<dependency>
    <groupId>org.springframework.security</groupId>
    <artifactId>spring-security-oauth2-authorization-server</artifactId>
    <version>1.2.0</version>
</dependency>

<!-- 添加spring security cas支持
 这里需添加spring-security-cas依赖，
 否则启动时报java.lang.ClassNotFoundException: org.springframework.security.cas.jackson2.CasJackson2Module错误。
