zookeeper作注册中心 - 服务提供者代码

1.zookeeper准备:

关闭防火墙：systemctl stop firewalld

zookeeper安装地址：

 

 ping通本机：

 

 

2.建工程cloud-provider-payment8004

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"

    </parent>
    <modelVersion>4.0.0</modelVersion>

    <artifactId>cloud-provider-payment8004</artifactId>

    <dependencies>

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

yml:

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: 192.168.53.179:2181

主启动类：

@SpringBootApplication
@EnableDiscoveryClient  //该注解用于向使用consul或者zookeeper作为注册中心时注册服务
public class PaymentMain8004 {
    public static void main(String[] args) {
        SpringApplication.run(PaymentMain8004.class, args);
    }
}

controller:

@RestController
@Slf4j
public class PaymentController {
    @Value("${server.port}")
    private String port;

    @RequestMapping(value = "/payment/zk")
    public String paymentZookeeper() {
        return "cloud with zookeeper" + port + "\t" + UUID.randomUUID().toString();
    }
}

 

 

3.测试注册进zookeeper

zookeeper打开客户端：

 查看根节点：

启动工程后，多了一个service:

 看看这个service:

 查看在zookeeper的基本信息：

 

 

 

4.测试程序访问成功
