【引入包】
1/spring-framework-3.1.1.RELEASE-with-docs.zip/dist/下的所有jar包拷贝到项目的WEB-INF/lib目录下。
2/Spring 框架依赖的 jar 包commons.logging-1.1.1.jar。
3/需要添加 jstl 标签库支持 jstl-1.1.2.jar 和 standard-1.1.2.jar。

<!-- 配置controller,使用默认的银映射处理器来映射controller-->

<!--
配置ViewResolver 视图解析器
viewClass：JstlView 表示 JSP 模板页面需要使用 JSTL 标签库，classpath 中必须包含 jstl 的相关 jar 包；
-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>

基于注解的springMVC配置
-----------------------------------------------------------------------------------
1/【web.xml】
<servlet>
<servlet-name>chapter2</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>chapter2</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<!-- POST中文乱码过滤器 -->
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
</filter>
2/【spring.xml】只保留视图解析器
springXML命名规则：chapter2-servlet
<!--
配置ViewResolver 视图解析器
viewClass：JstlView 表示 JSP 模板页面需要使用 JSTL 标签库，classpath 中必须包含 jstl 的相关 jar 包；
-->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/jsp/"/>
<property name="suffix" value=".jsp"/>
</bean>
<mvc:annotation-driven/>
<!-- 有扫描器，注解驱动就不用写了 -->
<context:component-scan base-package="cn.springmvc.controller"/>
3/【注解使用】
controller类使用
@Controller() //标识是springmvc的处理器类
@RequestMapping("controller1") //controller的唯一标识或者命名空间
方法使用@RequestMapping("/toTest7.do")标识
