Spring Cloud Netflix

Unresolved directive in <stdin> - include::_attributes.adoc[]

Spring Cloud Netflix provides Netflix OSS integrations for Spring Boot apps through autoconfiguration and binding to the Spring Environment and other Spring programming model idioms. With a few simple annotations you can quickly enable and configure the common patterns inside your application and build large distributed systems with battle-tested Netflix components. The patterns provided include Service Discovery (Eureka), Circuit Breaker (Hystrix), Intelligent Routing (Zuul) and Client Side Load Balancing (Ribbon)..

Features

Spring Cloud Netflix features:

Service Discovery: Eureka instances can be registered and clients can discover the instances using Spring-managed beans
Service Discovery: an embedded Eureka server can be created with declarative Java configuration
Circuit Breaker: Hystrix clients can be built with a simple annotation-driven method decorator
Circuit Breaker: embedded Hystrix dashboard with declarative Java configuration
Declarative REST Client: Feign creates a dynamic implementation of an interface decorated with JAX-RS or Spring MVC annotations
Client Side Load Balancer: Ribbon
External Configuration: a bridge from the Spring Environment to Archaius (enables native configuration of Netflix components using Spring Boot conventions)
Router and Filter: automatic registration of Zuul filters, and a simple convention over configuration approach to reverse proxy creation

Getting Started

As long as Spring Cloud Netflix and Eureka Core are on the classpath any Spring Boot application with @EnableEurekaClient will try to contact a Eureka server on http://localhost:8761 (the default value of eureka.client.serviceUrl.defaultZone):

@SpringBootApplication
@EnableEurekaClient
@RestController
public class Application {

  @RequestMapping("/")
  public String home() {
    return "Hello World";
  }

  public static void main(String[] args) {
    SpringApplication.run(Application.class, args);
  }

}

To run your own server use the spring-cloud-starter-netflix-eureka-server dependency and @EnableEurekaServer.
