8.spring boot 与aop

• 添加maven依赖

    org.springframework.boot
    spring-boot-starter-aop

• 添加切面

@Aspect
@Component
public class LogAspect {

    Logger logger = LoggerFactory.getLogger(this.getClass());

    @Around("execution(* com.yang.controller.*.*(..))&&@annotation(apiOperation)")
    public Object around(ProceedingJoinPoint joinPoint, ApiOperation apiOperation) throws Throwable {
        StringBuilder logInfo = new StringBuilder("用户访问了：");

        Class controller = joinPoint.getThis().getClass();
        Api api = controller.getAnnotation(Api.class);
        if(api!=null){
            logInfo.append(api.value());
        }

        String value = apiOperation.value();
        logInfo.append("-------"+value);

        logger.info(logInfo.toString());

        return joinPoint.proceed();
    }
}
