spring-Security项目中的pom.xml文件中, spring io和spring cloud的版本spring官网和老师的不一样, 我用的官网的版本, 但是为什么就报那个错误呢:

<dependencyManagement>
<dependencies>
<!-- spring io来进行jar的版本的管理, 而不用去考虑jar包版本之间的兼容性问题 -->
<dependency>
<groupId>io.spring.platform</groupId>
<artifactId>platform-bom</artifactId>
<version>Brussels-SR5</version>
<type>pom</type>
<scope>import</scope>
</dependency>
<!-- spring cluoud 进行jar的版本管理 -->
<dependencies>
<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-dependencies</artifactId>
<version>Dalston.SR4</version>
<type>pom</type>
<scope>import</scope>
</dependency>
</dependencies>
</dependencies>
</dependencyManagement>

  imooc-security-core配置依赖, 指定jar版本就好了...否则cloud的jar下载不下来...为毛啊         
  <dependency>
  			<groupId>org.springframework.cloud</groupId>
  			<artifactId>spring-cloud-starter-oauth2</artifactId>
  			<version>1.2.1.RELEASE</version>
  		</dependency>
