项目中统一日志处理

统一日志处理

默认情况下springboot从控制台打印出来的日志级别只有INFO及以上的，

可以进行配置

日志等级

OFF , FATAL , ERROR , WARN , INFO ,DEBUG, ALL

#日志级别设置  仅在控制台输出
logging.level.root = WARN

23.1 统一日志处理（logback）

1. 删除配置文件中的日志配置

   #设置日志级别  仅在控制台输出
   #logging.level.root = INFO
   #mybatis日志
   #mybatis-plus.configuration.log-impl=org.apache.ibatis.logging.stdout.StdOutImpl
   

   2.resources文件中创建logback-spring.xml

   
   <configuration  scan="true" scanPeriod="10 seconds">

       <property name="CONSOLE_LOG_PATTERN"
                 value="%yellow(%date{yyyy-MM-dd HH:mm:ss}) |%highlight(%-5level) |%blue(%thread) |%blue(%file:%line) |%green(%logger) |%cyan(%msg%n)"/>

   3.异常信息处理

   1. 全局异常变量配置中加@Slf4j注解

   2. log.error(e.getMessage());
