SentinelResourceAspect为什么没有total相关类 | Why there is not a "total" resource for all @SentinelResource occurrences?

读源代码（版本：`1.8.2` ）时， `sentinel-spring-webmvc-adapter-1.8.2.jar` 有提供 `com.alibaba.csp.sentinel.adapter.spring.webmvc.SentinelWebInterceptor` 和 `com.alibaba.csp.sentinel.adapter.spring.webmvc.SentinelWebTotalInterceptor`，位置如图：
1、为什么 `sentinel-annotation-aspectj-1.8.2.jar` 只提供 `com.alibaba.csp.sentinel.annotation.aspectj.SentinelResourceAspect`，没有total相关的类？
2、`annotation` 方式，总数如何统计？`@SentinelResource(value="xxx")` 配置一样的名字是否可以解决？是否有更好的方式？
3、`SentinelWebInterceptor` 与 `SentinelWebTotalInterceptor` 同时配置，是怎么计数的？

Compare SentinelResourceAspect in sentinel-annotation-aspectj-1.8.2.jar with SentinelWebInterceptor and SentinelWebTotalInterceptor in sentinel-spring-webmvc-adapter-1.8.2.jar. Trace how annotation-based resources and the two web interceptors are counted, then document whether equal @SentinelResource values aggregate and how simultaneous interceptor configuration behaves.
