cache_sweeper方法未找到

我正在將我的Rails 3應用程序部署到Tomcat 6服務器。我一直在使用warble將我的項目打包成war文件，到目前爲止還沒有任何麻煩。我剛剛在我的應用程序中添加了一個cache_sweeper。當我嘗試點擊應用程序時，我收到了標準的500錯誤頁面。cache_sweeper方法未找到

看我的日誌，我看到了這一點：

org.jruby.rack.RackInitializationException: undefined method `cache_sweeper' for ApplicationController:Class

它找不到cache_sweeper方法？這不是Rails的一部分嗎？

這在開發模式下不會發生，儘管在開發中我使用MRI ruby並使用rails服務器代替。

任何人有任何想法？

不管什麼原因，你必須使用JRuby /顫聲時包括該模塊。但是，使用MRI和導軌服務器時，此步驟不是必需的。

我說這個我ApplicationController和它的工作：

class ApplicationController < ActionController::Base 
    include ActionController::Caching::Sweeping if defined?(JRUBY_VERSION) 
    ... 
end
