SLF4J spingboot

注解使用 pom引入lombok

<dependency>
        <groupId>org.projectlombok</groupId>
        <artifactId>lombok</artifactId>
    </dependency>

在要使用的类上添加注解 @Slf4j

在该类中通过通过log进行打印日志

log.info("info....");

不使用注解使用方式

application.yml 配置

logging:
      pattern:
        console: "%d - %msg%n"       #控制台日志输出格式
    #  path: /usr/local/log/logger   #和file选用一个（logger输出日志地址）
      file: /usr/local/log/sell.log
      level:                         #日志级别
        com.test.LoggerTest: debug   #单独设置某个类的日志级别

logback-spring.xml 日志配置
