新建cloud-provider-payment8004

1、pom

<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>3.4.9</version>
    </dependency>

2、yml

# 8004是zookeeper服务器的支付服务提供者端口号
    server:
      port: 8004
    spring:
      application:
        name: cloud-provider-payment
      cloud:
        zookeeper:
          connect-string: 192.168.1.10:2181 # zookeeper注册中心地址

3、主启动类

@SpringBootApplication
    @EnableDiscoveryClient //该注解用于向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);
        }
    }

### 将服务提供者cloud-providerconsul-paymen8006注册进consul ###

1、pom.xml

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-consul-discovery</artifactId>
    </dependency>

2、application.yml

## consul 服务端口号
    server:
      port: 8006
    spring:
      application:
        name: consul-provider-payment
      # consul 注册中心地址
      cloud:
        consul:
          host: localhost
          port: 8500
          discovery:
            service-name:  \${spring.application.name}
            # hostname: 127.0.0.1

3、主启动类

@SpringBootApplication
    @EnableDiscoveryClient //该注解用于向consul或者zookeeper作为注册中心时注册服务
    public class PaymentMain8006 {
        public static void main(String[] args) {
            SpringApplication.run(PaymentMain8006.class, args);
        }
    }

### 将服务消费者cloud-consumerconsul-order80注册进consul ###

1、pom.xml

<dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-consul-discovery</artifactId>
    </dependency>

2、application.yml

## consul 服务端口号
    server:
      port: 80
    spring:
      application:
        name: consul-consumer-payment
      # consul 注册中心地址
      cloud:
        consul:
          host: localhost
          port: 8500
          discovery:
            service-name:  \${spring.application.name}
            # hostname: 127.0.0.1

3、主启动类

@SpringBootApplication
    @EnableDiscoveryClient
    public class OrderConsulOrder80 {
        public static void main(String[] args) {
            SpringApplication.run(OrderConsulOrder80.class, args);
        }
    }

4、调用工具

@Configuration
    public class ApplicationContextConfig {
        @Bean
        @LoadBalanced
        public RestTemplate getRestTemplate() {
            return new RestTemplate();
        }
    }
