自定义SpringBoot自带的logback配置

1.在resources目录下创建文件logback-spring.xml

<?xml version="1.0" encoding="UTF-8"?>
 
<configuration scan="true" scanPeriod="60 seconds">

	<springProperty scope="context" name="spring.application.name" source="spring.application.name"/>
 
	<!-- 定义参数 -->
	<property name="log.lever" value="debug" />
	<property name="log.maxHistory" value="365" />
 	<property name="log.filePath" value="logs"></property>
<!-- 	如果这里不想写死C盘，那么上面的配置，系统会自动在项目所在的盘符创建文件夹 -->
<!--	<property name="log.filePath" value="C:/{spring.application.name}_log"></property>-->
<!-- 	<property name="log.pattern" value="%-12(%d{yyyy-MM-dd HH:mm:ss.SSS}) |-%-5level [%thread] %c [%L] -| %msg%n" /> -->
	<property name="log.pattern" value="%-12(%d{MM-dd HH:mm:ss}) %c [%L] | %msg%n" />
 
	<!-- 控制台设置 -->
