在web.xml上配置如下：
<!-- 配置log4j begin --> <context-param> <param-name>webAppRootKey</param-name> <param-value>bjgjqrcode.root</param-value> <!-- .root --> </context-param> <context-param> <param-name>log4jConfigLocation</param-name> <param-value>WEB-INF/log4j.properties</param-value> <!-- 配置文件存放路径 --> </context-param> <listener> <listener-class> org.springframework.web.util.Log4jConfigListener </listener-class> </listener> <!-- 配置log4j end --> |
3. log4j.properties 文件配置如下：
log4j.rootLogger = DEBUG,console,E,I,D#log4j.appender.file.DatePattern = yyyy-MM-dd'.log'#debug message do not output to the file. #output message in consolelog4j.appender.console = org.apache.log4j.ConsoleAppender log4j.appender.console.layout = org.apache.log4j.PatternLayout log4j.appender.console.layout.ConversionPattern = [%-5p][%-22d{yyyy/MM/dd HH\:mm\:ssS}][%l]%n%m%n log4j.appender.console.Threshold = DEBUG log4j.appender.console.ImmediateFlush = TRUE log4j.appender.console.Target = System.out log4j.appender.E = org.apache.log4j.DailyRollingFileAppender log4j.appender.E.layout = org.apache.log4j.PatternLayout log4j.appender.E.layout.ConversionPattern = [%-5p][%-22d{yyyy/MM/dd HH\:mm\:ssS}][%l]%n%m%n log4j.appender.E.Threshold = ERROR log4j.appender.E.Append = TRUE log4j.appender.E.File = ${bjgjqrcode.root}/WEB-INF/logs/running_error.log log4j.appender.E.DatePattern = '.'yyyy-MM-dd'.log' log4j.appender.E.Encoding = UTF-8 log4j.appender.I = org.apache.log4j.DailyRollingFileAppender log4j.appender.I.layout = org.apache.log4j.PatternLayout log4j.appender.I.layout.ConversionPattern = [%-5p][%-22d{yyyy/MM/dd HH\:mm\:ssS}][%l]%n%m%n log4j.appender.I.Threshold = INFO log4j.appender.I.Append = TRUE log4j.appender.I.File = ${bjgjqrcode.root}/WEB-INF/logs/running_info.log log4j.appender.I.DatePattern = '.'yyyy-MM-dd'.log' log4j.appender.I.Encoding = UTF-8log4j.appender.D = org.apache.log4j.DailyRollingFileAppender log4j.appender.D.layout = org.apache.log4j.PatternLayout log4j.appender.D.layout.ConversionPattern = [%-5p][%-22d{yyyy/MM/dd HH\:mm\:ssS}][%l]%n%m%n log4j.appender.D.Threshold = DEBUG log4j.appender.D.Append = TRUE log4j.appender.D.File = ${bjgjqrcode.root}/WEB-INF/logs/running_debug.log log4j.appender.D.DatePattern = '.'yyyy-MM-dd'.log' log4j.appender.D.Encoding =UTF-8最新文章
