23.3 配置log4j

（1）在maven项目的/src/main目录下新建resources目录（与java同级别），然后右键单击resources目录，选择“Mark Directory As”，并设置为Resources Root。

（2）在resources目录下新建log4j2.properties文件，编辑内容如下。

appender.console.type = console
appender.console.name = console
appender.console.layout.type = PatternLayout
rootLogger.level = info
rootLogger.appenderRef.console.ref =console
