the class SentinelAutoConfiguration method addSpringMvcInterceptor.

/**
 * 接口请求后会被拦截到控制台的---簇点链路上， 可以不适用@SentinelResource注解， 区别是， 如果接口调用链上没有生命是的@SentinelResource资源，
 * 那么就将最外层接口入口层（即方法的@RequestMapping）作为资源且不会往下生成资源链。而如果@RequestMapping方法调用了某个@SentinelResource资源，
 * 则会在入口层往下生成资源链路
 * <p>
 * 格式如下
 * 无资源映射
 * /helloA
 * <p>
 * 有资源映射
 * /helloB
 * -- hello(如果这个方法声明了@SentinelResource的话)
 *
 * @param registry
