如何使服务器上的文件可用于客户端Web浏览器（使用Java编写的服务器）

Question

My Java application is using jetty running an embedded server, the idea being my software can then be controlled by a browser from a phone/ipad with the server running on PC/Mac ecetera.

I want the user to be able to browse folders on the server from webpage within their browser, not on their client so I was thinking that webdav might be the answer, but how do I even get started with this. All I want them to be able to do is view a browser tree of folders on the server and pick a folder, this folder is then stored in a Form text field and submitted to the server. That is all I need it to do.

So currently you can use file input type to allow users to browse for files on their computer, but I need the same functionality but for browsing files on the server.

<input type="file" name="img">

I realize this is not out of the box behaviour but I have seen it implemented before so how is it done ?

It seems the server would have to provide the file structure, I could try and create this in my backend but hopefully there is something that already done this. Then it has to be rendered on the front-end I assume there is already something for rendering a file structure ?

I found this question Server Side File Browsing which asks essentially the same question, however it is very old and I believe outdated.

Answer 1

The solution I am implementing is to use jsTree on the client in ajax mode to contact the server as the user clicks on nodes so it only gets the data as required. The server code makes use of java FileVisitor class to construct the required part of the folder tree and return it jsTree in json format.
