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 handler, which runs a specific request-filter chain
Spring cloud builds the microservice architecture GateWay (API GateWay), springcloud Preface As mentioned in our previous blog, when service A needs to call service B, it only needs to obtain the registered instance of Service B from Eureka and then use Feign to call service B, ribbon is used to achieve load balancing. However, when we expose multiple services to
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
I. OverviewPrerequisites: Spring 5, Spring Boot 2 and Project Reactor.Spring Cloud Gateway is designed to provide a simple and efficient way to route to APIs and provide them with crosscutting concerns such as security, monitoring/metrics, and resiliency.Route: The basic building block of the routing gateway. It is defined by the ID, target URI, predicate collect
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
Spring Cloud (11): Service Gateway Zuul (filter) "Version Finchley" Posted in 2018-04-23 | updated on 2018-05-07 | In the previous article we learned about the basic functionality of Spring Cloud Zuul as a gateway: Routing (Router). In this article, we will focus on another core feature of Spring

Through the previous sharing, we learned about several core facilities of the microservices architecture, through which we can build a simple microservices architecture system. For example, through spring Cloud Eureka to build a highly available service registry and realize the registration and discovery of services;Load balance through the Spring cloud ribbon or feign, and fault-tolerant protection with sp

So far, we have introduced a lot of the content of Spring cloud, Ribbon, Hystrix, feign the knowledge that everyone is familiar with, we also mentioned in the previous micro-service is to split a large project into a number of small independent modules, And then through service management let these independent modules work together. So let's think about this. Two questions: 1. If there are many independent services in my micro-service that have to be
