Question

我将一个grails 2应用程序部署到tomcat7中，它不会启动。我尝试了很多东西来从catalina.out或我的应用程序日志中获取任何信息，但我得到的只是

Jul 30, 2012 5:47:40 PM org.apache.catalina.core.StandardEngine startInternal
INFO: Starting Servlet Engine: Apache Tomcat/7.0.28

Jul 30, 2012 5:47:49 PM org.apache.catalina.startup.Catalina start
INFO: Server startup in 8372 ms

我已经将logging.properties放入包含

的/ var / lib / tomcat / webapps / myApp / WEB-INF / classes

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

但这也没有给我任何更多信息。

另外，我将grails app的loglevel更改为debug，但也没有出现错误。目前我不知道如何从tomcat或应用程序中获取任何有用的信息，帮助我找到错误：（

干杯，

更新

对于我正在尝试运行的环境，我的Config.groovy看起来像这样：

staging {
    def logDirectory = "/var/log/myApp"

    log4j = {
        appenders {
            rollingFile name: 'stacktrace', file: "${logDirectory}/stacktrace.log".toString(), maxFileSize: '10MB'
            rollingFile name: 'myLog', file: "${logDirectory}/myApp_debug.log".toString(), maxFileSize: '10MB'
        }

        root {
            // change the root logger to myLog file
            debug 'myLog'
        }

        debug  'grails.app'
        debug  'org.codehaus.groovy.grails.commons' // Core artifact information such as class loading etc.
        debug  'org.codehaus.groovy.grails.web' //Grails web request processing
        debug  'org.codehaus.groovy.grails.web.mapping' // URL mapping debugging
        debug  'org.codehaus.groovy.grails.plugins' //  Log plugin activity
        warn  'grails.spring' // See what Spring beans Grails and plugins are defining
        debug  'org.springframework' // See what Spring is doing
        debug  'org.hibernate' // See what Hibernate is doing
        debug  'org.codehaus.groovy.grails.web.servlet'  //  controllers
        debug  'org.codehaus.groovy.grails.web.pages' //  GSP
        info  'org.apache.catalina' // tomcat

        // set level for my messages; this uses the root logger (and thus the tomcatLog file)
        debug 'myApp_debug.log'
    }

    grails.serverURL = "someUrl"
}

Answer 1

查看所有日志文件 - catalina.out很少有真正的问题。 logs / localhost.2012-07-30.log和stacktrace.log是你最好的选择。

Answer 2

好吧所以我终于找到了这个bug。我找不到任何方法在日志中获得警告或错误。无论如何，我的错误在我的应用程序的可搜索配置中撒谎。

grails app无法在Tomcat7中启动 - 无法从日志中获取任何有用信息？
