Java servlet cuts off file extension -

i'm attempting serve local or proxy files via java application.

with this

    @responsebody @requestmapping(value = "/file/{file}", method = requestmethod.get) public void doget(httpservletrequest request, httpservletresponse response,@pathvariable("file") string f) throws ioexception {      string filename = urldecoder.decode(f, "utf-8");     file file = new file("resources/files/", filename);     response.setheader("content-type", "video/mp4");     response.setheader("content-length", string.valueof(file.length()));     response.setheader("content-disposition", "inline; filename=\"" + file.getname() + "\"");     files.copy(file.topath(), response.getoutputstream());  } 

with example url such

example.com/file/out2kp2_1.mp4

i'm getting error:

problem accessing /file/out2kp2_1.mp4. reason:

resources\files\out2kp2_1 caused by:

java.nio.file.nosuchfileexception: resources\files\out2kp2_1 @ sun.nio.fs.windowsexception.translatetoioexception(windowsexception.java:79)

if add trailing / url , requestmapping, works, on ios , few other places video player doesn't seem loading file trailing slash doesn't suit purposes.

any appriciated.

thanks mark down. take didn't know answer!?

it's problem spring, have add :.+ file url variable

i.e. @requestmapping(value = "/file/{file:.+}", method = requestmethod.get)
