grails - Grails - 通过应用程序上下文获取 taglib bean

Question

当尝试通过以下方式将实例获取到控制器中的自定义标记库时：

def myTagLib = grailsApplication.mainContext.getBean('com.mypackage.MyTagLib')

我收到以下错误：

没有定义名为“com.mypackage.MyTagLib”的 bean。Stacktrace 如下： org.springframework.beans.factory.NoSuchBeanDefinitionException：没有定义名为 'com.mypackage.MyTagLib' 的 bean

但是，我能够毫无问题地获得内置 taglib 的实例：

def g = grailsApplication.mainContext.getBean('org.codehaus.groovy.grails.plugins.web.taglib.ValidationTagLib')

根据以下内容，这应该有效。有谁知道为什么我的 taglib 不会被识别为有效的 bean？

我正在使用 Grails 2.4.0

According to Section 8.3.5 of the Grails Documentation, if your taglib is namespaced (which is generally a good practice), you can simply call taglib methods by using your namespace as the prefix to the method call.

For instance, if you have a taglib namespaced "my" and it has a method called "smiley" that accepts an attribute "happy", you could have the following line in a controller with no extra imports necessary:

my.smiley(happy: true)
