1、第一种直接配置在application.yml文件里，但这种配置简单，只能配置日志文件的输出路径和格式等，具体配置如下：

logging:
      pattern:
        console: "%d - %msg%n"
      path: /log/firstspringboot/

输出文件名字如下：

2、第二种，配置在logback.xml文件里，这种就可以做一些复杂的配置，比如可以区分info和error的日志，每天产生一个日志文件等，具体配置如下：

<?xml version="1.0" encoding="UTF-8" ?>
    
    <configuration>
    
        
        <appender name="consoleLog" class="ch.qos.logback.core.ConsoleAppender">
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>
                    %d - %msg%n
                </pattern>
            </layout>
        </appender>
    
        
        <appender name="fileInfoLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <filter class="ch.qos.logback.classic.filter.LevelFilter">
                <level>ERROR</level>
                <onMatch>DENY</onMatch>
                <onMismatch>ACCEPT</onMismatch>
            </filter>
            <encoder>
                <pattern>
                    %d - %msg%n
                </pattern>
            </encoder>
            
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                
                <fileNamePattern>/log/firstspringboot/info%d.log</fileNamePattern>
            </rollingPolicy>
        </appender>
    
        
        <appender name="fileErrorLog" class="ch.qos.logback.core.rolling.RollingFileAppender">
            <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
                <level>ERROR</level>
            </filter>
            <encoder>
                <pattern>
                    %d - %msg%n
                </pattern>
            </encoder>
            
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
                
                <fileNamePattern>/log/firstspringboot/error%d.log</fileNamePattern>
            </rollingPolicy>
        </appender>
    
        
        <root level="info">
            <appender-ref ref="consoleLog" />
            <appender-ref ref="fileInfoLog" />
            <appender-ref ref="fileErrorLog" />
        </root>
    
    </configuration>

输出文件如下：
