<!--配置启用HandlerMapping组件:使用注解的方式@RequestMapping -->
<mvc:annotation-driven/> <!--配置视图解析器 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!--配置ViewResolver的前缀prefix和后缀suffix参数 viewResolver通过解析ModelAndView对象获取viewName视图名,然后根据公式 :prefix+viewName+suffix定位页面地址 -->

<property name="suffix" value=".jsp"></property>
</bean> <!--配置组件扫描器,扫描controller包,将使用@Controller注解的类注册成bean保存在spring容器中 -->

扫描包下的所有实体类,将该实体类的全限定类名起别名,该别名的命名方式即为:类名称
