Springcloud (10): Service Gateway Zuul
In the previous article we introduced the Eureka used for service registration in discovery, feign support service invocation and balance load, hystrix processing services to fuse to prevent failure spread, Spring Cloud Config Service cluster Configuration center, it seems that a micro-service framework has been completed.
We are still less concerned about the externa
How Spring Cloud Gateway worksThe client makes a request to Spring Cloud Gateway and, if the request matches the route defined by the gateway program, sends it to the Gateway Web handle
Spring Cloud (10): Service Gateway Zuul (routing) "version Finchley" Posted in 2018-04-23 | updated on 2018-05-09 | With the introduction of several core components in Spring Cloud, we can already build a brief microservices architecture, perhaps like this:We implemented service registries and service registration and discovery using the Eureka in spring
in a traditional servlet container or be built as a war.Three, the principle of workThe client makes a request to the spring Cloud Gateway. If the gateway handler mapping determines that the request matches the route, it is sent to the gateway Web handler. This handler is r
This essay goes on to learn a more important Component API Gateway service in MicroServices. When we finally have to provide external access to the micro-service architecture, we need a unified access portal, to hide our internal service URL details, which is a bit like the concept of the gateway in the LAN, this is the API Gateway Service has emerged. API

In addition to the service Routing and load balancing function, the service gateway

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
