Question

我是新來的grails，並且正在嘗試將一個helloworld grails應用程序部署到tomcat。

我創建了war文件，然後將war文件放在tomcat的webapps目錄下。然後，我從bin文件夾啓動了tomcat並跟蹤了日誌。該應用程序在日誌中沒有任何錯誤地部署。

現在，當我嘗試從瀏覽器中我得到這個錯誤

Error 500 - Internal Server Error. 

Error applying layout : main 

注意訪問應用程序：當我做一個Grails運行的應用程序，該應用程序完美運行。

有人可以幫我解決這個問題，以及我如何解決這個問題。

問題是與堆棧跟蹤線路連接：No signature of method: gsp_helloworld_layoutsmain_gsp.assetPath() is applicable for argument types: (java.util.LinkedHashMap) values: [[src:favicon.ico]]。

因此，在參考favicon.ico期間，您在版面視圖views/layouts/main.gsp中提供了錯誤類型的參數。
