Tomcat7日志logging – 为什么两种不同的格式出来？

在Eclipse中我的logging.properties看起来像这样，当我最初发布这个问题：

 handlers = java.util.logging.ConsoleHandler org.apache.catalina.core=OFF java.util.logging.ConsoleHandler.level = FINE java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter java.util.logging.SimpleFormatter.format=JUL %4$s: %2$s%n%4$s: %5$s%n

在这个configuration下，我也在Linux服务器上遇到同样的问题：

 handlers = 2localhost.org.apache.juli.FileHandler, org.apache.juli.FileHandler .handlers = org.apache.juli.FileHandler 2localhost.org.apache.juli.FileHandler.level = INFO 2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs 2localhost.org.apache.juli.FileHandler.prefix = localhost. org.apache.juli.FileHandler.level = ALL org.apache.juli.FileHandler.formatter = java.util.logging.SimpleFormatter org.apache.juli.FileHandler.directory = ${catalina.base}/logs java.util.logging.SimpleFormatter.format=tomcat: %4$s: %2$s%n%4$s: %5$s%n org.apache.catalina.handlers = org.apache.juli.FileHandler org.apache.catalina.startup.level = SEVERE org.apache.catalina.session.ManagerBase.level = SEVERE org.apache.catalina.core.AprLifecycleListener.level=SEVERE org.apache.catalina.connector.level = SEVERE org.apache.coyote.level=SEVERE org.apache.catalina.level=ALL org.apache.catalina.startup.HostConfig.level = SEVERE org.apache.catalina.loader.WebappClassLoader.level = SEVERE org.apache.catalina.session.ManagerBase.level = INFO # ServletContext logger org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = ALL org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler org.apache.catalina.core.ContainerBase.[Catalina].[localhost].formatter = java.util.logging.SimpleFormatter org.apache.catalina.core.ContainerBase.[Catalina].[localhost].format=servlet: %4$s: %2$s%n%4$s: %5$s%n

为什么然后我的控制台login到Eclipse看起来像这样？

裸INFO消息来自哪里？

为什么catalina.core信息仍然显示，即使我把它们设置为OFF？

在Linux服务器上，JULI日志如下所示：

 tomcat: FINE: org.apache.catalina.core.ContainerBase addChildInternal FINE: Add child StandardHost[localhost] StandardEngine[Catalina] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [StandardServer[8005]] to [INITIALIZING] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [org.apache.catalina.deploy.NamingResources@13fee20c] to [INITIALIZING] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [org.apache.catalina.deploy.NamingResources@13fee20c] to [INITIALIZED] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [StandardService[Catalina]] to [INITIALIZING] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [StandardEngine[Catalina]] to [INITIALIZING] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [StandardEngine[Catalina]] to [INITIALIZED] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [Connector[HTTP/1.1-8080]] to [INITIALIZING] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [org.apache.catalina.connector.MapperListener@737996a0] to [INITIALIZING] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [org.apache.catalina.connector.MapperListener@737996a0] to [INITIALIZED] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [Connector[HTTP/1.1-8080]] to [INITIALIZED] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [StandardService[Catalina]] to [INITIALIZED] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [StandardServer[8005]] to [INITIALIZED] tomcat: FINE: org.apache.catalina.util.LifecycleBase setStateInternal FINE: Setting state for [StandardServer[8005]] to [STARTING_PREP] tomcat: FINE: org.apache.catalina.core.NamingContextListener lifecycleEvent FINE: Bound StandardServer[8005] tomcat: FINE: org.apache.catalina.core.NamingContextListener createNamingContext FINE: Creating JNDI naming context tomcat: FINE: org.apache.catalina.core.NamingContextListener addResource

同样的问题适用，为什么不是所有的行都以tomcat:开头tomcat: ？

更新在debugging的时候，我发现每个日志条目的BOTH LINES来自java.util.logging.Logger.logp（）在这里输入图像描述

在Eclipse中我的logging.properties

我不知道你的工作区是如何配置的。也许这个文件根本不用。

Java记录由系统属性配置。

您需要一个属性（ -Djava.util.logging.manager ）将org.apache.juli.ClassLoaderLogManager配置为Java日志记录的日志管理器实现。

您需要其他属性（ -Djava.util.logging.config.file ）来配置配置文件的路径。

通常，这两个属性都是由启动脚本（ catalina.sh ， catalina.bat ）设置的，但是Eclipse不需要该脚本的帮助就可以直接启动java，因此必须在启动配置中明确设置这些系统属性。

Tomcat JULI支持每个类加载器的日志记录配置。

此功能允许通过使用它打包WEB-INF/classes/logging.properties文件来为每个Web应用程序单独配置日志记录。

如果意外地将logging.properties文件放入classpath中，它将会产生相同的效果：它将取代由该类加载器加载的类的默认配置。

例如，已知Jollyday库的一些版本（4年前）包含一个意外的logging.properties文件，该文件启用了FINE日志记录。

.level = ALL

答案一直在盯着我们，从发布的顶部：

 java.util.logging.SimpleFormatter.format=JUL %4$s: %2$s%n%4$s: %5$s%n ^^^^^^^

额外的%n%4$s:格式字符串是什么导致额外的行显示。咄。

您提到的信息消息实际上并不是核心的一部分。它们是由不同包中的类生成的。通过解剖catalina库并确定负责特定日志的类，这里是防止tomcat 7.0.63上的日志的配置，通过附加到默认logging.properties ：

 org.apache.catalina.startup.level=OFF org.apache.catalina.startup.handlers=1catalina.org.apache.juli.FileHandler.level org.apache.catalina.core.level=OFF org.apache.catalina.core.handlers=1catalina.org.apache.juli.FileHandler.level org.apache.coyote.level=OFF org.apache.coyote.handlers=1catalina.org.apache.juli.FileHandler.level

我认为你错过了JUL-to-slf4j。在这里看到更多的细节slf4j遗产桥文件

FINE，ALL，INFO，WARN，ERROR，SEVERE等都是每个记录器的日志级别。将它们全部切换到SEVERE以使最少的日志输出。 ALL，基本上就是一个详细标志的日志记录等价物。 FINE是第二高的日志输出速率。
