Springmvc框架环境的配置(入门程序编写)

第一步，前端控制器DispatcherServlet的配置

在web.xml中配置前端控制器：

springmvc org.springframework.web.servlet.DispatcherServlet contextConfigLocation classpath:springmvc.xml springmvc *.do

第二步，配置处理器映射器HandleMapping

在springmvc.xml中添加约束以及配置处理器适配器、处理器、处理器映射器、视图解析器：

编写处理器

package com.ssm.controller;/** * */import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;import javax.servlet.*;public class MyController implements Controller { @Override public ModelAndView handleRequest(javax.servlet.http.HttpServletRequest httpServletRequest, javax.servlet.http.HttpServletResponse httpServletResponse) throws Exception { ModelAndView modelAndView=new ModelAndView(); //相当于request.setAttribute()方法。 modelAndView.addObject("hayabusa","隼龙"); modelAndView.setViewName("index.jsp"); System.out.println("jdsjad"); return modelAndView; }}

编写视图
