springmvc入門之註解方式重點解析

我主要寫出一些重要的地方，大神勿噴，請繞道！嘿嘿
springmvc註解方式:
1.jar包；（15個包）
2.web.xml進行配置；

<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進行配置；

<mvc:annotation-driven></mvc:annotation-driven>註解驅動
    <context:component-scan base-package="controller"></context:component-scan>掃描

4.創建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.編寫實體類；
private int id;
private String name;
private String loc;
6.編寫jsp頁面；

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