springboot-aop简单使用

首先呢要引入spring-boot-starter-aop jar包

然后看下面代码：

@Aspect
@Component
public class HttpAspect {

    private final static Logger logger = LoggerFactory.getLogger(HttpAspect.class);


    @Pointcut("execution(public * com.xxx.controller.GirlController.*(..))") //拦截这个类的所有方法的不论传什么参数。
    public void log() {
    }

    @Before("log()")
    public void doBefore(JoinPoint joinPoint) {
        ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
        HttpServletRequest request = attributes.getRequest();

        //url
        logger.info("url={}", request.getRequestURL());

        //method
        logger.info("method={}", request.getMethod());

        //ip
        logger.info("ip={}", request.getRemoteAddr());

        //类方法
        logger.info("class_method={}", joinPoint.getSignature().getDeclaringTypeName() + "." + joinPoint.getSignature().getName());

        //参数
        logger.info("args={}", joinPoint.getArgs());
    }

    @After("log()")
    public void doAfter() {
        logger.info("222222222222");
    }

    @AfterReturning(returning = "object", pointcut = "log()")
    public void doAfterReturning(Object object) {
        logger.info("response={}", object.toString());
    }

}
