Log4j日志切割实践篇

标签：log4j   hibernate   

1：需要的jar

log4j-1.2.14.jar

tomcat-juli-adapters.jar

tomcat-juli.jar

2：src下添加log4j.properties

<span style="font-size:18px;">log4j.rootLogger=debug, stdout, log, errorlog
#log4j.addivity.org.apache=true  

 
###Console ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern =  %d{ABSOLUTE} [ %p ] [ %C{1}.java :%L(%M)] %m%n

### Log ###  
log4j.appender.log = org.apache.log4j.DailyRollingFileAppender
log4j.appender.log.File = c:/logs/osd/log.log
log4j.appender.log.Append = true
log4j.appender.log.Threshold = DEBUG
log4j.appender.log.DatePattern='.'yyyy-MM-dd
log4j.appender.log.layout = org.apache.log4j.PatternLayout
log4j.appender.log.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss} [ %p ] [ %C{1}.java :%L(%M)]  %m%n

### Error ###
log4j.appender.errorlog = org.apache.log4j.DailyRollingFileAppender
log4j.appender.errorlog.File = c:/logs/osd/errorlog.log
log4j.appender.errorlog.Append = true
log4j.appender.errorlog.Threshold = ERROR 
log4j.appender.errorlog.DatePattern='.'yyyy-MM-dd
log4j.appender.errorlog.layout = org.apache.log4j.PatternLayout
log4j.appender.errorlog.layout.ConversionPattern =%-d{yyyy-MM-dd HH:mm:ss} [ %p ] [ %C{1}.java :%L(%M)] %m%n




</span>

<span style="font-size:18px;">
</span>

<span style="font-size:18px;background-color: rgb(102, 255, 255);">3：使用方法</span>

<span style="font-size:18px;"></span><pre name="code" class="java">public class BaseApi {
	private static Logger logger = Logger.getLogger(BaseApi.class);

	public BaseApi() throws Throwable {
		logger.debug(getClass().getSimpleName() + " has created!");
	}

}

<span style="font-size:18px;">(1)log4j.rootLogger=debug 表示日志输出的最低级别</span>

<span style="font-size:18px;">
</span>

<span style="font-size:18px;">(2)如果使用Hibernate框架的话，还需要屏蔽Hibernate带的日志，否则很难跟踪日志。</span>

<span style="font-size:18px;">第一步： <property name="hibernate.show_sql" value="false" />
</span>

<span style="font-size: 18px;">第二步：Log4j配置文件中加入</span>
