connect-string doesn't work in application.yml

Hello , I have met a problem about the application.yml when I was building a service discovery with spring-cloud-zookeeper.

pom

application.yml

server:
  port: 8002
spring:
  application:
    name: consumer
  cloud:
    zookeeper:
      connect-string: localhost:2222
      enabled: false

exception

the app connect to localhost:2181,but not localhost:2222.It will work If I change the yml file's name from application.yml to bootstrap.yml .I guess the zk client start time is earlier than the application.yml be read. So do I have to add a bootstart.yml to my project?

Well,I found a phenomenon . If I use

<dependency>
    <groupId>org.springframework.cloud</groupId>
   <! -- <artifactId>spring-cloud-starter-zookeeper-all</artifactId> -- >
    <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
</dependency>

in my pom,the application.yml will work.I know the reason of my problem. spring-cloud-starter-zookeeper-all will introduce the zk config, zk config must use bootstrap.yml. Is it right?

That is correct
