SSI框架中配置log4j

事实上主要是log4j配置，跟SSI关系不大。

web.xml中加入

<context-param>
      <param-name>log4jConfigLocation</param-name>
      <param-value>/WEB-INF/localconf/log4j.properties</param-value>
   </context-param>
   <context-param>
      <param-name>log4jRefreshInterval</param-name>
      <param-value>6000</param-value>
   </context-param>
   
    <listener>
      <listener-class>
        org.springframework.web.util.Log4jConfigListener
      </listener-class>

#log4j.rootLogger = [ level ] , appenderName, appenderName, ...
log4j.rootLogger = DEBUG, console, R
#level=INFO,all can be output
#console is set to be a ConsoleAppender
log4j.appender.console = org.apache.log4j.ConsoleAppender
#console have four patterns
#org.apache.log4j.HTMLLayout
#org.apache.log4j.PatternLayout
#org.apache.log4j.SimpleLayout
#org.apache.log4j.TTCCLayout
log4j.appender.console.layout = org.apache.log4j.PatternLayout
#define the output type
log4j.appender.console.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] %m%n
#file is set to output to a extra file
log4j.appender.R = org.apache.log4j.RollingFileAppender
#the absolute route of the log4j file
log4j.appender.R.File = /log.txt
#the size
log4j.appender.R.MaxFileSize = 500KB
#back up a file
log4j.appender.R.MaxBackupIndex = 1
log4j.appender.R.layout = org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern=%-d{yyyy-MM-dd HH:mm:ss} [%c]-[%p] - %m%n
