Welogic的Log4j日志设置

基本上使用log4j的包放入到WEB-INF/lib/下

log4j.properties放到WEB-INF/classes下

即可。有文档说有其他设置，没必要了。

 

test.jsp

<textarea cols="50" rows="15" name="code" class="c-sharp">&lt;%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"&gt; &lt;%@ page import= "org.apache.log4j.Logger "%&gt; &lt;html&gt; &lt;head&gt; &lt;title&gt; Test Log4j &lt;/title&gt; &lt;/head&gt; &lt;body align=center&gt; &lt;% Logger log = Logger.getLogger( "Test Message: "); log.info( "Message from Log4j "); %&gt; log test &lt;/body&gt; &lt;/html&gt; </textarea>

 

log4j.properties

<textarea cols="50" rows="15" name="code" class="c-sharp">log4j.rootLogger = INFO,console,D,E # console output log4j.appender.console = org.apache.log4j.ConsoleAppender log4j.appender.console.layout = org.apache.log4j.PatternLayout log4j.appender.console.Target = System.out log4j.appender.console.layout.ConversionPattern=[%d{yyyy MMM dd HH:mm:ss,SSS}] [%5p ] %c{1}:%L -- %m%n # debug information output log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.File = testLog.log log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = %n[LOG Log] %d ==&gt; %m &lt;== %c{1}:%L # error information output log4j.appender.E = org.apache.log4j.DailyRollingFileAppender log4j.appender.E.encoding=UTF-8 log4j.appender.E.File = testError.log log4j.appender.E.Append = true log4j.appender.E.Threshold = ERROR log4j.appender.E.layout = org.apache.log4j.PatternLayout log4j.appender.E.layout.ConversionPattern = [%d{yyyy MMM dd HH:mm:ss,SSS}] [%5p ] %c{1}:%L -- %m%n</textarea>

 

java文件中

<textarea cols="50" rows="15" name="code" class="c-sharp"> private static Logger log = Logger.getLogger("test"); log.info( "action "); </textarea>

在domain下查看日志文件如下：

 

C:/bea/user_projects/domains/mydomain

结果：testLog.log
