Tomcat之默认日志

我使用的是Tomcat7，默认情况是：

bin文件夹中已经有tomcat-juli.jar，

conf文件夹中已有logging.properties，默认设置是：

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler


org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].level = INFO

# For example, set the org.apache.catalina.util.LifecycleBase logger to log
# each component that extends LifecycleBase changing state:
#org.apache.catalina.util.LifecycleBase.level = FINE


# To see debug messages in TldLocationsCache, uncomment the following line:
#org.apache.jasper.compiler.TldLocationsCache.level = FINE

在logs文件夹中生成的文件有：catalina.2014-07-29.log、host-manager.2014-07-29.log、localhost.2014-07-29.log、manager.2014-07-29.log 4个文件，主要记录系统启动和关闭日志，以及一些管理日志和异常信息。

同时由于在conf文件夹下的server.xml中有以下配置：

<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log." suffix=".txt"
               pattern="%h %l %u %t &quot;%r&quot; %s %b" />

所以在logs文件夹中还会生成localhost_access_log.2014-07-29.txt文件（访问日志）。
