spring cloud 错误

** WARNING ** : Your ApplicationContext is unlikely to start due to a @CompoonentScan of the default package

启动类不能直接放在默认的包（src/main/java）下面，要建一个包（随意，这里键的是com.cloud.main）存放。

 java.lang.ClassNotFoundException: org.springframework.boot.context.embedded.FilterRegistrationBean

springboot的版本是

	<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>1.5.2.RELEASE</version>
  </parent>

spring cloud 的版本要是

<dependencyManagement>
    <dependencies>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-dependencies</artifactId>
            <version>Camden.SR6</version>
            <type>pom</type>
            <scope>import</scope>
        </dependency>
    </dependencies>
</dependencyManagement>

然后加上

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

就解决了。
