首先logbok-spring.xml里面的内容
<?xml version="1.0" encoding="UTF-8"?>
<configuration><!-- 开发、测试环境 --><springProfile name="dev,test"><include resource="org/springframework/boot/logging/logback/base.xml" /><root level="INFO"><appender-ref ref="CONSOLE" /><appender-ref ref="FILE" /></root><logger name="org.springframework.web" level="DEBUG"/><logger name="org.springboot.sample" level="DEBUG" /><logger name="com.book_store.bookstore" level="DEBUG" /></springProfile><!-- 生产环境 --><springProfile name="pro"><logger name="org.springframework.web" level="INFO"/><logger name="org.springboot.sample" level="INFO" /><logger name="com.book_store.bookstore" level="ERROR" /></springProfile>
</configuration>然后再application.yml中配置
spring:profiles:#开发环境日志配置active: dev这样就是先springboot环境多配置了
中途知识补给
<include resource="org/springframework/boot/logging/logback/base.xml" />这个东西是springboot中自带的基础xml文件，本地jar看了看没有，去github开源的源码中找到了这个文件，官方地址：

https://github.com/spring-projects/spring-boot/blob/main/spring-boot-project/spring-boot/src/main/resources/org/springframework/boot/logging/logback/base.xml文件内容：
<?xml version="1.0" encoding="UTF-8"?><!--
Base logback configuration provided for compatibility with Spring Boot 1.1
--><included><include resource="org/springframework/boot/logging/logback/defaults.xml" /><property name="LOG_FILE" value="${LOG_FILE:-${LOG_PATH:-${LOG_TEMP:-${java.io.tmpdir:-/tmp}}}/spring.log}"/><include resource="org/springframework/boot/logging/logback/console-appender.xml" /><include resource="org/springframework/boot/logging/logback/file-appender.xml" /><root level="INFO"><appender-ref ref="CONSOLE" /><appender-ref ref="FILE" /></root>
</included>这里面的内容都是可以复写的，其中defaults也在上面的连接中
defaults.xml
<?xml version="1.0" encoding="UTF-8"?><!--

</included>root中的level就是输出级别
<root level="INFO"><appender-ref ref="CONSOLE" /><appender-ref ref="FILE" /></root>
