grails - 如何使用Grails WebXmlConfig插件将属性添加到WEB.XML文件？

Question

我正在使用Grails的WebXmlConfig Plugin。我使用插件的1.4.1版本。我做了:

grails create-web-xml-config

生成grails-app / conf / WebXmlConfig.groovy文件。当我尝试添加一个简单的属性，如:

sessionConfig.sessionTimeout = 30

我收到以下错误:

当我执行grails install-templates并从生成的web.xml文件中删除 session 超时后，它就可以工作了。如何在不修改原始web.xml的情况下配置WebXmlConfig.groovy？

为什么不使用grails安装模板并修改默认的web.xml文件作为解决方法？
