搭建SSM框架运行，打印输出

ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...

报错提示需要添加 log4j-core的jar包

<!-- https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-core -->
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.11.1</version>
</dependency>

添加过maven文件后再次启动

又报错误

ERROR StatusLogger No Log4j 2 configuration file found. Using default configuration (logging only errors to the console), or user programmatically provided configurations. Set system property 'log4j2.debug' to show Log4j 2 internal initialization logging. See https://logging.apache.org/log4j/2.x/manual/configuration.html for instructions on how to configure Log4j 2

这时需要在classpath中添加log4j2.xml文件

<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="warn">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="[%-5p] %d %c - %m%n" />
        </Console>
        <File name="File" fileName="dist/my.log">
            <PatternLayout pattern="%m%n" />
        </File>
    </Appenders>

    <Loggers>
        <Logger name="mh.sample2.Log4jTest2" level="INFO">
            <AppenderRef ref="File" />
        </Logger>
        <Root level="INFO">
            <AppenderRef ref="Console" />
        </Root>
    </Loggers>
</Configuration>

再次运行
