### 2.配置yml文件 ###

server:
      port: 8004
    
    spring:
      application:
        name: payment-service
      cloud:
        zookeeper:
          connect-string: 192.168.71.128:2181
    
      datasource:
        type: com.alibaba.druid.pool.DruidDataSource
        driver-class-name: com.mysql.cj.jdbc.Driver
        url: jdbc:mysql://localhost:3306/cloud_demo_01?useUnicode=true&characterEncoding=utf-8&useSSL=false&serverTimezone=UTC
        username: root
        password: 123456
    
    mybatis:
      mapper-locations: classpath:mapper/*.xml
      type-aliases-package: com.ak.demo.entities
    
    logging:

      type-aliases-package: com.ak.demo.entities
    
    logging:
      level:
        com.ak.demo.dao: debug

### 3.主启动类 ###

@EnableDiscoveryClient //该注解用于向使用consul或者zookeeper作为注册中心时注册服务
    @SpringBootApplication
    public class Payment8004 {
        public static void main(String[] args) {
            SpringApplication.run(Payment8004.class,args);
        }
    }

### 4.测试验证 ###

docker exec -it 4a2dd48ad045 /bin/bash
    
    ./zkCli.sh
    
    
    ls /services/payment-service
