springboot使用log4j2

springboot 自带common.logging,并使用logback管理日志

所以要引进log4j2首先要禁用spring原本的日志系统

使用Gradle

configurations {

        compile.exclude group:'ch.qos.logback'

}

使用maven

   

        org.springframework.boot

        spring-boot-starter-logging

    

然后引入spring-boot-starter-log4j2，

compile group: 'org.springframework.boot', name: 'spring-boot-starter-log4j2', version:'1.5.2.RELEASE'

如果你的配置文件是yml写成的还要配置一个yaml

compile ('com.fasterxml.jackson.dataformat:jackson-dataformat-yaml')

下面干货来了

我们将log4j2.yml文件放置到resourse下，springboot将自动读取
