### 1.Consul介绍 ###

Consul是一种服务网格解决方案，提供具有服务发现，配置和分段功能的全功能控制平面。这些功能可以根据需要单独使用，也可以一起使用以构建完整的服务网格。Consul需要一个数据平面，并支持代理和本机集成模型。Consul附带了一个简单的内置代理，因此一切都可以直接使用，还支持Envoy等第三方代理集成。

@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 Payment8006 {
        public static void main(String[] args) {
            SpringApplication.run(Payment8006.class,args);
        }
