【Spring Cloud】--SpringCloud的服务注册与发现【Eureka】

spring cloud 提供了类似于zookeeper的服务注册中与管理中心Eureka。
spring cloud的服务与注册中心与其他的注册中心结构类似：
1，注册中心：
不同于zookeeper的安装形式，spring cloud 的注册中心需要写一个单独的工程来实现：
项目结构：
实现注册中心只需要三个文件即可：
RegApplication.java
application.properties
pom.xml
首先引入需要的包：
RegApplication.java
注册中心配置：application.properties
验证：访问http://localhost:1111/ 出现Eureka配置中心界面【看见你就知道】
服务提供者：
服务的提供者需要四个文件，项目结构如下：
引入包的pom.xml
HelloController.java
ServerApplication.java
配置application.properties
验证：访问：http://localhost:8080/hello 返回 Hello World Server!
服务的消费者：
项目结构：
服务的消费者同样需要四个文件即可：
引入包：pom.xml
ConsumerController.java
ConsumerApplication
注册中心配置： application.properties
