1、背景说明

最开始使用 SpringBoot 时，控制台日志是带彩色的，让人眼前一亮😄
后来彩色莫名丢失，由于影响不大，一直没有处理。

2、配置彩色

最近找到了解决方法（其实是因为自定义 logback.xml）：

spring:output:ansi:enabled: always	# 强制启用 ansi 输出
logging:pattern:# 控制台日志格式console: "%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(%5p) %clr(${PID:- }){magenta} %clr(%-40.40logger{39}){cyan} : %msg%n"

3、logback.xml

生产环境配置了三种日志：控制台、分钟文件、每日文件

<?xml version="1.0" encoding="UTF-8"?>
