SpringCloud注册中心之Zookeeper

1.导入pom

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

        <artifactId>cloud2020</artifactId>
        <groupId>com.atguigu.springcloud</groupId>
        <version>1.0-SNAPSHOT</version>
    </parent>

        </dependency>
        <!--SpringBoot整合Zookeeper客户端-->
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
        </dependency>
        <dependency>

            <scope>test</scope>
        </dependency>
    </dependencies>

</project>
 

2.修改yml

server:
  # 8004表示注册到zookeeper服务器的支付服务提供者端口号
  port: 8004
spring:
  application:
    # 服务别名---注册zookeeper到注册中心的名称
    name: cloud-provider-payment
  cloud:
    zookeeper:
      # 默认localhost:2181
      connect-string: localhost:2181
 

3.启动zk : zkServer.sh start

4.启动后报错，注意jar冲突

5.新建一个消费者，导入pom

</project>
 

6.修改yml

server:
  port: 80
spring:
  application:
    # 服务别名
    name: cloud-consumer-order
  cloud:
    zookeeper:
      # 注册到zookeeper地址
      connect-string: localhost:2181
 

7.测试
