API Gateway is a very important part of the microservices architecture, there are many different services provided to external use, API gateway can be a unified portal, can also be done on the gateway for protocol conversion, permission control and request statistics and limit flow and other workSpring-cloud encapsulates the open source API gateway implemented by Netflix Zuul, and we can easily launch an in

To track how the Eureka-consumer service is consuming the interface of the Eureka-client service /dc .From now on, I will record the process and the essence of the recently developed Springcloud micro-

Create a basic spring boot project, named Eureka-server, and introduce the required dependencies in the Pom.xml:Start a service registry with @enableeurekaserver annotations to provide conversations to other apps. This step is very simple, just add this annotation to a normal spring boot application to enable this feature, such as the following example:@EnableEurekaServer@SpringBootApplicationpublic class Application {public static void main(String[] args) {new SpringApplicationBuilder(Applicati

see the following page, where no services have been found.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 scholars. Let's explore how the Spring cloud architecture is built and
