grails run-war 错误

Question

我有 grails 应用程序，并且在执行 run-app 时 - 一切正常！但是之后： grails run-war ，我收到以下错误：

 
Exception sending context initialized event to listener instance of class org.codehaus.groovy.grails.web.context.GrailsContextLoaderListener

感谢任何帮助。谢谢！

Answer 1

在 tomcat 上部署时，“ldap-server”插件也有同样的问题。
对我来说，修复方法是通过 ApplicationHolder 提供 servletContext

：

ServletContextHolder.servletContext

使用：

ApplicationHolder.application.parentContext.servletContext

TransientGrailsLdapServer.getWorkDir() 的完整源代码：

import org.codehaus.groovy.grails.commons.ApplicationHolder

private getWorkDir() {      
    def base = ApplicationHolder.application.parentContext.servletContext ? WebUtils.getTempDir(ApplicationHolder.application.parentContext.servletContext) : new File(BuildSettingsHolder.settings?.projectWorkDir, beanName)
    new File(base, "ldap-servers/$beanName")
}

Answer 2

行中的基本参数为 null 引起的

new File(base, "ldap-servers/$beanName")

该问题是由grails.ldap.server.TransientGrailsLdapServer.getWorkDir() 中的

，这表明配置问题，也许存在一些问题您的环境之间的差异导致基本参数为空？
