link directly to GSP | 易学教程

问题

In a GSP, is it possible to create a direct link to another GSP? I know I can use:

<g:createLink controller="user" action="foo"/>

and in UserController define the foo action to just show the corresponding GSP

class UserController {
    def foo = {}
}

But is there any way I can achieve the same result without having to create the empty foo action?

Thanks, Don

The createLink tag is geared for use with controller actions and won't do what you want it to outside of the url attribute.

You can always get to a gsp by directly: /user/foo.gsp with a combination of the link and resource tags.

<g:link url="${resource(dir:'user', file:'foo.gsp')}">user/foo.gsp</g:link>

Othewise you can create a URL Mapping that maps a request directly to a view.

class UrlMappings {
    static mappings = {
        "/user/foo"(view:"user/foo")
    }
}

Using Grails 1.2 you can create a named URL Mapping that maps directly to a view:

class UrlMappings {
    static mappings = {
        name userFoo: "/user/foo"(view:"user/foo")
    }
}

and then use it with the link tag:

<link:userFoo>User Foo</link:userFoo>

<g:link mapping="userFoo">User Foo</g:link>

There's a uri attribute that's undocumented , but you can see it in the source:

<a href="${createLink(uri:'/path/page.gsp')}">link</a>

As of Grails 2.x, this is not possible. The ability to link directly to a .gsp was a security flaw that could be used to avoid the @Secured annotation. The URL mapping method does still work though as seen in @Colin Harrington's answer.
