**1.导入springmvc的jar包；
2.导入web.xml文件；**

<servlet>    <servlet-name>springmvc</servlet-name>    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>    <init-param>      <param-name>contextConfigLocation</param-name>      <param-value>classpath:springmvc.xml</param-value>    </init-param>  </servlet>  <servlet-mapping>    <servlet-name>springmvc</servlet-name>    <url-pattern>*.action</url-pattern>  </servlet-mapping>

3.导入springmvc.xml文件；

<bean   class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean><bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean><bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"></bean><bean name="/showDept.action" class="controller.DeptController"></bean>

4.写controller代替action，继承controller；

public ModelAndView handleRequest(HttpServletRequest request,        HttpServletResponse response) throws Exception {        Dept d=new Dept();        d.setDeptno(1);        d.setDname("kaifabu");        d.setLoc("zhengzhou");        ModelAndView mav=new ModelAndView();        mav.setViewName("index.jsp");        mav.addObject("dept",d);        return mav;}

5.写实体类；重点内容
