springboot log4j2配置参考-highlight-IDE控制台彩色日志

导读

• 查看log4j官方样式说明，其中highlight相关说明如下图
• 查看ANSI COLOR NAME，如下图所示
  
• 关于windows下highlight不生效的问题说明

解决方法很简单，一个字：disableAnsi=“false”

开始配置

step1 maven

add log4j2 and exclude logback或log4j

<dependency>
    <groupId>org.springframework.bootgroupId>
    <artifactId>spring-boot-starter-log4j2artifactId>
dependency>

<dependency>  
    <groupId>org.springframework.bootgroupId>  
    <artifactId>spring-boot-starter-webartifactId>  
    <exclusions>
        <exclusion>  
            <groupId>org.springframework.bootgroupId>  
            <artifactId>spring-boot-starter-loggingartifactId>  
        exclusion>  
    exclusions>  
dependency> 

step2 application.properties

logging.config=classpath:log4j2.xml

step3 log4j2.xml

这里有针对windowns平台highlight生效的配置 disableAnsi=“false”
