SpringCloud的负载均衡组件用的是Ribbon，这个东西就是服务消费者。它只是一个配置用的中转器，放在 Zuul 和 Eureka Client 之间用来转发的，它里面写了好多规则，用来指定负载的规则。

首先，Zuul：

application.yml

eureka:

  client:

    serviceUrl:

      defaultZone: http://localhost:7087/eureka/

server:

  port:

spring:

  application:

    name: service-zuul

zuul:

  host:

    maxTotalConnections:

    maxPerRouteConnections:

  routes:

    api-a:

      path: /dbmeta/**

      serviceId: service-ribbon

    api-b:

      path: /kylin/**

      serviceId: service-kylin

ribbon:

  eureka:

    enabled: false

service-ribbon:

  ribbon:

    listOfServers: http://localhost:7088,http://localhost:7091

    ConnectTimeout: 10000

    ReadTimeout: 30000

    MaxTotalHttpConnections: 10000

    MaxConnectionsPerHost: 60000

Application

package com.shinho;

客户端就和其它的一样了，注意客户端的Service-id不要和Ribbon的重复，Ribbon的Service-id是要单独的哦。
