Grails 3 Url Mappings

Question

如何创建默认值，匹配所有模式？

对于Ex：

"/"(controller: "home", action: "index")
"401"(controller: "error", action: "unauthorized")
"404"(controller: "error", action: "nF")
"500"(controller: "error", action: "err")

当用户点击应用程序http://myapp.com/appName/时，会调用/ mapping。我们如何添加模式以便甚至调用url http://myapp.com/appName（没有fordward斜杠）？

到目前为止，我已尝试执行以下操作：

""(controller: "home", action: "index")
" "(controller: "home", action: "index")
"*"(controller: "home", action: "index")
"*/**"(controller: "home", action: "index")
any(controller: "home", action: "index")

但是所有错误都会产生，其中一些包括：

MissingMethodException: No signature of method: org.grails.web.mapping.DefaultUrlMappingEvaluator$UrlMappingBuilder.any() is applicable for argument types:
No signature of method: org.grails.web.mapping.DefaultUrlMappingEvaluator$UrlMappingBuilder.*/**() is applicable for argument types:

模式应始终以正斜杠开头：

 "/**"(controller: "home", action: "index")
