Question

我有grails应用程序，在运行应用程序时 - 一切正常！但是之后：grails run-war，我得到了一个错误：

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

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'd1LdapServer': Invocation of init method failed; nested exception is groovy.lang.GroovyRuntimeException: Ambiguous method overloading for method java.io.File#.

感谢任何帮助。谢谢！

Answer 1

在tomcat上部署时，“ldap-server”插件存在同样的问题。对我来说，修复是通过ApplicationHolder提供servletContext

代替：

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

问题是由行

中的基本参数为空引起的

新文件（base，“ldap-servers / $ beanName”）

in grails.ldap.server.TransientGrailsLdapServer.getWorkDir（）

这指出了一个配置问题，也许你的环境之间存在一些差异导致base参数为null？

与grails run-war的错误
