]]>Log4j 中更细粒度的控制调试等级http://www.blogjava.net/liuzheng/articles/175842.html刘铮 刘铮 Thu, 17 Jan 2008 01:58:00 GMThttp://www.blogjava.net/liuzheng/articles/175842.htmlhttp://www.blogjava.net/liuzheng/comments/175842.htmlhttp://www.blogjava.net/liuzheng/articles/175842.html#Feedback0http://www.blogjava.net/liuzheng/comments/commentRss/175842.htmlhttp://www.blogjava.net/liuzheng/services/trackbacks/175842.html log4j.logger.org.springframework=debug
log4j.logger.httpclient=INFO

这样表示有关org.springframework包和子包下面的类的调试等级为debug
httpclient包和子包的下面的类的调试等级为INFO
其他的为debug

比如在com.test包下面新建立个类为Test
在com.go下面新建立个类为Go
一般初始化log为
private static final Log log = LogFactory.getLog(Test.class);
private static final Log log = LogFactory.getLog(go.class);
如果这样设置
log4j.logger.com.test.Test=INFO
log4.logger.com.go.GO=WARN
那么这两个类的调试等级分别为INFO和WARN

]]>Log4j中常用的PatternLayout布局说明http://www.blogjava.net/liuzheng/articles/144305.html刘铮 刘铮 Tue, 11 Sep 2007 09:03:00 GMThttp://www.blogjava.net/liuzheng/articles/144305.htmlhttp://www.blogjava.net/liuzheng/comments/144305.htmlhttp://www.blogjava.net/liuzheng/articles/144305.html#Feedback0http://www.blogjava.net/liuzheng/comments/commentRss/144305.htmlhttp://www.blogjava.net/liuzheng/services/trackbacks/144305.htmllog4j.properties的一般配置方法如下：
仅仅配置的console的输出

log4j.rootLogger=INFo, A2

####
log4j.appender.A2=org.apache.log4j.ConsoleAppender
log4j.appender.A2.layout=org.apache.log4j.PatternLayout
log4j.appender.A2.layout.ConversionPattern=%p [%c] [%M] [%L]-%m%n



其中常用的字符代表的意思如下：
%表示output输入
p表示level
c表示调用的类
m表示log时的信息
n表示回车
M表示输出log时的信息的那个方法
F表示输出log时的信息的那个文件名
L表示输出log时的信息所在类的行数
WARNING Generating the caller class information can be excruciatingly
slow. Thus, the use of the C, F, l, L, and M conversion characters should be
avoided unless execution speed is not an issue.
