How to make my URL mapping case insensitive?

Question

Grails, by default, is case-sensitive when mapping URL to controller actions or views.

For instance, www.mywebsite.com/book/list will work BUT www.mywebsite.com/Boo

Answer 1

Here is how I works on Grails 2.4 based on http://www.clearlyinnovative.com/case-insensitive-url-mappings-in-grails

      "/$_ctrl/$_action/$id?" {
        controller = { 
            def foundControllerMatch = false
            def returnCtrl = params._ctrl

            def grailsApplication = Holders.getGrailsApplication()


            grailsApplication.controllerClasses.each { GrailsClass c ->;
                def l_className = c.name.toLowerCase()

                // find the class
                if (params._ctrl?.equalsIgnoreCase(l_className) && foundControllerMatch == false) {
                    foundControllerMatch = true
                    returnCtrl = c.getLogicalPropertyName()
//                    println " foundControllerMatch ${returnCtrl}"
                }
            } 
            return returnCtrl
        }

        action = { 
            def foundActionMatch = false
            def returnAction = params?._action
            def returnCtrl = params._ctrl

            def grailsApplication = Holders.getGrailsApplication()

            grailsApplication.controllerClasses.each { GrailsClass c ->;
                def l_className = c.name.toLowerCase()

                // find the class
                if (params._ctrl?.equalsIgnoreCase(l_className) && foundActionMatch == false) {

                    returnCtrl = c.name

                    c.URIs.each { _uri ->;

                        if (foundActionMatch == false) {
                            def uri = _uri

//                            println "u-> $uri"

                            def uri_action
                            uri_action = uri.split('/')[2]

//                            println "uri_action-> $uri_action"
                            if (uri_action?.trim()?.equalsIgnoreCase(params._action.trim())) {
                                foundActionMatch = true
                                returnAction = uri_action
                            }
                        }
                    }
                }
            } 
            return returnAction 
        }

      }
