MockMvc isn't matching handler mappings [SPR-12976]

I'm trying to run some MockMvc test with the new HtmlUnit support, but for some reason MockMvc isn't matching mappings:

Excerpts from Geb spec; can fill in if there's something particular that's needed:

    @Autowired
    StaticPagesHtmlController c

    MockMvc buildMvc() {
        MockMvcBuilders.standaloneSetup(c).build()
    }

    def setup() {
        MockMvc mvc = buildMvc()
        driver = new MockMvcHtmlUnitDriver(mvc, true)
        browser.driver = driver
    }

Please provide the source code for StaticPagesHtmlController so that we can analyze your mappings (i.e., your use of @RequestMapping, etc.).

This is puzzling indeed. The mapping in the log file seems to match the URL:

Mapped "{[/about/{page}/{page2}],methods=[],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto ...

Have you checked if the same works with just Spring MVC Test, i.e. not using the HtmlUnit extension? I don't see why it would matter but worth trying to isolate the problem.

Aside from that I would have expected a little more logging from the request processing. Is org.springframework.web on DEBUG? If not could you provide more logging output. Perhaps you can debug a little inside AbstractHandlerMethodMapping to understand what's going on. If not provide a sample and I'll take a look.

I suspect this is due to the fact that the HtmlUnit extension currently assumes the first path segment is the context root. This means that your GebConfig.groovy should include a URL that contains a context root other than "/" even if your application's context root is /.

For example, the following will not work because baseUrl does not contain a context root:

reportsDir = 'build/geb-reports/'
baseUrl = 'http://localhost:8080/'
driver = { new org.openqa.selenium.htmlunit.HtmlUnitDriver(true) }

The following will work because the context root is not "/"

reportsDir = 'build/geb-reports/'
baseUrl = 'http://localhost:8080/context/'
driver = { new org.openqa.selenium.htmlunit.HtmlUnitDriver(true) }

The good news is that I am currently working on putting together an RC which will allow configuring the context root used in the tests.

If you have any thoughts on the default I'd appreciate feedback on spring-projects/spring-test-htmlunit/issues/40.

Resolving in favor of the linked issue under HtmlUnit but feel free to re-open if needed.
