详解关于tomcat切割catalina.out日志的三种方式

1.log4j进行日志切分

1）准备三个包：log4j-1.2.17.jar      tomcat-juli.jar      tomcat-juli-adapters.jar 放到tomcat的lib目录或者是工程的WEB_INF/lib下，

2）在lib目录下新建log4j.properties，加入以下内容

log4j.rootLogger = INFO, CATALINA # Define all the appenderslog4j.appender.CATALINA = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.CATALINA.File = ${catalina.base}/logs/catalinalog4j.appender.CATALINA.Append = truelog4j.appender.CATALINA.Encoding = UTF-8# Roll-over the log once per daylog4j.appender.CATALINA.DatePattern = '.'yyyy-MM-dd'.log'log4j.appender.CATALINA.layout = org.apache.log4j.PatternLayoutlog4j.appender.CATALINA.layout.ConversionPattern = %d [%t] %-5p %c- %m%n log4j.appender.LOCALHOST = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.LOCALHOST.File = ${catalina.base}/logs/localhostlog4j.appender.LOCALHOST.Append = truelog4j.appender.LOCALHOST.Encoding = UTF-8log4j.appender.LOCALHOST.DatePattern = '.'yyyy-MM-dd'.log'log4j.appender.LOCALHOST.layout = org.apache.log4j.PatternLayoutlog4j.appender.LOCALHOST.layout.ConversionPattern = %d [%t] %-5p %c- %m%n log4j.appender.MANAGER = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.MANAGER.File = ${catalina.base}/logs/managerlog4j.appender.MANAGER.Append = truelog4j.appender.MANAGER.Encoding = UTF-8log4j.appender.MANAGER.DatePattern = '.'yyyy-MM-dd'.log'log4j.appender.MANAGER.layout = org.apache.log4j.PatternLayoutlog4j.appender.MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n log4j.appender.HOST-MANAGER = org.apache.log4j.DailyRollingFileAppenderlog4j.appender.HOST-MANAGER.File = ${catalina.base}/logs/host-managerlog4j.appender.HOST-MANAGER.Append = truelog4j.appender.HOST-MANAGER.Encoding = UTF-8log4j.appender.HOST-MANAGER.DatePattern = '.'yyyy-MM-dd'.log'log4j.appender.HOST-MANAGER.layout = org.apache.log4j.PatternLayoutlog4j.appender.HOST-MANAGER.layout.ConversionPattern = %d [%t] %-5p %c- %m%n log4j.appender.CONSOLE = org.apache.log4j.ConsoleAppenderlog4j.appender.CONSOLE.Encoding = UTF-8log4j.appender.CONSOLE.layout = org.apache.log4j.PatternLayoutlog4j.appender.CONSOLE.layout.ConversionPattern = %d [%t] %-5p %c- %m%n # Configure which loggers log to which appenderslog4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost] = INFO, LOCALHOSTlog4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager] =/ INFO, MANAGERlog4j.logger.org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager] =/ INFO, HOST-MANAGER
