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>
