Log4j configuration used

2010-12-15 来源：本站原创分类：Tech 人气：103

Log4j configuration commonly used in general can be used in two ways,. Properties and. Xml, give two simple examples below:
A, log4j.properties
# # # Set the domain corresponding to the level org.zblog INFO, DEBUG, WARN, ERROR and output to A1, A2 # #
log4j.category.org.zblog = ERROR, A1
log4j.category.org.zblog = INFO, A2
log4j.appender.A1 = org.apache.log4j.ConsoleAppender
# # # Set the output to A1, as ConsoleAppender (console) # #
log4j.appender.A1.layout = org.apache.log4j.PatternLayout
# # # Set the layout format of the output of A1 PatterLayout, (the flexibility to specify the layout mode) # #
log4j.appender.A1.layout.ConversionPattern =% d {yyyy-MM-dd HH: mm: ss, SSS} [% c] - [% p]% m% n
# # # Configure the log output format # #
log4j.appender.A2 = org.apache.log4j.RollingFileAppender
# # # Set the output to A2 to a file (the file size reaches the specified size when generating a new file) # #
log4j.appender.A2.File = E: / study/log4j/zhuwei.html
File location # # # # #
log4j.appender.A2.MaxFileSize = 500KB
# # # # # File size
log4j.appender.A2.MaxBackupIndex = 1
log4j.appender.A2.layout = org.apache.log4j.HTMLLayout
# # Specify the output methods using html
Second, log4j.xml
<? Xml version = "1.0" encoding = "GB2312"?>
<! DOCTYPE log4j: configuration SYSTEM "log4j.dtd">
<Log4j: Configuration xmlns: log4j = " http://jakarta.apache.org/log4j/ ">
<appender name="org.zblog.all">
<! - Set Channel ID: org.zblog.all and output mode: org.apache.log4j.RollingFileAppender ->
<param name="File" value="E:/study/log4j/all.output.log" /> <! - Set File parameters: the log output file name ->
<param name="Append" value="false" /> <! - Set whether to restart the service, the basis of the original log to add a new log ->
<param name="MaxBackupIndex" value="10" />
<layout>
<param name="ConversionPattern" value="%p (%c:%L)- %m%n" /> <! - project and set the output file format ->
</ Layout>
</ Appender>
<appender name="org.zblog.zcw">
<param name="File" value="E:/study/log4j/zhuwei.output.log" />
<param name="Append" value="true" />
<param name="MaxFileSize" value="10240" /> <! - set the file size ->
<param name="MaxBackupIndex" value="10" />
<layout>
<param name="ConversionPattern" value="%p (%c:%L)- %m%n" />
</ Layout>
</ Appender>
<logger name="zcw.log"> <! - set domain limitation that zcw.log log domain and the following are the corresponding output channel to the following ->
<level value="debug" /> <! - set the level ->
<appender-ref ref="org.zblog.zcw" /> <! - with the previous corresponding to the channel id ->
</ Logger>
<root> <! - set up to receive all output channels ->
<appender-ref ref="org.zblog.all" /> <! - with the previous corresponding to the channel id ->
</ Root>
</ Log4j: configuration>
Third, the configuration file loading method:
import org.apache.log4j.Logger;
import org.apache.log4j.PropertyConfigurator;
import org.apache.log4j.xml.DOMConfigurator;
public class Log4jApp {
public static void main (String [] args) {
DOMConfigurator.configure ("E: / study/log4j/log4j.xml ");// load. Xml file
/ / PropertyConfigurator.configure ("E: / study/log4j/log4j.properties ");// load. Properties files
Logger log = Logger.getLogger ("org.zblog.test");
log.info ("test");
}
}
Fourth, the project uses log4j
In web applications, configuration files can be loaded in a separate servlet, and configure the servlet in the web.xml in the application startup time to load. For many projects, you can set one output to each individual channel, so that everyone in the building in the Logger, use your own domain name, so that debugging information output to your log file.
Fifth, common output format
#-X Number: X information output left-justified;
#% P: log information level
#% D {}: log message generation time
#% C: location of log information (class name)
#% M: the log specific information
#% N: newline output log information
