问题描述
我正在使用 Log4j 开发日志框架.我不知道如何为不同的环境(即开发、测试、暂存和生产)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
首先，您需要为每个环境准备一份不同的 log4j.xml 副本.
Firstly you'll need a different copy of your log4j.xml for each environment.
我们称之为 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入，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
这个 URL 有关于如何将它传递给 Tomcat 的示例.无论您部署在哪台服务器上，这个概念都是一样的.
This URL has the example on how to pass this for Tomcat. The concept is the same for whichever server you are deploying on.
