1. @Transaction 事务

TransactionSynchronizationManager

用以存储并维护SqlSessionHolder，存于ThreadLocal中，待持久层框架Mybatis在获取SqlSession时直接使用此缓存下的SQLSession，mybatis关sqlsession时也在此release，并非真正意义的关闭；

2. @Async 异步

3. @Scadular 定时任务

4. Yml转换

4.1. YamlPropertiesFactoryBean

YamlPropertiesFactoryBean可以设置一个或一组Resource，通过在需要时通过getObject()可以解析得到Properties配置
