SpringMVC初识视图解析器

<!--视图解析器-->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!--前缀-->
        <property name="prefix" value="/"/>
        <!--后缀-->
        <property name="suffix" value=".jsp"/>
    </bean>

　　

创建一个类实现Controller接口

package cn.happy.day01;

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

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

//处理器类
public class FirstController implements Controller {
    public ModelAndView handleRequest(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
        ModelAndView mv = new ModelAndView();
        //视图名称
        mv.setViewName("index");
        return mv;
    }
}
