**1，logback-spring.xml编写（记得导入 slf4j 的依赖）：**

<?xml version="1.0" encoding="UTF-8"?>
    <configuration  scan="true" scanPeriod="10 seconds">
    
        <contextName>logback</contextName>

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

        </springProfile>
    
    </configuration>

**2，使用 @Slf4j 注解：**

@Slf4j
    public class BaseController {
    
    
        @ModelAttribute
        public void consoleLog(){
           log.info("参数1：{} , 参数2:{} " ,"参数1" ,"参数2");
        }
    }
