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;
     }
