step3:spring-mvc.xml

1)springMVC注解驱动

2）静态资源默认servlet配置

3）视图解析器

   <!-- 配置SpringMVC -->
   <!-- 1.开启SpringMVC注解驱动 -->
   <mvc:annotation-driven />
   <!-- 2.静态资源默认servlet配置-->
   <mvc:default-servlet-handler/>

   <!-- 3.配置jsp 显示ViewResolver视图解析器 -->
   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
       <property name="viewClass" value="org.springframework.web.servlet.view.JstlView" />
       <property name="prefix" value="/WEB-INF/jsp/" />
       <property name="suffix" value=".jsp" />
   </bean>

   <!-- 4.扫描web相关的bean -->
   <context:component-scan base-package="com.kuang.controller" />

</beans>

step4:Spring配置整合文件，applicationContext.xml

   <import resource="spring-dao.xml"/>
   <import resource="spring-service.xml"/>
   <import resource="spring-mvc.xml"/>
