微服务项目框架搭建

一. 服务说明

eureka-server ------> 注册中心
member-service ------> 会员服务接口
member-service-impl ------> 会员服务实现
order-service ------> 订单服务接口
order-service-impl -------> 会员服务实现

补充说明: 之后要创建member-service,order-service两个接口服务,是为了提高代码的覆用性.具体可参见后面的代码

二.创建项目

1.整体结构

　　　2.创建springcloud-hystrix父工程

2.1 创建一个maven项目(略)

2.1 pom.xml依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<modelVersion>4.0.0</modelVersion>

<groupId>qinfeng.zheng</groupId>
<artifactId>springcloud-hystrix</artifactId>

<version>1.0-SNAPSHOT</version>

<module>eureka-server</module>

</modules>

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>

</project>

　　3.创建eureka-service子模块

　　　　3.1 创建一个maven工程

　　 3.2 pom.xml依赖

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
<parent>
<artifactId>springcloud-hystrix</artifactId>
<groupId>qinfeng.zheng</groupId>
<version>1.0-SNAPSHOT</version>
</parent>
<modelVersion>4.0.0</modelVersion>

<artifactId>eureka-server</artifactId>
<dependencies>

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
</dependency>
</dependencies>
</project>

　　　　3.3 在resources目录下创建application.yml文件

###服务端口号
server:
  port: 8888
##定义服务名称
spring:
 application:
 name: eureka-server
eureka:
 instance:
 ###注册中心ip地址
 hostname: 127.0.0.1
 client:
 serviceUrl:
 ##注册地址
 defaultZone: http://${eureka.instance.hostname}:8888/eureka/
 ####因为自己是注册中心，是否需要将自己注册给自己的注册中心（集群的时候是需要是为true）
 register-with-eureka: false
 ###因为自己是注册中心， 不需要去检索服务信息
 fetch-registry: false
 server:
 # 测试时关闭自我保护机制，保证不可用服务及时踢出,,,若要及时踢出过期服务,还需要在客户端进行配置
 enable-self-preservation: false
 eviction-interval-timer-in-ms: 2000
