为什么Log4j认为我的项目在Servlet环境中运行 [英] Why Log4j thinks my project run in Servlet Environment

问题描述

我有一个简单的Java项目(Maven).这将构建一个jar，然后在其上执行main方法.但是，当我在项目上运行 mvn clean test 时，我从log4j看到一条日志行，

I have a simple java project (maven). Which builds a jar and we execute the main method on it. But when I run mvn clean test on the project I get a log line from log4j saying

INFO Log4j appears to be running in a Servlet environment, but there's no log4j-web module available. If you want better web container support, please add the log4j-web JAR to your web archive or server lib directory.

log4j2.xml 文件位于 src/main/resources/log4j2.xml 中.

有什么想法吗?

推荐答案

如果您的类路径中有 servlet-api Jar，则Log4j会认为您正在Servlet容器中运行.具体来说，它将查找 javax.servlet.ServletContext 的存在.如果您的应用程序不在Servlet容器中运行，那么您实际上就不需要该Jar.

If you have the servlet-api Jar in your classpath, Log4j is going to think you are running in a Servlet container. Specifically, it looks for the presence of javax.servlet.ServletContext. If your application is not running in a Servlet container, then you really shouldn't need that Jar.
