In Grails 3.3.0, I'm having an issue with getting it to use the UrlMappings that I've defined. For instance, I'm trying to have "/" map to the default controller/action.
This works locally (I've turned on logging for 'org.grails.plugins.web.mapping').
I see this in log:
2017-09-01 18:08:05,254 [http-nio-8080-exec-2] DEBUG org.grails.web.mapping.DefaultUrlMappingsHolder - Attempting to match URI [/] with pattern [500] 2017-09-01 18:08:05,254 [http-nio-8080-exec-2] DEBUG org.grails.web.mapping.DefaultUrlMappingsHolder - Attempting to match URI [/] with pattern [/] 2017-09-01 18:08:05,302 [http-nio-8080-exec-2] DEBUG org.grails.web.mapping.DefaultUrlMappingsHolder - Matched URI [/] with pattern [/], adding to posibilities
...and the default controller/action is what I see.
In the Tomcat container, I see this:
09-01 17:44:35,968 [ajp-bio-8009-exec-1] DEBUG org.grails.webflow.mvc.servlet.GrailsFlowHandlerMapping - Looking up Grails controller for URI [/] 2017-09-01 17:44:36,019 [ajp-bio-8009-exec-1] TRACE org.grails.web.servlet.mvc.GrailsDispatcherServlet - Testing handler map [org.grails.web.mapping.mvc.UrlMappingsHandlerMapping@17ef7838] in DispatcherServlet with name 'grailsDispatcherServlet'
but I don't see it attempt to match against "/". Or the 500, for that matter. Any ideas on what else to look for to troubleshoot this?
