注册中心 Zookeeper

1.pom引入依赖

<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
    <exclusions>
        <exclusion>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
        </exclusion>
    </exclusions>
</dependency>

2.修改yml配置

spring:
  application:
    name: cloud-order-service
  cloud:
    zookeeper:
      connect-string: localhost:2181

3.主启动类上添加 @EnableDiscoveryClient

@SpringBootApplication
@EnableDiscoveryClient
public class OrderZkMain80 {
    public static void main(String[] args) {
        SpringApplication.run(OrderZkMain80.class, args);
    }
}

4.依赖冲突问题

注意 spring-cloud-starter-zookeeper-discovery包中包含 org.apache.zookeeper.discovery，可能会版本冲突，使用exclusions标签进行排除
