web项目 log4j2 指定配置文件路径

pom.xml需要额外引入的jar:

         <dependency>
            <groupId>org.apache.logging.log4j</groupId>
            <artifactId>log4j-web</artifactId>
            <scope>runtime</scope>
        </dependency> 

web.xml:

    <context-param>
        <param-name>log4jConfiguration</param-name>
        <param-value>"log4j2.xml所在目录"/log4j2.xml</param-value>
    </context-param>

    <listener>
        <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>
    </listener>
