip(String path, String srcFile,
        ZipOutputStream zip,String exportedRootDirectory) throws IOException, FileNotFoundException {

    File folder = new File(srcFile);
    if (folder.isDirectory()) {

    addFolderToZip(path, srcFile, zip,exportedRootDirectory);
} else {
    byte[] buf = new byte[1024];
    int len;
    FileInputStream in = new FileInputStream(srcFile);
    String pathAfterOmittingtheRootFolder=path.replaceFirst(exportedRootDirectory, "");
    zip.putNextEntry(new ZipEntry(pathAfterOmittingtheRootFolder + "/" + folder.getName()));
    while ((len = in.read(buf)) > 0) {
        zip.write(buf, 0, len);
    }
    in.close();
}

}
