log4j输出多个自定义路径的日志文件，动态配置路径

一、首先在Test.java定义：

private static Log logger1 = LogFactory.getLog("myTest1");

private static Log logger2 = LogFactory.getLog("myTest2");

eg：

public class Test {

private static Log logger1 = LogFactory.getLog("myTest1");

private static Log logger2 = LogFactory.getLog("myTest2");

/**
* @param args
*/
public static void main(String[] args) throws Exception{

logger1.info("11111111111");

logger2.info("22222222222");

}

}

二、然后在log4j.properties中加入以下配置:

log4j.logger.myTest1= DEBUG, test1
log4j.appender.test1=org.apache.log4j.FileAppender
log4j.appender.test1.File=${myweb.root}/WEB-INF/log/test1.log
log4j.appender.test1.layout=org.apache.log4j.PatternLayout
log4j.appender.test1.layout.ConversionPattern=%d %p [%c] - %m%n
　　
log4j.logger.myTest2= DEBUG, test2
log4j.appender.test2=org.apache.log4j.FileAppender
log4j.appender.test2.File=${myweb.root}/WEB-INF/log/test2.log
log4j.appender.test2.layout=org.apache.log4j.PatternLayout
log4j.appender.test2.layout.ConversionPattern=%d %p [%c] - %m%n
