log4j.properties文件 - 同一个类中的多个记录器 [英] log4j.properties file - multiple loggers in same class

问题描述

我想在我的应用程序中有两个不同的 log4j 记录器，并且在他们写入尊重日志的内容之间没有重叠。

I would like to have two different log4j loggers in my application, and for there to be no "overlap" between the content they write to their respect logs.

例如：

• Logger1写入与一组系统相关的INFO事件事件


• Logger2写入与另一组系统事件相关的INFO事件


• 两次日志中不应出现任何条目

我的log4j.properties如下：

My log4j.properties is as follows:

log4j.rootLogger=DEBUG, stdout
log4j.logger.org.apache=DEBUG, stdout
log4j.logger.xdasLogger=DEBUG, xdas

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%m%n

log4j.appender.xdas=org.apache.log4j.ConsoleAppender
log4j.appender.xdas.layout=org.apache.log4j.PatternLayout
log4j.appender.xdas.layout.ConversionPattern=%d %-5p %c - %m%n

我的Java代码如下：

My Java code is as follows:

public static void main(String[] args) {
    PropertyConfigurator.configure(Client.class
            .getResource("/log4j.properties"));
    xdasLogger = Logger.getLogger("xdasLogger");
    logger = Logger.getLogger(Client.class);

    logger.info("normal");
    xdasLogger.info("xdas");
}

但我的控制台输出如下：

But my console output is as follows:

normal
2012-06-28 09:52:44,580 INFO  xdasLogger - xdas
xdas

请注意， logger 和 xdasLogger都会记录xdas ，这是不受欢迎的。

Note that "xdas" is logged by both logger and xdasLogger, which is undesirable.

有谁知道我需要将哪些更改放入我的log4j.properties以将控制台输出更改为以下内容？

Does anyone know what changes I need to put into my log4j.properties to change the console output to the following?

normal
2012-06-28 09:52:44,580 INFO  xdasLogger - xdas

解决方案（取自已接受的答案）：

log4j.rootLogger=DEBUG, stdout
log4j.logger.org.apache=DEBUG, stdout
log4j.logger.xdasLogger=DEBUG, xdas

log4j.additivity.org.apache=false
log4j.additivity.xdasLogger=false

log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%m%n

log4j.appender.xdas=org.apache.log4j.ConsoleAppender
log4j.appender.xdas.layout=org.apache.log4j.PatternLayout
log4j.appender.xdas.layout.ConversionPattern=%d %-5p %c - %m%n

推荐答案

尝试将记录器的可加性设置为false。这将避免传播到rootLogger。

Try setting the additivity of the loggers to false. This will avoid the propagation to the rootLogger.

log4j.additivity.org.apache=false
log4j.additivity.xdasLogger=false
