@EnableEurekaServer注解不可用

1.可能是springBoot版本和spingCloud版本不匹配

parent pom做了如下修改

<!--基于springboot开发-->
<parent>
  <groupId>org.springframework.boot</groupId>
  <artifactId>spring-boot-starter-parent</artifactId>
  <version>1.5.6.RELEASE</version>
  <relativePath/>
</parent>
<!--父工程引入springcloud配置-->
<dependencyManagement>
  <dependencies>

    <dependency>
      <groupId>org.springframework.cloud</groupId>
      <artifactId>spring-cloud-dependencies</artifactId>
      <version>Edgware.SR4</version>
      <!--Dalston.SR3-->
      <type>pom</type>
      <scope>import</scope>
    </dependency>
  </dependencies>
</dependencyManagement>
子工程中pom添加

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