## 写在前面 ##

有时候，我们需要修改springboot 默认的日志输出，包括日志等级颜色区分、日志输出位置、日志文件格式（按照每天，最大空间等）这里可供参考。

很简单，不需要引额外的包，因为springboot -starter-web中起步依赖中，已经引入了lagback,slt4j,log4j等。

只需在已有的项目中，添加两个配置，一个配置类，还有一个xml配置即可。

## 一、添加配置 ##

### 1.1、配置类 ###

package com.github.jetty.config;
    
    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;
            }
        }
    }

### 1.2、logback.xml ###

<?xml version="1.0" encoding="UTF-8"?>
    
    <configuration scan="true" scanPeriod="60 seconds" debug="false">
        
        <conversionRule conversionWord="customcolor" converterClass="com.github.jetty.config.LogbackColorful"/>

                </pattern>
            </encoder>
    
        </appender>
    
        
        
        <appender name="appLogAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">

            <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
                <fileNamePattern>${LOG_HOME}/${appName}-%d{yyyy-MM-dd}-%i.zip</fileNamePattern>
                <MaxHistory>30</MaxHistory>
                <maxFileSize>50MB</maxFileSize>
                <totalSizeCap>2GB</totalSizeCap>
            </rollingPolicy>
            
            <layout class="ch.qos.logback.classic.PatternLayout">
                <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [ %thread ] - [ %-5level ] [ %logger{50} : %line ] - %msg%n</pattern>
            </layout>
        </appender>
        
        <springProfile name="dev,test">
            <logger name="org.springframework.web" level="INFO"/>
            <logger name="com.github.jetty" level="INFO"/>
            
            <logger name="com.github.jetty" level="DEBUG"/>
        </springProfile>
    
        
        <springProfile name="prod">
            
            
            <logger name="org.springframework.web" level="ERROR"/>
            <logger name="com.github.jetty" level="ERROR"/>
            
    
        </springProfile>
    
    
        
        <root level="info">
            
            <appender-ref ref="CONSLOG"/>
            
            <appender-ref ref="appLogAppender"/>
        </root>
    </configuration>

## 二、启动测试 ##

日志记录文件，如下
