The use of the spring boot base for unified processing of request logs using AOP

Aspect-oriented (AOP) Aspect oriented programming is a programming paradigm that is independent of language and is a programming idea, which is one of the two core of spring. Do not know can see the net of the video tutorial. Here are the key codes that have been compiled after the individual learning video.
Adding AOP Dependencies

    <dependency>        <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-aop</artifactId> </dependency>

Create a processing file, add @Aspect annotations on the class, and then add the class to the spring container with @Component

Package com.xu.demo_springboot_01.aspect;Import Org.aspectj.lang.JoinPoint;Import org.aspectj.lang.annotation.*;Import Org.slf4j.Logger;Spring comes with a log frameImport Org.slf4j.LoggerFactory;Import org.springframework.stereotype.Component;Import Org.springframework.web.context.request.RequestContextHolder;Import org.springframework.web.context.request.ServletRequestAttributes;Import Javax.servlet.http.HttpServletRequest;@Aspect@ComponentBring this class into the spring container.PublicClassHttpaspect {PrivateFinalstatic Logger Logger = Loggerfactory.getlogger (Httpaspect.class);parameter is the class name that is currently used@Pointcut ("Execution (Public * com.xu.demo_springboot_01.controller.) girlcontroller.* (..))

注：//记录日志变量的方法logger.info("url ={}",request.getRequestURI());//逗号后面跟要记录的变量//记录日志常量logger.info("url");
