SpringBoot 2.x搭建注册中心（Eureka）

1.创建spring boot项目

 http://start.spring.io/ 自定义spring boot在线maven构建工具

2.修改pom文件，添加spring cloud 依赖

   <properties>

      <spring-cloud.version>Finchley.RELEASE</spring-cloud.version>
   </properties>

   <dependencies>
      <dependency>
         <groupId>org.springframework.boot</groupId>

      </dependency>

         <artifactId>spring-boot-starter-test</artifactId>
         <scope>test</scope>
      </dependency>

      <!-- springCloud注测中心服务 -->
      <dependency>
         <groupId>org.springframework.cloud</groupId>
         <artifactId>spring-cloud-starter-netflix-eureka-server</artifactId>
      </dependency>

   </dependencies>

   <!--spring cloud版本-->
   <dependencyManagement>
      <dependencies>
         <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>${spring-cloud.version}</version>

         </dependency>

   </dependencyManagement>

   <build>
      <plugins>
         <plugin>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-maven-plugin</artifactId>
         </plugin>
      </plugins>
   </build>

</project>

3.修改application.properties

spring.application.name=eureka-server
#注册中心端口
server.port=1000
#主机名，会在控制页面中显示
eureka.instance.hostname=localhost

#表示是否将自己注册到Eureka Server上，默认为true
eureka.client.register-with-eureka=false
#表示是否从Eureka Server上获取注册信息，默认为true
eureka.client.fetch-registry=false
#注册地址
eureka.client.serviceUrl.defaultZone=http://${eureka.instance.hostname}:${server.port}/eureka/

4.启动项目
