tomcat - 应用布局 : main 时出错

Question

我是 grails 的新手，正在尝试将 helloworld grails 应用程序部署到 tomcat。

我创建了war文件，然后将war文件放在tomcat的webapps目录下。然后我从 bin 文件夹启动 tomcat 并跟踪日志。应用程序已部署，日志中没有任何错误。

现在当我尝试从浏览器访问应用程序时出现此错误

Error 500 - Internal Server Error.

Error applying layout : main

注意:当我执行 grails run-app 时，应用程序运行完美。

谁能帮我弄清楚这与什么有关以及我该如何解决。

问题与堆栈跟踪行有关:没有方法签名:gsp_helloworld_layoutsmain_gsp.assetPath() 适用于参数类型:(java.util.LinkedHashMap) 值:[[src:favicon.ico]]。

因此，在引用 favicon.ico 期间，您在 views/layouts/main.gsp 中为布局 View 提供了错误类型的参数。
