1、在resources下添加logback.xml配置文件：

2、logback.xml：

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="10 seconds">

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <layout class="ch.qos.logback.classic.PatternLayout">
            <Pattern>
                %d{yyyy-MM-dd HH:mm:ss} %-5level %logger{36} - %msg%n
            </Pattern>
        </layout>
    </appender>

    <logger name="org.springframework.web" level="error" additivity="false">
        <appender-ref ref="STDOUT"/>
    </logger>
    <!--设置debug功能-->
    <logger name="com.xhy" level="debug" additivity="true">
        <appender-ref ref="STDOUT"/>
    </logger>

    <root level="error">
        <appender-ref ref="STDOUT"/>
    </root>

</configuration>
