## **方案一：** ##

添加参数    -Dspring.output.ansi.enabled=ALWAYS

如下图所示：

## 方案二： ##

springboot默认是logback日志，初始构建日志是还有颜色的，但是由于某种操作之后颜色消失了，如何进行配置文件配置呢？

步骤如下：

相应目录resource下增加logback.xml

配置文件代码如下：

<?xml version="1.0" encoding="UTF-8"?>
    
    
    <configuration scan="true" scanPeriod="10 seconds">
    	
    
    	
    	<property name="LOG_HOME" value="logs" />
    	<property name="LOG_PREFIX" value="zuul-gateway" />
    
    	
    	<appender name="INFO_FILE"
    		class="ch.qos.logback.core.rolling.RollingFileAppender">
    		<File>${LOG_HOME}/${LOG_PREFIX}-info.log</File>
    		<rollingPolicy
    			class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
    			
    			<fileNamePattern>${LOG_HOME}/${LOG_PREFIX}-info-%d{yyyyMMdd}.log.%i
    			</fileNamePattern>
    			
    			<maxFileSize>100MB</maxFileSize>
    			<maxHistory>30</maxHistory>
    			<totalSizeCap>20GB</totalSizeCap>
    		</rollingPolicy>
    		<encoder>
    			
    			<Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36}
    				-%msg%n</Pattern>
    		</encoder>
    	</appender>
    
    	
    	<appender name="ERROR_FILE"
    		class="ch.qos.logback.core.rolling.RollingFileAppender">
    		<filter class="ch.qos.logback.classic.filter.ThresholdFilter">
    			<level>ERROR</level>
    		</filter>
    		<File>${LOG_HOME}/${LOG_PREFIX}-error.log</File>
    		<rollingPolicy
    			class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
    			
    			<fileNamePattern>${LOG_HOME}/${LOG_PREFIX}-error-%d{yyyyMMdd}.log.%i
    			</fileNamePattern>
    			
    			<maxFileSize>100MB</maxFileSize>
    			<maxHistory>30</maxHistory>
    			<totalSizeCap>20GB</totalSizeCap>
    		</rollingPolicy>
    		<encoder>
    			
    			<Pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36}
    				-%msg%n</Pattern>
    		</encoder>
    	</appender>
    
    	<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    		<encoder>
    			
    			<pattern>%yellow(%date{yyyy-MM-dd HH:mm:ss}) |%highlight(%-5level)  |%green(%logger:%line) |%black(%msg%n)</pattern>
    		</encoder>
    	</appender>
    
    	
    	<root level="INFO">
    		<appender-ref ref="STDOUT" />
    		<appender-ref ref="INFO_FILE" />
    		<appender-ref ref="ERROR_FILE" />
    	</root>
    
    </configuration>

stdout核心代码如下：其中yellow等颜色是对输出日志颜色的描述：

<pattern>%yellow(%date{yyyy-MM-dd HH:mm:ss}) |%highlight(%-5level)  |%green(%logger:%line) |%black(%msg%n)</pattern>

运行效果图：
