微服务虽然可以将我们的开发单元拆分的更为细致，有效降低了开发难度，但是他所引出的各种问题如果处理不当会成为实施过程中的不稳定因素。甚至掩盖掉原本实施微服务带来的优势。所以再微服务的实施方案中，api网关服务的使用几乎成为了必要的选择。

下面着手搭建一个可用的api-gateway服务

构建springcloud-server-api-gateway服务

引入依赖

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.9.RELEASE</version>
    <relativePath />

        <groupId>org.springframework.boot</groupId>

</dependencies>

创建入口文件

@SpringCloudApplication
@EnableZuulProxy
public class SpringCloudServerApiGatewayApplication {
    public static void main(String[] args) {
        SpringApplication.run(SpringCloudServerApiGatewayApplication.class,args);
    }
}

创建配置文件

  port: 8004
spring:
  application:
    name: springcloud-server-api-gateway
eureka:
  client:
    service-url:
      defaultZone: http://peer1:8080/eureka/

zuul:
  routes:
    api-a:
      path: /api-a/**
      serviceId: springcloud-consumer-ribbon
    api-b:
      path: /api-b/**
      serviceId: springcloud-consumer-feign
