在不同环境中记录应用程序Log4j [英] Logging for application in different environment Log4j

问题描述

我正在使用Log4j开发日志框架。我不能找出如何为不同的环境，即开发，测试，分期和生产维护单独的日志文件。

I am developing a logging framework using Log4j. I am not able to figure out how to maintain separate log files for different environment, i.e., development, testing, staging and production.

推荐答案

p>首先，您需要为每个环境提供一个不同的log4j.xml副本。

Firstly you'll need a different copy of your log4j.xml for each environment.

将其命名为log4j-dev.xml，log4j-test.xml，log4j-stage.xml和log4j-prod.xml，每个都有自己的设置，如日志文件名和日志级别。

Lets call it log4j-dev.xml, log4j-test.xml, log4j-stage.xml and log4j-prod.xml each having their own settings like log file name and log levels.

然后，在服务器启动时将相应的文件作为系统属性传递，如下所示 -

You then pass in the corresponding file at the the server startup as a system property like below -

-Dlog4j.configuration=log4j-dev.xml

此网址提供了如何将此传递给Tomcat的示例。对于您要部署的任何服务器，此概念都是相同的。

This URL has the example on how to pass this for Tomcat. The concept is the same for whichever server you are deploying on.
