我用的是springboot2.1.1

springboot提供日志打印的方式非常直接

名字对应，放到resource下

即可，内容：

<?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{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} -
    				%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{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} -
    				%msg%n
    			</pattern>
    		</encoder>
    		
    		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    			
    			<fileNamePattern>/logs/xynph/shangchao/log/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{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} -
    				%msg%n
    			</pattern>
    		</encoder>
    		
    		<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    			
    			<fileNamePattern>/logs/xynph/shangchao/error/error.%d.log
    			</fileNamePattern>
    		</rollingPolicy>
    	</appender>
    
    	<root level="info">
    		<appender-ref ref="consoleLog" />
    		<appender-ref ref="fileInfoLog" />
    		<appender-ref ref="fileErrorLog" />
    	</root>
    
    </configuration>

路径前面如果加斜杠/，会自动设置为绝对路径，win平台下日志在当前jar包盘首，linux在首目录。

上面配置打印的日志显示效果如下：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FpbmdjaGVuZzE1Nw_size_16_color_FFFFFF_t_70][]

另外要更换springboot启动图只需要添加banner.txt文件即可，

例子：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FpbmdjaGVuZzE1Nw_size_16_color_FFFFFF_t_70 1][]
