Grails URL映射导致GSP出错

本文介绍了Grails URL映射导致GSP出错的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个网址与此类似：

  p> 
 
 
 名称前缀：/ $ prefix / $ controller / $ action？/ $ id？{
 constraints {} 
 
  
 GSP： 
 
 
 < g：link mapping =prefixparams =[前缀：$前缀，控制器：...]> abc< / g：link> 
  
要使用 sortableColumn ，只需将所有 params 属性中的URLMapping参数：
 < g：sortableColumn property =coltitle =titleparams =[prefix：'prefix'，controller：'controller'，action：'action']/> 
  
 
I have a site that have URL similar to this:
/mysite/admin/controller/action/id
/mysite/search/controller/action/id
/mysite/user/controller/action/id
I have my URL mapping like this
"/$prefix/$controller/$action?/$id?"{
    constraints {}
}
I am able to get to the controller correctly.
But on the GSP side
<g:link controller="controller">abc</g:link> ==> <a href="/mysite/controller/...">abc</a>
Notice how I lose the prefix between mysite and the controller.
 解决方案 
You can use named url mappings and then pass the prefix as part of the params:
URLMappings:
name prefix: "/$prefix/$controller/$action?/$id?"{
    constraints {}
}
GSP:
<g:link mapping="prefix" params="[prefix:$prefix, controller:...]">abc</g:link>
To use sortableColumn, just put all of the URLMapping parameters in the params property:
<g:sortableColumn property="col" title="title" params="[ prefix: 'prefix', controller:'controller', action:'action']" />
