2,在src/main/resources目录下,配置log4j2.xml
    <?xml version="1.0" encoding="UTF-8"?>
<Configuration status="WARN">
    <Appenders>
        <Console name="Console" target="SYSTEM_OUT">
            <PatternLayout pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
        </Console>
    </Appenders>
    
    <Loggers>
        <Logger name="org.springframework" level="info">
            <AppenderRef ref="Console" />
        </Logger>
        <Root level="debug">
<!--              这儿为trace表示什么都可以打印出来了,其他几个级别分别为：TRACE、DEBUG、INFO、WARN、ERROR和FATAL -->
            <AppenderRef ref="Console" />
        </Root>
    </Loggers>
</Configuration>

3,在web.xml中配置监听器与过滤器
      <!-- Log4j2监听器 -->
   <listener>
    <listener-class>org.apache.logging.log4j.web.Log4jServletContextListener</listener-class>
  </listener>

<!-- Log4j2过滤器 -->
<filter>
    <filter-name>log4jServletFilter</filter-name>
    <filter-class>org.apache.logging.log4j.web.Log4jServletFilter</filter-class>
</filter>
<filter-mapping>
        <filter-name>log4jServletFilter</filter-name>
        <url-pattern>/*</url-pattern>
        <dispatcher>REQUEST</dispatcher>
