Java，复制文件夹及所有子文件，并排重

直接复制下面代码即可，可直接使用

public static void moveFile(String orgin_path, String moved_path) {
        File[] files = new File(orgin_path).listFiles();
        for (File file : files) {
            if (file.isFile()) {// 如果是文件
                File movedFile = new File(moved_path + File.separator + file.getName());
                  // 如果文件已经存在则跳过
                if (movedFile.exists()) {
                    System.out.println("文件已经存在1：" + file.getAbsolutePath());
                    System.out.println("文件已经存在2：" + movedFile.getAbsolutePath());
                    continue;
                } else {
                    // 否则复制
                    try {
                        FileUtil.copyFile(file, movedFile);
                    } catch (Exception e) {
                        e.printStackTrace();
                    }
                }
            }
            if (file.isDirectory()) {// 如果是目录,就递归
                String childMPath = moved_path + File.separator + file.getName();
                new File(childMPath).mkdir();
                moveFile(file.getAbsolutePath(), childMPath);
            }
        } 
    }

    public static void copyFile(File resource, File target) throws Exception {
        FileInputStream inputStream = new FileInputStream(resource);
        BufferedInputStream bufferedInputStream = new BufferedInputStream(inputStream);
        FileOutputStream outputStream = new FileOutputStream(target);
        BufferedOutputStream bufferedOutputStream = new BufferedOutputStream(outputStream);
        byte[] bytes = new byte[1024 * 2];
        int len = 0;
        while ((len = inputStream.read(bytes)) != -1) {
            bufferedOutputStream.write(bytes, 0, len);
        }
        bufferedOutputStream.flush();
        bufferedInputStream.close();
        bufferedOutputStream.close();
        inputStream.close();
        outputStream.close();
        long end = System.currentTimeMillis();
    }
