7.Zookeeper服务注册与发现
- 新建cloud-provider-payment8004
- 修改pom文件，加上以下依赖
<dependencies>
<!-- SpringBoot整合Web组件 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency><!-- 引入自己定义的api通用包，可以使用Payment支付Entity -->
<groupId>com.zhubayi.springcloud</groupId>
<artifactId>cloud-api-commons</artifactId>
<version>${project.version}</version>
</dependency>
<!-- SpringBoot整合zookeeper客户端 -->
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
<!--先排除自带的zookeeper3.5.3-->
<exclusions>
<exclusion>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
</exclusion>
</exclusions>
</dependency>
<!--添加zookeeper3.7.0版本-->
<dependency>
<groupId>org.apache.zookeeper</groupId>
<artifactId>zookeeper</artifactId>
<version>3.7.0</version>
</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>

</dependency>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-test</artifactId>
<scope>test</scope>
</dependency>
</dependencies>- 修改配置文件
#8004表示注册到zookeeper服务器的支付服务提供者端口号
server:
port: 8004
#服务别名----注册zookeeper到注册中心名称
spring:
application:
name: cloud-provider-payment
cloud:
zookeeper:
connect-string: 192.168.111.144:2181主启动类PaymentMain8004
package com.zhubayi.springcloud;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
/**
* @author zhubayi
*/
@SpringBootApplication
@EnableDiscoveryClient
public class PaymentMain8004 {
public static void main(String[] args) {
SpringApplication.run(PaymentMain8004.class,args);
}
}controller
package com.atguigu.springcloud.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.beans.factory.annotation.Value;
import java.util.UUID;
@RestController
public class PaymentController
{
@Value("${server.port}")
private String serverPort;
@RequestMapping(value = "/payment/zk")
public String paymentzk()
{
return "springcloud with zookeeper: "+serverPort+"\t"+ UUID.randomUUID().toString();
}
}.启动8004注册进zookeeper
去zookeeper客户端查看
- 可以看到8004端口注册了进来。
- 完整的目录结构
查看节点的信息
格式化后
{
"name": "cloud-provider-payment",
"id": "afbf8a81-9e2c-430f-b616-d0b840c7a665",
"address": "zhubayi-computer",
"port": 8004,
"sslPort": null,
"payload": {
"@class": "org.springframework.cloud.zookeeper.discovery.ZookeeperInstance",
"id": "application-1",
"name": "cloud-provider-payment",
"metadata": { }
},
"registrationTimeUTC": 1625677007132,
"serviceType": "DYNAMIC",
"uriSpec": {
"parts": [
{
"value": "scheme",
"variable": true
},
{
"value": "://",
"variable": false
},
{
"value": "address",
"variable": true
},
{
"value": ":",
"variable": false
},
{
"value": "port",
"variable": true
}
]
}
}然后去创建服务消费者
- 新建cloud-consumerzk-order80
- 修改pom文件添加以下的依赖。
<dependencies>
<!-- SpringBoot整合Web组件 -->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency><!-- 引入自己定义的api通用包，可以使用Payment支付Entity -->

<version>${project.version}</version>
</dependency>
<!-- SpringBoot整合zookeeper客户端 -->

<dependency>

</dependency>
</dependencies>- 修改配置文件
server:
port: 80
spring:
application:
name: cloud-consumer-order
cloud:
#注册到zookeeper地址
zookeeper:
connect-string: 127.0.0.1:2181- 主启动类OrderZKMain80
package com.zhubayi.springcloud;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class OrderZKMain80 {
public static void main(String[] args) {
SpringApplication.run(OrderZKMain80.class,args);
}
}
- 业务类，向容器注入bean
- config
package com.zhubayi.springcloud.config;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.client.RestTemplate;
@Configuration
public class ApplicationContextConfig {
@Bean
@LoadBalanced //开启负载均衡
public RestTemplate restTemplate(){
return new RestTemplate();
}
}- controller层
package com.zhubayi.springcloud.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
public class OrderZkController {
public static final String URL="http://cloud-provider-payment";
@Autowired
private RestTemplate restTemplate;
@GetMapping("consumer/payment/zk")
public String paymentInfo(){
return restTemplate.getForObject(URL+"/payment/zk",String.class);
}
}完整文件目录结构
启动80端口，然后去zookeeper客户端查看
可以看到两个服务成功的注册了进来。
