springmvc入门之注解方式重点解析

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 }
