java删除文件及其目录

1.删除指定文件路径

public @ResponseBody
    String deleteFiles(HttpServletRequest request) {
        log.info(this.getClass().getSimpleName() + "."
                + Thread.currentThread().getStackTrace()[1].getMethodName()
                + "()------start");
        // 身份校验
        String random = request.getParameter("random");
        String checkCode = request.getParameter("checkCode");
        String reCheckCode=MD5Util.encrypt("pplovemm"+random.substring(random.length()-6));
        String result = "";
        if(reCheckCode.equals(checkCode)){ 
           // 指定路径文件
            String newFilePath="E:\video\2017-07-07\";
            log.info("Delete file or path:"+newFilePath);
            System.out.println("Delete file or path:"+newFilePath);
            if (newFilePath.startsWith(newFilePath) && clearFiles(newFilePath)) {
                result = "success";
            } else {
                result = "fail";
            }
            log.info(this.getClass().getSimpleName() + "."
                    + Thread.currentThread().getStackTrace()[1].getMethodName()
                    + "()--------end");
            return result;
        }else {
            result = "fail";
            log.info(this.getClass().getSimpleName() + "."
                    + Thread.currentThread().getStackTrace()[1].getMethodName()
                    + "()-身份校验失败--end");            
            return result;
        }        

2.clearFiles方法：

    // 删除文件和目录
    private static boolean clearFiles(String workspaceRootPath) {
        File file = new File(workspaceRootPath);
        if (file.exists()) {
            deleteFile(file);
        }
        // resources 文件夹被删除后需新建
        if (!file.exists() && workspaceRootPath.endsWith("resources")) {
            return file.mkdir();
        }else if(!file.exists()){
            return true;
        }
        return false;
    }
