ssm整合

一、配置文件的分工

　　spring配置文件：

　　　　1、配置扫描包,排除Controller、ControllerAdvice

　　　　2、导入属性文件

　　　　3、数据库连接池的数据源

　　　　4、配置事务管理器（datasource属性）

　　　　5、开启基于注解的事务<tx:annotation-driven transaction-manager="dataSourceTransactionManager"/>

　　　　6、配置SqlSessionFactoryBean对象，（dataSource和configLocation属性）

　　　　7、配置MapperScannerConfigurer对象（basePackage属性：mapper包扫描）
