一、简介

支持日志框架：Java Util Logging, Log4J2 and Logback，默认是使用logback

对于日志的快捷方式：@Slf4j注解

注意：@Slf4j注解需要导入lombok包，pom如下：

     
         
      
       org.projectlombok
         
      
       lombok
      
     

对于log的connot resolve symbol log的红叉提示，解决：

  1.用快捷键Ctrl+Alt+S打开：Settings→Plugins→Browse repositories

 2.输入lom后选择Install，安装插件

logback配置方式

spring boot默认会加载classpath:logback-spring.xml或者classpath:logback-spring.groovy

使用自定义配置文件，配置方式为：

logging.config=classpath:logback-roncoo.xml

注意：不要使用logback这个来命名，否则spring boot将不能完全实例化

logback-spring.xml：
