Some of summary springcloud

@EnnableEurekaServer

spring:
  application:
    name: spring-cloud-eureka
  profiles: peer1
server:
  port: 8000
eureka:
  instance:
    hostname: peer1
  client:
    serviceUrl:
      defaultZone: http://peer2:8001/eureka/,http://peer3:8002/eureka/

Such a critical registry services, general production can not be the one, then it registered another two, three, then, between two mutually registered.
= eureka.client.serviceUrl.defaultZone HTTP: // xxxx: 8000 / Eureka /, HTTP: // xxxx: 8001 / Eureka /
Eureka clusters, each registration.

@EnnableDiscoveryClient
@EnnableFeignCLients

@FeignClient(name= "spring-cloud-producer")
public interface HelloRemote {
    @RequestMapping(value = "/hello")
    public String hello(@RequestParam(value = "name") String name);
}

feign.hystrix.enabled=true

@FeignClient(name= "spring-cloud-producer",fallback = HelloRemoteHystrix.class)
public interface HelloRemote {

    @RequestMapping(value = "/hello")
    public String hello(@RequestParam(value = "name") String name);
}

Avalanche effect: a service provider can not lead consumers to table service is not available and can not be gradually enlarged process.
CircuitBreaker
Hystrix

After SpringCloud 2.0 hystrix.stream 404 to solve the problem, to add in the application.properties:
management.endpoints.web.exposure.include = hystrix.stream
management.endpoints.web.base-path = /

@EnableConfigServer

The number of requests for the plurality of API call logic-polymerization, thereby reducing the client

@EnableZuulProxy

#这里的配置表示，访问/it/** 直接重定向到http://www.xxxx.com/**
