一、注册中心Zookeeper

二、服务提供者

三、服务消费者

--------------------

## 一、注册中心Zookeeper ##

zookeeper是一个分布式协调工具，可以实现注册中心功能

关闭Linux服务器防火墙后启动zookeeper服务器

zookeeper服务器取代Eureka服务器，zk作为服务注册中心

[Linux环境下安装Zookeeper3.5.7\_zoeil的博客-CSDN博客][Linux_Zookeeper3.5.7_zoeil_-CSDN]

## 二、服务提供者 ##

### （一）新建cloud-provider-payment8004 ###

### （二）POM ###

<dependencies>
            
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-web</artifactId>
            </dependency>
            <dependency>
                <groupId>com.atguigu.springcloud</groupId>
                <artifactId>cloud-api-commons</artifactId>
                <version>${project.version}</version>
            </dependency>
            
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-starter-zookeeper-discovery</artifactId>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-devtools</artifactId>
                <scope>runtime</scope>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>org.projectlombok</groupId>
                <artifactId>lombok</artifactId>
                <optional>true</optional>
            </dependency>
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-starter-test</artifactId>
                <scope>test</scope>
            </dependency>
        </dependencies>

### （三）YML ###

#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

### （四）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);
        }
    
    }

### （五）Controller ###

@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();
        }
    }

### （六）启动8004注册进zookeeper ###

**启动后报错**

### （八）验证测试2 ###

### （九）思考 ###

服务节点是临时节点还是持久节点，我们将cloud-provider-payment关闭之后，节点消失了，当我们重新启动cloud-provider-payment后，节点恢复但不是同一个流水号了，因此是临时节点

## 三、服务消费者 ##

### （一）新建cloud-consumerzk-order80 ###

### （二）POM ###

            </dependency>
        </dependencies>

### （三）YML ###

server:
      port: 80
    
    spring:
      application:
        name: cloud-consumer-order
      cloud:
      #注册到zookeeper地址
        zookeeper:
          connect-string: 192.168.111.144:2181

### （四）主启动类 ###

@Configuration
    public class ApplicationContextBean
    {
        @Bean

        public RestTemplate getRestTemplate()
        {
            return new RestTemplate();
        }
    }

### （五）配置Bean和Controller ###

@SpringBootApplication
    public class OrderZK80
    {
        public static void main(String[] args)
        {
            SpringApplication.run(OrderZK80.class,args);
        }
    }

cotroller

@RestController
    public class OrderZKController
    {
        public static final String INVOKE_URL = "http://cloud-provider-payment";
    
        @Autowired
        private RestTemplate restTemplate;
    
        @RequestMapping(value = "/consumer/payment/zk")
        public String paymentInfo()
        {
            String result = restTemplate.getForObject(INVOKE_URL+"/payment/zk", String.class);
            System.out.println("消费者调用支付服务(zookeeper)--->result:" + result);
            return result;
        }
    
    }
