Spring MVC @PathVariable with dot (.) is getting truncated.

问题：

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?

回答：

Try a regular expression for the @RequestMapping argument:

RequestMapping(method = RequestMethod.GET, value = Routes.BLAH_GET + "/{blahName:.+}")
