spring mvc log4j 配置
1、首页在WEB-INF目录下新建 log4j.properties 配置文件,内容如下:
log4j.rootCategory = INFO,dailyFile log4j.appender.dailyFile=org.apache.log4j.DailyRollingFileAppender log4j.appender.dailyFile.Threshold=DEBUG log4j.appender.dailyFile.ImmediateFlush=true log4j.appender.dailyFile.Append=true log4j.appender.dailyFile.File=c:/logs/log.log log4j.appender.dailyFile.DatePattern=yyyy-MM-dd'.log' log4j.appender.dailyFile.layout=org.apache.log4j.PatternLayout log4j.appender.dailyFile.layout.ConversionPattern=[%-5p] %d(%r) --> [%t] %l: %m %x %n
2、修改web.xml配置,将如下配置加入到一级节点下:
<context-param> <param-name>log4jConfigLocation</param-name> <param-value>/WEB-INF/log4j.properties</param-value> </context-param> <listener> <listener-class> org.springframework.web.util.Log4jConfigListener </listener-class> </listener>
3、java文件中使用:
Logger log = Logger.getLogger(this.getClass().getName()); log.info(" logger"); log.error("error"); //log.debug("debug");
这里debug不会写入到日志中。详见log4j.properties 详细配置说明。
