Log：logback.xml配置

　　Maven 管理的项目，在src/main/resources下新建logback.xml文件。

1. logback.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<configuration scan="true" scanPeriod="1 seconds" debug="false">
     <timestamp key="bySecond" datePattern="yyyyMMdd'T'HHmmss" />
     <contextName>${bySecond}</contextName>

     <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
           <encoder>
<!--            <pattern>%-4relative [%thread] %-5level %logger{35} - %msg %n</pattern> -->
                <pattern>logbak: %d{HH:mm:ss.sss} %logger{36} - %msg%n</pattern>
           </encoder>
     </appender>
     
     <logger name="org.springframework.web" level="DEBUG"/>
     <root level="info">
           <appender-ref ref="console"/>
     </root>
     
</configuration>

2. 在pom.xml导入logback依赖包

<properties>
	<logback.version>1.2.3</logback.version>
</properties>
<!-- logback -->
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-core</artifactId>
    <version>${logback.version}</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>${logback.version}</version>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-access</artifactId>
    <version>${logback.version}</version>
</dependency>
