如何将 grails 3 中的动作映射到“/”?

How to map an action in grails 3 to "/"?

我正在使用 Grails 3.3.10 并尝试将“/”映射到控制器操作,用户在成功登录后被重定向。

在 UrlMappings 中我有:

class UrlMappings {

   static mappings = {

      "/"(controller:'app')
   ...
...

当用户登录时,应用程序被重定向到根 http://localhost:8090/,但它显示了从 Grails 生成的视图:

Welcome to Grails

Congratulations, you have successfully started your first Grails
application! At the moment this is the default page, feel free to
modify it to either redirect to a controller or display whatever
content you may choose. Below is a list of controllers that are
currently deployed in this application, click on each to execute
its default action:

Available Controllers:

....

我删除了默认 index.gsp 和 main.gsp 布局,但带有控制器的视图仍然出现,我无法执行我的操作。

如果我删除 UrlMapping“/”(控制器:'app'),操作执行正常并且视图是正确的,但是 URL 是 http://localhost:8090/app/index

是否可以显示来自 app/index 的视图作为 URL 映射到“/”?

Is it possible to display the view from app/index being the URL mapped to "/"?

是的。在 https://github.com/jeffbrown/pablopazosurlmapping.
