Spring MVC @PathVariable getting truncated

I have a controller that provides RESTful access to information:

@RequestMapping(method = RequestMethod.GET, value = Routes.BLAH_GET + "/{blahName}")
public ModelAndView getBlah(@PathVariable String blahName, HttpServletRequest request,
                            HttpServletResponse response) {

The problem I am experiencing is that if I hit the server with a path variable with special characters it gets truncated. For example: http://localhost:8080/blah-server/blah/get/blah2010.08.19-02:25:47

The parameter blahName will be blah2010.08

However, the call to request.getRequestURI() contains all the information passed in.

Any idea how to prevent Spring from truncating the @PathVariable?

This is probably closely related to SPR-6164. Briefly, the framework tries to apply some smarts to the URI interpretation, removing what it thinks are file extensions. This would have the effect of turning blah2010.08.19-02:25:47 into blah2010.08, since it thinks the .19-02:25:47 is a file extension.

As described in the linked issue, you can disable this behaviour by declaring your own DefaultAnnotationHandlerMapping bean in the app context, and setting its useDefaultSuffixPattern property to false. This will override the default behaviour, and stop it molesting your data.

I also ran into the same issue, and setting the property to false didn't help me either. However, the API says:

Note that paths which include a ".xxx" suffix or end with "/" already will not be transformed using the default suffix pattern in any case.

I tried adding "/end" to my RESTful URL, and the problem went away. I'm not please with the solution, but it did work.

BTW, I don't know what the Spring designers were thinking when they added this "feature" and then turned it on by default. IMHO, it should be removed.
