SpringCloud之Eureka详细的配置
本文内容纲要：
-介绍
-术语和概念
-配置说明
-Eureka服务器配置
-EurekaInstacen配置
-Eureka客户端配置
介绍
SpringCloud是一个完整的微服务治理框架，包括服务发现和注册，服务网关，熔断，限流，负载均衡和链路跟踪等组件。
SpringCloud-Eureka主要提供服务注册和发现功能。本文提供了该组件配置的全面说明。
术语和概念
- Eureka服务端：负责服务注册、发现并管理每项服务的中心
- **Eureka实例：**服务（如订单系统）部署多个服务器，每个服务器上提供的服务都是实例。
- Eureka服务：指提供特定服务功能的服务，例如：订单系统，同一服务可以提供多个实例;
- Eureka客户端：主要向服务中心注册自己成为服务。但它既可以是服务提供者，也可以是消费者。它与Eureka实例感觉相似，但实际上意义不同。
配置说明
