Can Sentinel support feign ?

[xiejiashuai]

RestTemplate 使用起来太不友好了，不如Feign方便。可否考虑支持下Feign。

Spring Framework RestTemplate is not convenient when used , can consider supproting Feign.

Sentinel 目前对于有线程切换的行为处理还不大完善，待 Sentinel 完善支持后会评估支持方案。

Sentinel currently does not have a good deal of behavior for thread switching, we will evaluate it after Sentinel supports this scenario.

A simple FeignClient like this:

@FeignClient(name = "service-provider", fallback = EchoServiceFallback.class)
public interface EchoService {
	@RequestMapping(value = "/echo/{str}", method = RequestMethod.GET)
	String echo(@PathVariable("str") String str);
}

The resource name of method echo is: GET:http://service-provider/echo/{str} and we use SphU to handle it:

Entry entry = SphU.entry(resourceName, EntryType.OUT, 1, args);

So we can use any rules, including ParamFlowRule.
