Issue wtih @RequestMapping

[toms]

My Handler method mapping is defined as below.

@RequestMapping(value = "{categoryPath}/category.action", method = RequestMethod.GET)
	public ModelAndView showCategory(@PathVariable("categoryPath") final String category, final HttpServletRequest request,
			final HttpServletResponse response) {
//Biz Logic
}

My issue is that, the request mapping does not match URIs of the form abcd/efgh/category.action. However, it matches abcd/category.action.

I tested out the mapping with UriTemplate class like below:

final UriTemplate template = new UriTemplate("{category}/category.action");

		System.out.println(template.match("abcd/efgh/category.action"));

The output generated is:

{category=abcd/efgh}

So then why does my request mapping not work with abcd/efgb/category.action ?

I use spring 3.

Okay, I figured out the reason.

DefaultAnnotationHandlerMapping which is registered by default in DispatcherServlet uses AntPathMatcher to do the pattern matching.

The logic adopted is roughly as below:

Split the pattern string and the path string using the path separator as the delimiter(the default path separator is '/' )

So taking the example in the previous post, the pattern will be split into [{categoryPath},category.action] and the path to [abcd,efgh,category.action]

The logic then attempts to match the elements of the pattern array and path array one-on-one.

ie, {categoryPath} against abcd [PASS]
category.action against efgh [FAIL]

So now I know the reason why url /abcd/efgh/category.action does not match with
{categorypath}/category.action but I do not know how to frame the pattern for this genuine scenario.

Ideas anyone?
