Grails grailApplication.controllerClasses按包排序控制器

问题描述

我有以下代码抓取所有控制器，排序和输出在li标签：

 < g： each var =cin =$ {grailsApplication.controllerClasses.sort {it.fullName}}> 
< li<％= c.logicalPropertyName == controllerName？ 'class =active'：''％>> 
< g：link controller =$ {c.logicalPropertyName}> $ {c.naturalName}< / g：link> 
< / li> 
< / g：each> 
  

我需要通过软件包过滤出控制器，例如grab控制器。 >

例如：

  com.app.module.mars.controller.HelloController 
 com.app.module.venus.controller.PrintController 
  

m包装控制器由模块，所以火星将有自己的一套控制器和金星将有自己的。然后在UI中我想使用上面的代码（有一些过滤器），它将显示模块作为主菜单和他们的控制器作为下拉菜单。

如何应用过滤器？或者如果你能指导我在正确的方向是伟大的。感谢。

解决方案

您可以使用，它接受一个类和一个包列表作为参数。所以这应该做的诀窍：

  GrailsClassUtils.isClassBelowPackage（c.class，['com.app.module.mars'] ）
  

编辑： grailsApplication.controllerClasses 您列出了 GrailsClass 对象，因此您需要使用 c.clazz 而不是 c.class like

  grailsApplication.controllerClasses.each {c  - > 
 GrailsClassUtils.isClassBelowPackage（c.clazz，['com.app.module.mars']）
} 
  

I have the following code that grabs all controllers, sorts it, and outputs in li tags:

<g:each var="c" in="${grailsApplication.controllerClasses.sort { it.fullName } }">
        <li<%= c.logicalPropertyName == controllerName ? ' class="active"' : '' %>>
                <g:link controller="${c.logicalPropertyName}">${c.naturalName}</g:link>
        </li>
</g:each>

I have a need to filter out controllers by package i.e. grab controller from a certain package.

For example:

com.app.module.mars.controller.HelloController
com.app.module.venus.controller.PrintController

As you can see I'm packaging controllers by modules, so mars will have its own set of controllers and venus will have its own. Then in the UI I want to use the above code (with some filter) which will show modules as main-menus and their controllers as dropdowns.

How can I apply such a filter? Or if you could guide me in the right direction would be great. Thanks.

解决方案

You can use GrailsClassUtils.isClassBelowPackage() which takes a class and a list of packages as the arguments. So this should do the trick:

GrailsClassUtils.isClassBelowPackage(c.class, ['com.app.module.mars'])

Edit: grailsApplication.controllerClasses probably gives you a list of GrailsClass objects, so you'd want to use c.clazz instead of c.class like

grailsApplication.controllerClasses.each { c ->
    GrailsClassUtils.isClassBelowPackage(c.clazz, ['com.app.module.mars'])
}
