1． sqlMapClient节点
类似SessionFactory之与Hibernate，这里我们引入了针对ibatis SqlMap的SqlMapClientFactoryBean配置。SqlMapClient对于ibatis的意义类似于Session与Hibernate以及Connection与JDBC，这里的sqlMapClient节点实际上配置了一个sqlMapClient的创建工厂类。configLocation属性配置了ibatis映射文件的名称。
2． transactionManager节点
这里我们的transactionManager配置与之前JDBC示例中相同，都采用了DataSourceTransactionManager，这与Hibernate有些差异。
3． userDAO节点
对应的，UserDAO需要配置两个属性，sqlMapClient和DataSource，sqlMapClient将从指定的DataSource中获取数据库连接。
