我主要写出一些重要的地方，大神勿喷，请绕道！嘿嘿
springmvc注解方式:
1.jar包；（15个包）
2.web.xml进行配置；

<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.springmvc.xml进行配置；

<mvc:annotation-driven></mvc:annotation-driven>注解驱动    <context:component-scan base-package="controller"></context:component-scan>扫描

4.创建controller；

    @Controller    public class DeptController{    @RequestMapping("/dept.action")    public ModelAndView handleRequest(HttpServletRequest request,            HttpServletResponse response) throws Exception {        ModelAndView mav=new ModelAndView();        Dept d=new Dept(1,"dage","kaifeng");        mav.addObject("dept",d);        mav.setViewName("index.jsp");        return mav;    }    }

5.编写实体类；
private int id;
private String name;
private String loc;
6.编写jsp页面；

${dept.id }-----${dept.name }-----${dept.loc }
