How can I get real path for file in my WebContent folder?

Question

I need to get real path for file in my WebContent directory, so that framework that I use can access that file. It only takes String file as attribute, so I need to get the real path to this file in WebContent directory.

I use Spring Framework, so solution should be possible to make in Spring.

Answer 1

In situations like these I tend to extract the content I need as a resource (MyClass.getClass().getResourceAsStream()), write it as a file to a temporary location and use this file for the other call.

This way I don't have to bother with content that is only contained in jars or is located somewhere depending on the web container I'm currently using.

Answer 2

If you need this in a servlet then use getServletContext().getRealPath("/filepathInContext")!

Answer 3

Include the request as a parameter. Spring will then pass the request object when it calls the mapped method

@RequestMapping .....
public String myMethod(HttpServletRequest request) {
   String realPath = request.getRealPath("/somefile.txt");
   ...

Answer 4

You could use the Spring Resource interface (and especially the ServletContextResource): http://static.springsource.org/spring/docs/current/javadoc-api/org/springframework/core/io/Resource.html
