创建一个maven工程,打开pom文件引入依赖

 <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.0.1.RELEASE</version>
    </parent>
    <!-- 管理依赖 -->
    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Finchley.M7</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>
    <dependencies>
        <!-- zuul网关-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-zuul</artifactId>
        </dependency>
        <!-- SpringBoot整合eureka客户端 -->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
        </dependency>
    </dependencies>
    <!-- 注意： 这里必须要添加， 否者各种依赖有问题 -->
    <repositories>
        <repository>
            <id>spring-milestones</id>
            <name>Spring Milestones</name>
            <url>https://repo.spring.io/libs-milestone</url>
            <snapshots>
                <enabled>false</enabled>
            </snapshots>
        </repository>
    </repositories>

创建application.yml文件

###注册中心
eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8100/eureka/
server:
  port: 80
###网关名称
spring:
  application:
    name: service-zuul
### 配置网关反向代理
zuul:
  routes:
    api-a:
      ### 客户端法师请求127.0.0.1:80/api-mabber开头的,都转发到会员服务
      path: /api-member/**
      ###服务别名 zuul网关默认整合ribbon 自动实现本地负载均衡轮循环效果
      serviceId: app-songzixian-member
    api-b:
      ### 客户端法师请求127.0.0.1:80/api-order开头的,都转发到订单服务
      path: /api-order/**
      serviceId: app-songzixian-order

启动测试

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