你可以用:

org . apache commons。我deleteQuietly (destFile FileUtils);

删除文件，从不抛出异常。如果file是目录，请删除该目录及其所有子目录。 File.delete()和这个方法的区别是: 待删除的目录不需要为空目录。 当无法删除文件或目录时，不会抛出异常。

没有Commons IO和< Java SE 7

public static void deleteRecursive(File path){
            path.listFiles(new FileFilter() {
                @Override
                public boolean accept(File pathname) {
                    if (pathname.isDirectory()) {
                        pathname.listFiles(this);
                        pathname.delete();
                    } else {
                        pathname.delete();
                    }
                    return false;
                }
            });
            path.delete();
        }

public static void deleteDirectory(File path) 
{
    if (path == null)
        return;
    if (path.exists())
    {
        for(File f : path.listFiles())
        {
            if(f.isDirectory()) 
            {
                deleteDirectory(f);
                f.delete();
            }
            else
            {
                f.delete();
            }
        }
        path.delete();
    }
}

番石榴21.0及以上版本

有一个void deleterecursive (Path Path, RecursiveDeleteOption…)options)会抛出从Guava 21.0开始可用的MoreFiles类的IOException静态方法。

请参阅Javadoc文档:

public static void deleteRecursively(Path path, RecursiveDeleteOption... options) throws IOException Deletes the file or directory at the given path recursively. Deletes symbolic links, not their targets (subject to the caveat below). If an I/O exception occurs attempting to read, open or delete any file under the given directory, this method skips that file and continues. All such exceptions are collected and, after attempting to delete all files, an IOException is thrown containing those exceptions as suppressed exceptions.

在Java 7+中，你可以使用Files类。代码非常简单:

Path directory = Paths.get("/tmp");
Files.walkFileTree(directory, new SimpleFileVisitor<Path>() {
   @Override
   public FileVisitResult visitFile(Path file, BasicFileAttributes attrs) throws IOException {
       Files.delete(file);
       return FileVisitResult.CONTINUE;
   }

   @Override
   public FileVisitResult postVisitDirectory(Path dir, IOException exc) throws IOException {
       Files.delete(dir);
       return FileVisitResult.CONTINUE;
   }
});

您应该查看Apache的commons-io。它有一个FileUtils类，可以做你想做的事情。

FileUtils.deleteDirectory(new File("directory"));
