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 the client at the same time, how does the client call our exposed services? If we want to add security authentication, permission cont

API Gateway Service: Spring Cloud Zuul API Gateway is a more intelligent application server, it is similar to the definition of façade pattern in object-oriented design pattern, it exists as the façade of the entire microservices architecture system, all external client access needs to be dispatched and filtered.

To support massive user access, Netflix has been determined to evolve from 2009 to a cloud-native microservices ecosystem, completing its overall application in 2016, migrating to the cloud with 500 + microservices, and Netflix's traffi

solve the problem mentioned above, we introduced the concept of API gateway, API Gateway is a more intelligent application server, it is similar to our micro-service architecture system façade, all external access to the API Gateway first, and then the API gateway to achieve request routing, load balancing, authorization and other functions. The spring Cloud Zuul provided in spring Cloud implements the functionality of the API gateway, so let's take

This requires the entire system to do a perfect authority control system. The system should have a pin to distinguish between users, permissions, roles and other necessary functions.
