36.  
    #设置的id是dubbo-starter-reference
37.  
    - id: reference
38.  
    #网关不设置上下问,服务存在上下问情况
39.  
    #找不到lb实例，这种写法管用的 http://dubbo-starter-reference:9997,-Path设置为 - Path=/dubbo-reference/**
40.  
    uri: lb://dubbo-starter-reference
41.  
    predicates:
42.  
    - Path=/reference/**
43.  
    filters:
44.  
    ##由于微服务dubbo-starter-reference中设置了server.servlet.context-path=/dubbo-starter-reference，要重写路径才能正常路由到该微服务
45.  
    - RewritePath=/reference/?(?<segment>.*), /dubbo-starter-reference/$\{segment}
46.  
    management:
47.  
    endpoint:
48.  
    gateway:
49.  
    #默认是true
50.  
    enabled: true
51.  
    endpoints:
52.  
    web:
53.  
    exposure:
54.  
    #一直存在的
55.  
    include: "*"
56.  
    hystrix:

    default:

    execution:

    strategy: SEMAPHORE
62.  
    thread:
63.  
    timeoutInMilliseconds: 3000
64.  
    shareSecurityContext: true

上面是网关的简单配置，使用http://dubbo-starter-reference:9997可以访问成功

进入gateway的pod容器，连接dubbo-starter-reference实例正常，

将uri: lb://dubbo-starter-reference，访问接口出现404的错误。

描述：pom.xml描述，配置了actuator，并且application.yaml中设置
