You need Javascript / JQuery for that. Below an example:

setTimeout( function(){ 
    $('div.alert').fadeOut("slow"); }, 
5000 );

More information with setTimeout here

You can also use delay() (more information here)

Example:

def myController() {
    def message
    if (fruit==apple){
       // Do something
    } else {
       message = 'Your message' 
    }
    return [message:message, ...]
}

In your view:

<g:if test="${ message }">
 ...
</g:if>

And don't forget to enable alert:

$(".alert").alert()

Hope this helps
