of the Eureka-client service, and can also observe its load balancing effect by initiating multiple eureka-client services.From now on, I will record the process and the essence of the recently developed Springcloud micro-service cloud architecture, and help more friends who are interested in developing the Spring cloud framework, hoping to help more good schola
On the spring cloud Registry and the client registration, so this article is about how services and services are calledNot set up a small partner please refer to my previous blog: Idea Quick build Spring cloud-Registration Center and RegistrationBased on the previous article I built a client-side
DcClient dcClient; @GetMapping("/consumer") public String dc() { return dcClient.consumer(); }}The way to implement service invocation through spring Cloud feign is much simpler, with the interface defined by @feignclient to unify the life we need to rely on for the MicroServices interface. And in the specific use of the call to the local meth

shouldFilter: Determines whether the filter needs to be executed. Here we return directly true , so the filter will take effect for all requests. In practice we can use this function to specify the effective range of the filter.
run: The specific logic of the filter. Here we ctx.setSendZuulResponse(false) can further optimize our return by making Zuul filter the request, not routing it, and then by ctx.setResponseStatus
return true, so the filter will take effect for all requests. In practice we can use this function to specify the effective range of the filter.Run: The specific logic of the filter. Here we use Ctx.setsendzuulresponse (false) to make Zuul filter the request, do not route it, and then set its return error code via CTX.SETRESPONSESTATUSCODE (401). Of course, we can also further optimize our return, for example, by Ctx.setresponsebody (body) to return the body content to edit and so on.After impl
selecting instances and stitching URLs through loadbalancerclient and initiating requests directly through Resttemplate.@RestControllerpublic class DcController { @Autowired RestTemplate restTemplate; @GetMapping("/consumer") public String dc() { return restTemplate.getForObject("http://eureka-client/dc", String.class); }}As you can see here, in addition to removing the original logic related to Loadbalancerclient, our first URL parameter is somewhat special for resttempla
