Zuul是什么？
Zuul包含了对请求的路由和过滤两个最主要的功能:
其中路由功能负责将外部请求转发到具体的微服务实例上，是实现外部访问统一 入口的基础而过滤器功能则负责对请求的处理过程进行干预，是实现请求校验、服务聚合等功能的基础。
Zuul和Eureka进行整合，将Zuul自身注册为Eureka服务治理下的应用，同时从Eureka中获得其他微服务的消息，也即以后的访问微服务都是通过Zuul跳转后获得。
Zuul服务最终还是会注册进Eureka
创建一个微服务microservicecloud-zuul-gateway-9527

yml配置：
server: port: 9527 spring: application: name: microservicecloud-zuul-gateway eureka: client: service-url: defaultZone: http://eureka7001:7001/eureka/,http://eureka7003:7003/eureka/ instance: instance-id: gateway-9527.com prefer-ip-address: true
启动类添加@EnableZuulProxy注解
@SpringBootApplication @EnableZuulProxy public class Zuul_9527_StartSpringCloudApp { public static void main(String[] args) { SpringApplication.run(Zuul_9527_StartSpringCloudApp.class, args); } }
启动7001与8001端口的微服务,就可以通过路由的Zuul去访问8001的接口了
http://myzuul.com:9527/microservicecloud-dept/dept/get/1
Zuul的域名+端口+8001微服务的名称+接口就可以访问了
如果我们要隐藏8001的服务名称可以在9527的yml中添加配置
zuul: #ignored-services: microservicecloud-dept //忽略 prefix: /bushro //添加公共的前缀 ignored-services: "*" //隐藏所有微服务的名称 routes: mydept.serviceId: microservicecloud-dept //把当前的服务名称隐藏变成下面的 mydept.path: /mydept/**
