run-app 和 run-war 之间的 Grails 行为差异

我对 Groovy 和 Grails 还比较陌生，我正在业余时间尝试它们。我有一个小型测试 Grails 应用程序，可以使用 grails run-app 正常运行，但 grails run-war 会导致错误。

在 grails-app/conf/BootStrip.init 方法中，我将一些属性 getter 添加到 DefaultGrailsControllerClass 和 DefaultGrailsApplication 上：

DefaultGrailsControllerClass.metaClass.getMenuText = { ->
    getPropertyOrStaticPropertyOrFieldValue('menuText', String.class)
}
DefaultGrailsControllerClass.metaClass.getMenuOrder = { ->
    getPropertyOrStaticPropertyOrFieldValue('menuOrder', Integer.class)
}
DefaultGrailsApplication.metaClass.getMenuControllerClasses = { ->
    controllerClasses.findAll { it.menuText != null }.sort { it.menuOrder }
}

在我的 < code>grails-app/views/layouts/main.gsp，我正在使用这个：

<g:each var="c" in="${ grailsApplication.menuControllerClasses }">
    <li><g:link controller="${c.logicalPropertyName}">${c.menuText}</g:link></li>
</g:each>

这在 run-app 下工作正常，但在 run-war< 下运行它/code>，我得到以下信息：

groovy.lang.MissingPropertyException: No such property: menuControllerClasses for class: org.codehaus.groovy.grails.commons.DefaultGrailsApplication

我在 Grails 1.1.1 和 1.2-M1 下尝试过此操作并得到相同的结果。我已经验证了 BootStrap.init 方法正在被调用（通过 println），但是对 metaClass 所做的更改没有被调用似乎是在 run-war 下进行的。

知道我缺少什么吗？

I'm relatively new to Groovy and Grails and am trying them out in my spare time. I've got a small test Grails application that I'm able to run fine using grails run-app, but grails run-war results in an error.

In the grails-app/conf/BootStrip.init method, I'm adding some property getters onto the DefaultGrailsControllerClass and DefaultGrailsApplication:

DefaultGrailsControllerClass.metaClass.getMenuText = { ->
    getPropertyOrStaticPropertyOrFieldValue('menuText', String.class)
}
DefaultGrailsControllerClass.metaClass.getMenuOrder = { ->
    getPropertyOrStaticPropertyOrFieldValue('menuOrder', Integer.class)
}
DefaultGrailsApplication.metaClass.getMenuControllerClasses = { ->
    controllerClasses.findAll { it.menuText != null }.sort { it.menuOrder }
}

In my grails-app/views/layouts/main.gsp, I'm using this:

<g:each var="c" in="${ grailsApplication.menuControllerClasses }">
    <li><g:link controller="${c.logicalPropertyName}">${c.menuText}</g:link></li>
</g:each>

This works fine under run-app, but running it under run-war, I get the following:

groovy.lang.MissingPropertyException: No such property: menuControllerClasses for class: org.codehaus.groovy.grails.commons.DefaultGrailsApplication

I've tried this under Grails 1.1.1 and 1.2-M1 and get the same result. I've verified that the BootStrap.init method is being called (via a println), but the changes made to the metaClass don't appear to take under run-war.

Any idea what I'm missing?
