程序包 com.alibaba.csp.sentinel.adapter.spring.webmvc

类 AbstractSentinelInterceptor

java.lang.Object

com.alibaba.csp.sentinel.adapter.spring.webmvc.AbstractSentinelInterceptor

所有已实现的接口:

org.springframework.web.servlet.HandlerInterceptor

直接已知子类:

SentinelWebInterceptor, SentinelWebTotalInterceptor

public abstract class AbstractSentinelInterceptor
extends Object
implements org.springframework.web.servlet.HandlerInterceptor

Since request may be reprocessed in flow if any forwarding or including or other action happened (see ServletRequest.getDispatcherType()) we will only deal with the initial request. So we use reference count to track in dispathing "onion" though which we could figure out whether we are in initial type "REQUEST". That means the sub-requests which we rarely meet in practice will NOT be recorded in Sentinel.

How to implement a forward sub-request in your action:

 initalRequest() {
     ModelAndView mav = new ModelAndView();
     mav.setViewName("another");
     return mav;
 }
 

从以下版本开始:

1.7.1
