服務(wù)注冊

1.添加Spring Cloud Zookeeper依賴:

<dependencies><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><dependency><groupId>org.apache.zookeeper</groupId><artifactId>zookeeper</artifactId><version>3.6.2</version><exclusions><exclusion><groupId>org.slf4j</groupId><artifactId>slf4j-log4j12</artifactId></exclusion></exclusions></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId></dependency></dependencies>

2.在服務(wù)配置文件中添加zookeeper配置:

spring: cloud: zookeeper: connect-string: localhost:2181 #zookeeper地址

3.啟動zookeeper服務(wù)器和服務(wù)（我這邊是啟動了兩個服務(wù)，分別是provider和consumer），然后在zookeeper客戶端中可以查看已經(jīng)注冊到zookeeper中的服務(wù):

服務(wù)發(fā)現(xiàn)

1.創(chuàng)建controller

消費(fèi)者controller:

package com.buhe.zk.controller;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.cloud.client.ServiceInstance;import org.springframework.cloud.client.discovery.DiscoveryClient;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RestController;import org.springframework.web.client.RestTemplate;import java.util.List;@RestControllerpublic class ZkConsumerController { private static final String SERVICE_NAME = 'provider'; private static final String SERVICE_PATH = '/zk/provider'; @Autowired private RestTemplate restTemplate; @Autowired private DiscoveryClient discoveryClient; /** * 調(diào)用提供者服務(wù) * @return */ @GetMapping('/zk/consumer') public String zkConsumer(){ return '我吃了' + restTemplate.getForObject('http://' + SERVICE_NAME + SERVICE_PATH, String.class); } /** * 獲取提供者服務(wù)URL * @return */ @GetMapping('/zk/url') public String serviceUrl() { List<ServiceInstance> list = discoveryClient.getInstances(SERVICE_NAME); if (list != null && list.size() > 0 ) { return list.get(0).getUri().toString() + SERVICE_PATH; } return null; }}

要使用RestTemplate別忘了加配置：

@Bean@LoadBalancedpublic RestTemplate restTemplate(){return new RestTemplate();}

提供者controller:

package com.buhe.zk.controller;import org.springframework.web.bind.annotation.GetMapping;import org.springframework.web.bind.annotation.RestController;@RestControllerpublic class ZkProviderController { @GetMapping('/zk/provider') public String zkProvider(){ return '10個蘋果'; }}

2.服務(wù)調(diào)用

以上就是基于Spring Cloud Zookeeper實(shí)現(xiàn)服務(wù)注冊與發(fā)現(xiàn)的詳細(xì)內(nèi)容，更多關(guān)于Spring Cloud Zookeeper服務(wù)注冊與發(fā)現(xiàn)的資料請關(guān)注好吧啦網(wǎng)其它相關(guān)文章！
