In the micro-service architecture, several basic micro-services are required, including service registration and discovery, service consumption, load balancing, circuit breakers, I-can routing, configuration management, and so on, by these several basic components to work together to build a simple micro-service system.-zuul IntroductionZuul is Netflix's open source MicroServices gateway, which he can use with components such as Eureka,ribbon,hystrix.

this article to understand: Configuration Center and message busService GatewayIn MicroServices architecture mode, the number of instances of back-end services is generally dynamic, and it is difficult for clients to discover the access address information of dynamically changing service instances. Therefore, in order to simplify the invocation logic of the front end in a microservices-based project, the API gateway is often introduced as a lightweight gateway, and the API gateway implements th

Springcloud Consolidated PHP, python examples Code has been uploaded to: https://github.com/KeoZmy/SpringCloudDemo.git, the blog did not write to the gateway Zuul, but Git has uploaded the preface Recently spent time studying micro services, various open source components combine a framework to the final decision to use springcloud such a mature framework. Have to say, Springcloud is indeed very strong, there are pivotal and Netfix is its strong back

At the same time, by completing the checksum filtering in the gateway, the micro-service application can remove all kinds of complex filters and interceptors, which makes the interface development and testing complexity of the micro-service application be reduced correspondingly.To enable validation of client requests in the API gateway, we will need to use another core feature of spring Cloud Zuul: Filters.Zuul allows developer

changed the retry of Feignfeign.Retryer#NEVER_RETRYTo use Feign retry, you only need to use Ribbon retry configuration. Therefore, for Camden and later versions, you can use the following attributes to configure Feign retry: ribbon: MaxAutoRetries: 1 MaxAutoRetriesNextServer: 2 OkToRetryOnAllOperations: false Refer to: https://github.com/spring-cloud/spring-cloud-netflix/issues/467 for related Issue Zuul retry Configuration:

Background:I'm going to do the system before placing Zuul. Use the single sign-on service provided by your company. The subsequent business application is also the rest service supported by spring BOOT.After the user request is scheduled to come up. Single Sign-on is implemented in Zuul with a custom filter. The user's information, including accounts and privileges, is deposited into session.The spring sess
