因Springboot默认已集成了Logback框架，所以直接配置logback.xml文件即可（[多环境配置文件用法教程][Link 1]）

<?xml version="1.0" encoding="UTF-8"?>
    <configuration>
    	
    	
    	<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    		<encoder>
    			<pattern>%d [%t] [%c] [%p] (%file:%line\)- %m%n</pattern>
    			<charset>UTF-8</charset>
    		</encoder>
    	</appender>
    	
    	<appender name="baselog"
    		class="ch.qos.logback.core.rolling.RollingFileAppender">
    		<File>log/run.log</File>
    		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    			<fileNamePattern>log/run.log.%d.%i</fileNamePattern>
    			<timeBasedFileNamingAndTriggeringPolicy
    				class="ch.qos.logback.core.rolling.SizeAndTimeBasedFNATP">
    				
    				<maxFileSize>64 MB</maxFileSize>
    			</timeBasedFileNamingAndTriggeringPolicy>
    			
    			<maxHistory>7</maxHistory>
    		</rollingPolicy>
    		<encoder>
    			<pattern>
    				%d [%t] [%c] [%p] (%file:%line\)- %m%n
    			</pattern>
    			<charset>UTF-8</charset> 
    		</encoder>
    	</appender>
    	<root level="INFO">
    		<appender-ref ref="STDOUT" />
    	</root>
    	
    	<logger name="com.md" level="DEBUG">
    		<appender-ref ref="baselog" />
    	</logger>
    </configuration>

相关参数含义，可见配置文件内的详细解释说明

# 案例说明 #

代码使用

package com.md.demo.rest;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.web.bind.annotation.GetMapping;
    import org.springframework.web.bind.annotation.RestController;
    
    /**
     * @author Minbo
     */
    @RestController
    public class InitRest {
    
    	protected static Logger logger = LoggerFactory.getLogger(InitRest.class);
    
    	/**
    	 * http://localhost:9090/hello
    	 * 
    	 * @return
    	 */
    	@GetMapping("/hello")
    	public String hello() {
    		logger.info("hello");
    		return "Hello greetings from spring-boot2-logback";
    	}
    }

启动项目，访问接口：[http://localhost:9090/hello][http_localhost_9090_hello]
