第一步：引入相应的jar包（我用的Spring版本为：spring-framework-2.0-with-dependencies）
*Spring_home/dist/spring.jar
*spring_home/lib/log4j/log4j-1.2.14.jar
*spring_home/lib/jakarta-commons/commons-logging.jar
第二步：配置Spring配置文件applicationContext.xml
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-2.0.xsd"> </beans>第三步：提供log4j.properties配置文件
# For JBoss: Avoid to setup Log4J outside $JBOSS_HOME/server/default/deploy/log4j.xml! # For all other servers: Comment out the Log4J listener in web.xml to activate Log4J. log4j.rootLogger=INFO, stdout, logfile log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d %p [%c] - %m%n log4j.appender.logfile=org.apache.log4j.RollingFileAppender log4j.appender.logfile.File=${petstore.root}/WEB-INF/petstore.log log4j.appender.logfile.MaxFileSize=512KB # Keep three backup files. log4j.appender.logfile.MaxBackupIndex=3 # Pattern to output: date priority [category] - message log4j.appender.logfile.layout=org.apache.log4j.PatternLayout log4j.appender.logfile.layout.ConversionPattern=%d %p [%c] - %m%n效果图如下：
好了好了好了，知道你累了，去玩儿吧！
