日志文件自动压缩

使用 log4j 记录日志，每天0点进行分隔，由于日志文件较大，为节省空间，需要将历史文件自动压缩。需要使用 Apache Extras™ for Apache log4j™  的 org.apache.log4j.rolling.TimeBasedRollingPolicy 类进行配置。配置如下：

另外 logback 有许多优点，用它来实现压缩的配置如下：

	
		
		
			%d [%thread] %-5level %logger{36} - %msg%n
		
	

	
	
		log/app.log
		
			log/app.%d{yyyy-MM-dd}.log.gz
		
		
			%p [%t] %d %c: %m%n
