1 1.web.xml
2 <servlet>
3 <servlet-name>dispatcherServlet</servlet-name>
4 <servlet-class>
5 org.springframework.web.servlet.DispatcherServlet</servlet-class>
6 <init-param>
7 <param-name>contextConfigLocation</param-name>
8 <!-- 修改了加载xml的位置 -->
9 <param-value>classpath:spring-servlet.xml</param-value>
10 </init-param>
11 <load-on-startup>1</load-on-startup>
12 </servlet>
13 <servlet-mapping>
14 <servlet-name>dispatcherServlet</servlet-name>
15 <url-pattern>*.do</url-pattern>
16 </servlet-mapping>
17 2.spring-servlet.xml（若上面没有配置contextConfigLocation，默认WEB-INF/dispatcherServlet.xml）
18 2.1.自动扫描包：<context:component-scan base-package="cn."></context:component-scan>
19 2.2.开启注解：<mvc:annotation-driven />或<context:annotation-config />
2.4.<!-- 定义跳转的文件的前后缀，可以在Controller中return "index"跳转到/WEB-INF/jsp/index.jsp页面 -->
<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
20 3.添加注解（如：@Controller）
