我遇到了一个我正在处理的grails应用程序的问题,我无法弄明白。 这是一个grails 2.0应用程序,应该在带有Tomcat7的Debian稳定版上运行。所以我构建了war文件并将其部署到Tomcat。一旦启动它,我就会在Tomcat日志文件(catalina.out)中获得以下日志输出:
SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".
SLF4J: Defaulting to no-operation (NOP) logger implementation
SLF4J: See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
28-Jan-2012 13:02:00 org.apache.catalina.core.StandardContext start
SEVERE: Error listenerStart
28-Jan-2012 13:02:00 org.apache.catalina.core.StandardContext start
SEVERE: Context [/Gibbons5] startup failed due to previous errors
28-Jan-2012 13:02:00 org.apache.catalina.loader.WebappClassLoader clearReferencesJdbc
SEVERE: The web application [/Gibbons5] registered the JBDC driver [com.mysql.jdbc.Driver] but failed to unregister it when the web application was stopped. To prevent a memory leak, the JDBC Driver has been forcibly unregistered.
我尝试通过将Tomcats loglevel增加到FINEST来使输出更加冗长,但这并没有给我任何更多信息。我还将应用程序的loglevel更改为debug,但这也无济于事。
在我的本地Tomcat上,一切运行良好,同样的战争和Tomcat7。

我遇到了同样的错误,但我发现了以下文章:
在简历中,您需要在WEB-INF / classes中创建logging.properties文件(您可以将其添加到webapps中的爆炸文件夹并重新启动tomcat)
logging.properties的内容可以是:
org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler
重启Tomcat后,您可以看到更详细的错误。

我在Tomcat7中遇到了同样的错误。我发现,如果我按照转换Tomcat使用log4j的说明,它可以捕获日志中的早期错误,但如果在Grails应用程序启动过程的早期发生错误,则使用默认的Tomcat配置,“Error listenerStart”全部你明白了。
