新建springboot项目，pom文件如下：

    			</plugin>
    		</plugins>
    	</build>
    
    	
    
    </project>

resource下yml文件：

server:
      port: 8010
    spring:
      application:
        name: test-zuul
      cloud:
        consul:
          host: localhost
          port: 8500
          discovery:
            serviceName: ${spring.application.name} # 注册到consul的服务名称
    zuul:
      routes:
        admin:
          path: /admin/**
          serviceId: test-admin  # 转发到消费者 / test-admin/

这个路由转发可以自定义：如本来有个系统管理的微服务，端口为8001，有个登录的接口，localhost:8001/login，通过路由转发之后（zuul设置的端口为8010）请求的地址可为：localhost:8010/admin/login，便于统一管理。当然不设置转发也可这样：localhost:8010/$\{spring.application.name\}/url,如登录地址：localhost:8010/test-admin/login

启动类：

@EnableZuulProxy
    @EnableDiscoveryClient
    @SpringBootApplication(scanBasePackages={"com.test.ream"})
    public class TestZuulApplication {
    
    	public static void main(String[] args) {
    		SpringApplication.run(TestZuulApplication.class, args);
    	}
    
    }

@EnableZuulProxy：启动网关

@EnableDiscoveryClient：启用服务发现（注册到consul）

@SpringBootApplication：启动类必备。。。

告辞
