上传文件在服务器端保存位置问题
1.保存在可以被浏览器直接访问的位置
例如:商城的商品图片
保存在工程的WebRoot下的路径(不包含META-INF以及WEB-INF目录及其子目录)
2.保存在不能被浏览器直接访问的位置
例如:付费的视频。
1.工程中 META-INF WEB-INF目录及其子目录
2.不在工程中的服务器的磁盘目录下.- After uploading a file, save the location on the server side
The first storage location: WebRoot placed directly under the other directory and subdirectory of the WEB-INF other, for example, META-INF: WebRoot / upload
* The client can access the browser via url location (data without going through access control, and can directly access) require the user to upload directly ---- resource security less demanding, or resources directly visible
* For example: Shopping Mall Picture
The second category storage location: WEB-INF placed or not and its sub-directory management server tomcat example: WebRoot / WEB-INF / upload, c: \, d: \ abc
* Clients can not be directly accessed through the URL, the server must be able to read by the internal program (high security, you can easily add access control)
* For example: membership online video
