你好,这里是codetrend专栏“SpringCloud2023实战”。欢迎点击关注查看往期文章。
注册中心在前文提到有很多选型,在这里以Spring Cloud Zookeeper为例说明注册中心的集成和使用。
选择Spring Cloud Zookeeper作为注册中心原因如下:
io.rainforest
banana

package io.rainforest.banana.client1;

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}
}
spring.application.name: client1

zookeeper:
connect-string: localhost:2181 ## 注册中心的配置
server:
port: 10101
servlet:
context-path: /client1
get /services/client1/b257e7f5-a451-4119-ba20-e7622f3aeaba
{"name":"client1","id":"b257e7f5-a451-4119-ba20-e7622f3aeaba","address":"cat","port":10101,"sslPort":null,"payload":{"@class":"org.springframework.cloud.zookeeper.discovery.ZookeeperInstance","id":"client1","name":"client1","metadata":{"instance_status":"UP"}},"registrationTimeUTC":1698715221404,"serviceType":"DYNAMIC","uriSpec":{"parts":[{"value":"scheme","variable":true},{"value":"://","variable":false},{"value":"address","variable":true},{"value":":","variable":false},{"value":"port","variable":true}]}}
默认的zookeeper注册中心的数据放在 /services/客户端名称/实例名称
。
