1.【上机】配置mvc环境
2.【上机】使用注解的方式实现Spring MVC的参数的传递(页面上传入和传出)

<!-- 1.配置注解 -->
<context:annotation-config></context:annotation-config>
<context:component-scan base-package="renjiale"></context:component-scan>
<!-- 2.MVC的注解配动 -->
<mvc:annotation-driven></mvc:annotation-driven>
<!-- 3.配置viewresovler视图处理器 -->
<!-- rest风格: http://域名/index.jsp -->
<bean id="myspringmvc" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/"></property>
<property name="suffix" value=".jsp" ></property>
<!-- 根据前缀和后缀找到对应的页面,OK -->
</bean>
<!-- 4. 编写代码-->
<!-- 5.配置dispatcherServlet(MVC)自动配置;在web.xml配置servlet -->
<!-- 6.编写servlet -->
<bean id="dispatcherServlet" class="org.springframework.web.servlet.DispatcherServlet"></bean>
<!-- 7.编写测试代码-jsp页面 -->
<!-- 8.MVC处理请求,编写业务类 -->
<!-- 9. 当在.jsp点击请求,让业务类中的方法来处理请求 -->
<!-- 10.controller使用注解实现控制器 -->
<!-- 11.jsp请求找多个业务类 @RequestMapping 找对应的方法@RequestMapping-->
<!-- 12.请求后.jsp页面跳转到指定地方 -->

4.【上机】实现Spring MVC和AJAX的交互，包括接收json请求参数
5.【上机】使用Spring MVC实现文件上传
6.【上机】Spring MVC使用二种方式实现自定义拦截器
7.【上机】使用自定义拦截器实现用户登录验证
8.【上机】集成Spring与Spring MVC
9.【上机】集成Spring与Spring MVC加JDBC，实现对用户的CRUD操作
