②：新增模块启动类SpringcloudZuulServerApplication
注解@EnableZuulProxy，表示开启zuul的功能，它默认也具有@EnableCircuitBreaker和@EnableDiscoveryClient两个注解的功能
package com.haly;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.netflix.zuul.EnableZuulProxy;
@EnableZuulProxy
@SpringBootApplication
public class SpringcloudZuulServerApplication {
public static void main(String[] args) {
SpringApplication.run(SpringcloudZuulServerApplication.class, args);
}
}
③：application.properties加上以下的配置代码：
server.port=9700
spring.application.name=springcloud-zuul-server
eureka.client.serviceUrl.defaultZone=http://localhost:8761/eureka/
zuul.ignored-services: "*"
zuul.routes.a.path = /api/a/**
zuul.routes.a.serviceId = springcloud-feign-client
zuul.routes.b.path = /api/b/**
zuul.routes.b.serviceId = springcloud-feign-client
先解释下配置含义
zuul.ignored-services: "*" ： 之前我们说过可以用服务名直接访问接口，如果我们不想向外界暴露除了application.properties配置映射的服务接口，配置这个属性，只能通过zuul映射的路径访问。
zuul.routes.a.path = /api/a/**
zuul.routes.a.serviceId = springcloud-feign-client
当我们访问zuul服务模块时，只要包含 /api/a/ 路径的服务请求，默认请求到springcloud-ribbon-client模块上的接口
zuul.routes.b.path = /api/b/**
zuul.routes.b.serviceId = springcloud-feign-client
同理，当我们访问zuul服务模块时，只要包含 /api/b/ 路径的服务请求，默认请求到springcloud-feign-client模块上的接口
3. 运行项目
启动 注册中心 springcloud-eureka-server，启动springcloud-ribbon-client服务模块，启动springcloud-feign-client服务模块，启动springcloud-zuul-server模块
在这里首先我要表达歉意，在第一章搭建多模块的微服务项目时，我使用的springcloud和springboot的版本会有问题，所以本章节启动springcloud-zuul-server模块时报错，具体报错如下：
原因是springb
