添加slf4j的的两种方法

1、代码添加:在类里添加​

public class MyInterceptor implements HandlerInterceptor {

 private static final Logger log = LoggerFactory.getLogger(MyInterceptor.class);
}

2、引入lombok依赖，注释添加：在类上添加

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

@Slf4j
public class MyInterceptor implements HandlerInterceptor {}
