spring cloud_zuul

注册路由时报错：

路由Forwarding error错误

原因：

配置文件通过微服务id找不到微服务：

zuul:

  routes:
    #路由转发
    api-basicS:
      path: /api-basicS/**
      serverId: basic_servic

修改为：

zuul:

  routes:
    #路由转发
    api-basicS:
      path: /api-basicS/**
      url: http://localhost:8763

虽然不报错能正常使用
但是扔没解决如何通过serverId找到服务，希望大神指点。

这里列出zuul的gradle配置:（可能有部分是多余的）

dependencies {
    compile('org.springframework.cloud:spring-cloud-config-server')
    compile('org.springframework.cloud:spring-cloud-starter-eureka')
    compile('org.springframework.boot:spring-boot-starter-web')
    compile('org.springframework.cloud:spring-cloud-starter-netflix-ribbon')
    compile('org.springframework.cloud:spring-cloud-starter-netflix-zuul')
    compile('org.springframework.cloud:spring-cloud-starter-hystrix')
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

以下是basic_servic服务的配置：

eureka:
  client:
    serviceUrl:
      defaultZone: http://localhost:8761/eureka/
server:
  port: 8763
spring:
  application:
    name: basic_servic

    }
