java删除文件及其目录

1.删除指定文件路径

 1 public @ResponseBody
 2     String deleteFiles(HttpServletRequest request) {
 3         log.info(this.getClass().getSimpleName() + "."
 4                 + Thread.currentThread().getStackTrace()[1].getMethodName()
 5                 + "()------start");
 6         // 身份校验
 7         String random = request.getParameter("random");
 8         String checkCode = request.getParameter("checkCode");
 9         String reCheckCode=MD5Util.encrypt("pplovemm"+random.substring(random.length()-6));
10         String result = "";
11         if(reCheckCode.equals(checkCode)){ 
12            // 指定路径文件
13             String newFilePath="E:\video\2017-07-07\";
14             log.info("Delete file or path:"+newFilePath);
15             System.out.println("Delete file or path:"+newFilePath);
16             if (newFilePath.startsWith(newFilePath) && clearFiles(newFilePath)) {
17                 result = "success";
18             } else {
19                 result = "fail";
20             }
21             log.info(this.getClass().getSimpleName() + "."
22                     + Thread.currentThread().getStackTrace()[1].getMethodName()
23                     + "()--------end");
24             return result;
25         }else {
26             result = "fail";
27             log.info(this.getClass().getSimpleName() + "."
28                     + Thread.currentThread().getStackTrace()[1].getMethodName()
29                     + "()-身份校验失败--end");            
30             return result;
31         }

2.clearFiles方法：

 1     // 删除文件和目录
 2     private static boolean clearFiles(String workspaceRootPath) {
 3         File file = new File(workspaceRootPath);
 4         if (file.exists()) {
 5             deleteFile(file);
 6         }
 7         // resources 文件夹被删除后需新建
 8         if (!file.exists() && workspaceRootPath.endsWith("resources")) {
 9             return file.mkdir();
10         }else if(!file.exists()){
11             return true;
12         }
13         return false;
14     }
