1、创建一个父类便于版本控制

pom:
<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>com.saas</groupId>
<artifactId>my-saas</artifactId>
<version>0.0.1-SNAPSHOT</version>
<packaging>pom</packaging>

<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.4.1.RELEASE</version>
</parent>
<modules>
<module>spring-demo-register</module>
</modules>

<dependencyManagement>
<dependencies>
<dependency>

<type>pom</type>

<build>

</build>
</project>
2、创建一个注册中心
注意是在上面基础上建一个model

pom：
<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>
<parent>
<groupId>com.saas</groupId>
<artifactId>my-saas</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>my-saas-gateway</artifactId>

<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka-server</artifactId>
</dependency>
</dependencies>
</project>
创建启动方法：

application.yml文件：

注册中心创建完成，我们启动服务试一下；
在浏览器输入：http://127.0.0.1:8090/
出现如下界面说明，注册中心创建成功

3、创建服务
创建一个model项目，与步骤2基本一致
pom：
<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>
<parent>
<groupId>com.saas</groupId>
<artifactId>my-saas</artifactId>
<version>0.0.1-SNAPSHOT</version>
</parent>
<artifactId>my-saas-admin</artifactId>
<dependencies>

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-eureka</artifactId>
</dependency>

</dependencies>
</project>
启动类：

image.png

application.yml:

server:
port: 3000

spring:
application:
name: my-saas-admin

注册中心指向start

eureka:
instance:
instance-id: my-saas-admin
appname: ${spring.application.name}
client:

注册中心

service-url: 
  defaultZone: http://127.0.0.1:8090/eureka/

服务类创建完成，我们再次启动，注册中心与服务类，

服务已注册；
