SpringMVC的基本操作

　　第一，就是引入依赖jar包。

      第二，编写一个web工程

       在用到SpringMvc的话我们不在编写servlet这个文件了

    1.编写一个类

      

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class FirstController implements Controller {
    public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView ma = new ModelAndView();
        ma.setViewName("/index.jsp");
        return ma;
    }
}

 

    2，在springxml中添加这样一行bean节点

   <bean id="/xxx" class="cn.mvc.dome1.FirstController"></bean>

 

     3,在web.xml中编写代码

  

 <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:applicationContext.xml</param-value>
   </init-param>
     <load-on-startup>1</load-on-startup>
   </servlet>
  <servlet-mapping>
    <servlet-name>springMvc</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

  

4，通过测试我们可以不用servlet就可以响应jsp动态页面

结束....
