logback的日志文件中出现大量的ESC符号

        在使用若依的springboot项目时，发现控制台日志没有颜色，就想着加一下颜色，然后就修改logback.xml，增加%highlight、%cyan、%red等等，然后控制台就有颜色了。

问题是：日志文件中出现了大量的ESC，如下图：

 原因的话，可以参考一下这个：https://blog.csdn.net/shichen2010/article/details/83031418

解决思路：

就是控制台打印用颜色标记，打印到文件去掉颜色标记，也就是说至少配置两套pattern，完整logback.xml如下：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>
    
    <property name="log.path" value="/home/ruoyi/logs" />
    
    <property name="log.pattern" value="%d{yyyy-MM-dd HH:mm:ss.SSS} %highlight(%5p) %magenta(${PID}) [%16.16t] %cyan(%-40.40logger{39}): %msg%n" />
    <property name="log.file" value="%d{yyyy-MM-dd HH:mm:ss.SSS} %5p ${PID} [%16.16t] %-40.40logger{39}: %msg%n" />

            <maxHistory>60maxHistory>
        rollingPolicy>
        <encoder>

        encoder>
    appender>
    
    
    <logger name="com.ruoyi" level="info" />
    
    <logger name="org.springframework" level="warn" />

    <root level="info">
        <appender-ref ref="console" />
    root>
    
    
    <root level="info">
        <appender-ref ref="file_info" />
        <appender-ref ref="file_error" />
    root>
    
    
    <logger name="sys-user" level="info">
        <appender-ref ref="sys-user"/>
    logger>
configuration> 

然后就没问题了
