日志简化,不用个类引入lombok + Log4j2

pom配置

		<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-log4j2</artifactId>
        </dependency>
		 <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <version>1.14.8</version>
            <scope>provided</scope>
        </dependency>

• lombok只需要编译期生效,所以只用设置provided

加上@Log4j2的注解

@Log4j2
@Component
public class AuthorityInterceptor implements HandlerInterceptor {

用log写日志

log.debug("Debugging log");
		log.info("Info log");
		log.warn("Hey, This is a warning!");
		log.error("Oops! We have an Error. OK");
		log.fatal("Damn! Fatal error. Please fix me.");
