<! - 10.1 = add MVC drive ->

<mvc:annotation-driven/>

<context:component-scan base-package="com.nana.blog.admin.controller"/>

<! - 10.3 = add MVC Routing ->

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/views/"/>
<property name="suffix" value=".jsp"/>
</bean>
<mvc:view-controller path="/showLogin" view-name="login"/>

15: Adding a database mapping file mapper, see mybatis copy xml format
17: Adding a service interface class
18: Adding impl achieve service interface
- declare @Service,
- declared the @Transactional (propagation, rollbackFor)
- injected Dao
19: Web module adds the Controller
- statement @Controller
- page path statement @@ RequestMapping map
- injected @Autowired Object services
20: bind model.addAttribute front-end data processing
