在使用注解的情况下,系统启动时会被自动扫描,并添加到bean工厂中,省去了配置文件中写bean定义
1.启动mvc注解驱动
<mvc:annotation-driven />
2.组件扫描
<context:component-scan base-package="....">
在xml配置了这个标签后,spring可以自动去扫描base-package下面或者子包下面的java文件,如果扫描到有@Component @Controller @Service等这些注解的类,则把这些类注册为bean,不用在配置文件中配置bean
3.ViewResolver、View映射关系
4.拦截器配置
5.国际化配置
<bean id ="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource">...
