①：引入依赖 配置yml

<!-- 引入日志框架 -->
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
</dependency>

logging:
  level:
    com.example: info
  pattern:
    console: "%d{yyyy-MM-dd HH:mm:ss} [%thread] %-5level %logger{36} - %msg%n"

②：创建日志配置类

import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.spi.ILoggingEvent;
import ch.qos.logback.core.pattern.color.ANSIConstants;
import ch.qos.logback.core.pattern.color.ForegroundCompositeConverterBase;

public class LogbackColorful extends ForegroundCompositeConverterBase<ILoggingEvent> {

    @Override
    protected String getForegroundColorCode(ILoggingEvent event) {
        Level level = event.getLevel();
        switch (level.toInt()) {
            //ERROR等级为红色
            case Level.ERROR_INT:
                return ANSIConstants.RED_FG;
            //WARN等级为黄色
            case Level.WARN_INT:
                return ANSIConstants.YELLOW_FG;
            //INFO等级为蓝色
            case Level.INFO_INT:
                return ANSIConstants.BLUE_FG;
            //DEBUG等级为绿色
            case Level.DEBUG_INT:
                return ANSIConstants.GREEN_FG;
            //其他为默认颜色
            default:
                return ANSIConstants.DEFAULT_FG;
        }
    }
}

③：logback-spring.xml

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