1. Discovering the services that call the registry requires a consumer with a relative service, first creating a MAVEN project locally, introducing the POM, and the consumer submitting the service to the registry. To send a message as an example

1 What is Eureka?Eureka is a sub-module of Netflix that only needs to use the service's designator to access the service without modifying the configuration file of the service invocation. Functions similar to Dubbo's registry, such as zookeeper.Eureka adopts the CS design architecture, server-side Supervisor Service registration and discovery, the client terminal will be registered on the server side, afte

On the spring cloud Registry and the client registration, so this article is about how services and services are calledNot set up a small partner please refer to my previous blog: Idea Quick build Spring cloud-Registration Center and RegistrationBased on the previous article I built a client-side microservices service:So now there are two microservices, and what we're implementing is a call between MicroServices 1 and MicroServices 2The registry will not have to say, specific look at the two mic
We build the following for the Eureka project of Honghu Cloud, the whole construction process is simple, I will record every step of the construction process, I hope to help everyone:
Create a Maven project named Particle-common-eureka, which inherits the Particle-commonservice, and the specific pom.xml configuration file is as follows:

With the above introduction, we already have service registries and service providersLet's try to build a service consumerIt needs to complete two functions, discover services and consumer services, where discovery services are done by Eureka clients, and consumer services are done by the ribbon.Based on the discovery of Eureka Service, the Ribbon realizes a set of selection strategies for service instances
produced too strong feelings, we have invested time, of course, the heart wants to be able to use these tools, so it is easy to forget the application of the premise, pleasantly no matter 3,721 on the Golden Sledgehammer to show their own bad. But if we change our attitude and just see it as another tool in our toolkit, we can objectively assess it and use it as it is-always remember what the problem is. Why is always before how.There is another sentence that corresponds to the above (which I a
Spring Cloud Feign is a set of declarative service invocation clients based on the Netflix feign implementation. It makes writing Web service clients easier. We only need to configure it by creating an interface and using annotations to complete the binding to the Web service interface. It features pluggable annotation support, including feign annotations, Jax-rs annotations. It also supports pluggable encoders and decoders. Spring Cloud Feign also extends support for spring MVC annotations, whi

Service registration:In the service governance framework, a registry is typically built, and each service unit registers its own services with the registry, informing the registry of additional information such as host and port numbers, version numbers, communication protocols, and so on.The registry organizes the list of services by service name, and the registry also monitors the availability of services in the list in the form of heartbeat detection, removing them from the service if they are

Service discovery: (Eureka)
As mentioned earlier, the Eureka is divided into service-side and client-side, the server is a service registry, and the client is a service provider.
Create a service registry (service side)
First, add the following dependencies to the Pom file:
