springmvc 1 扫描controller注解 2 <mvc:annotation-driven>添加消息转换器及适配器，映射器等3，视图转换器
spring application-dao.xml 1. 注解扫描 排除controller扫描 2. 数据源 3.sessionFactory（下面有dataSourse，hibernateProperties,annotatedClasses注解实体类）
application-tx.xml 1.transctionManager (sessionFactory) 2.<tx:adviceid="txAdvice" transaction-manager="transactionManager">遇见save.*开头的开启事物
3.aop
mybatis.cfg.xml <configuration>
<configuration>
//为了可以在result中类名小写
<package name="com.bjsxt.rbac.vo"/>
<configuration>
<configuration>
一个mapper接口对应一个mapper.xml
mapper接口写接口 mapper.xml配置<mapper namespace="mapper类全路径">
<selete id="方法名' parametertype="参数类型"result="映射的实体类（类名小写）"></>

与ss+hibernate不同点在spring容器中注入sqlsession对象和mybaties的包扫描器即可，<bean id="sqlsessionFactory" class=>
< property name="dataSourse" >
< property name="configLocation" value="mybatis.cfg.xml' >
</>
包扫描器<bean class="...MapperScannerConfigurer'>
<property name="basePackage" value="com.bjsxt.demo.mapper">
<property name="sqlSessionFactoryBeanName' value="sqlSessionFactory'>
