如何用log4j创建多个不同内容的日志文件

Question

# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/home/dhanushka/Documents/log4j.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n

log4j.appender.testng=org.apache.log4j.RollingFileAppender
log4j.appender.testng.File=/home/dhanushka/Documents/TestNGlog.log
log4j.appender.testng.MaxFileSize=1MB
log4j.appender.testng.MaxBackupIndex=1
log4j.appender.testng.layout=org.apache.log4j.PatternLayout
log4j.appender.testng.layout.ConversionPattern=%d{ABSOLUTE} %-5p [%c{1}] %m%n

# Direct log messages to stdout
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} %-5p [%c{1}] %m%n

# Root logger option
log4j.rootLogger=INFO, file, admin, stdout, testng


# Log everything. Good for troubleshooting
log4j.logger.org.hibernate=INFO

# Log all JDBC parameters
log4j.logger.org.hibernate.type=ALL

public class VerifyAmenities {

private static Logger defaultLogger = Logger.getLogger("file");
private static Logger testNGlogger = Logger.getLogger("testng");
.
.
}
defaultLogger.info("This is default Logger");
testNGlogger.info("This is testNG Logger");

最后我找到了这样做的方法。

# Root logger option
log4j.rootLogger=TRACE, stdout, file

log4j.category.testngLogger=DEBUG, testng
log4j.additivity.testngLogger=false

在rootlogger中，它就像是所有日志的父。默认情况下继承。根记录器选项应该是这样的。
如果additivity设置为false，则它将永远不会转到rootlogger

在log4j.xml文件中，如下所示。

<logger name="testngLogger" additivity="false">
    <level value="DEBUG" />
    <appender-ref ref="testngLogger" />
</logger>

<root>
    <priority value="INFO" />
    <appender-ref ref="CONSOLE" />
    <appender-ref ref="fileLogger" />
</root>
