# spring-cloud-demo 

#### 介绍
spring-cloud-demo用于学习springcloud框架演示应用。

####  Eureka教程
1.  搭建eureka-server步骤  

1.1  引入依赖 
```xml
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
```  
1.2  配置yml文件
```yaml
spring:
  application:
    name: eureka-server
server:
  port: 8761
eureka:
  instance:
    hostname: localhost
  client:
    register-with-eureka: false
    fetch-registry: false
    service-url:
      defaultZone: http://${eureka.instance.hostname}:${server.port}/eureka/
```
1.3 配置启动类
```java
@SpringBootApplication
@EnableEurekaServer
public class EurekaApplication {
    public static void main(String[] args) {
        SpringApplication.run(EurekaApplication.class,args);
    }
}

```
2.  搭建Eureka-Client 步骤  

2.1  引入依赖
```xml
<dependency>
    <groupId>org.springframework.cloud</groupId>
    <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId>
</dependency>
```
2.2  配置yml文件  
```yaml
eureka:
  client:
    service-url:
      defaultZone: http://localhost:8761/eureka
  instance:
    prefer-ip-address: true
    instance-id: ${spring.cloud.client.ip-address}:${server.port}
    lease-renewal-interval-in-seconds: 5 #向注册中心注册服务的心跳间隔时间
    lease-expiration-duration-in-seconds: 10 #续约到期时间
```
2.3 配置启动类
```java
/**
 *
 * @author ZhangHua
 *
 * * @EnableDiscoveryClient == @EnableEurekaClient 注解作用一样，可以不用写
 */
//@EnableEurekaClient
//@EnableDiscoveryClient
@SpringBootApplication
public class GoodsApplication {
    public static void main(String[] args) {
        SpringApplication.run(GoodsApplication.class, args);
    }
}

```

3.  Eureka高可用集群
   Eureka 相互注册即可
