一、springmvc是一个mvc框架,通过mvc很好的将数据、业务、表现进行分离 二、springmvc是围绕DispatcherServlet展开的由DispatcherServlet负责将请求派发到特定的handler springmvc框架搭建步骤 1.创建项目拷贝springmvc相关的jar包。 2.配置web.xml主要配置前端控制器DispatcherServlet servletservlet-namespringmvc/servlet-nameservlet-classorg.springframework.web.servlet.DispatcherServlet/servlet-class/servletservlet-mappingservlet-namespringmvc/servlet-nameurl-pattern*.do/url-pattern/servlet-mapping3.在web-inf下创建springmvc配置文件[servletname]-servlet.xml,文件名必须是springmvc-servlet.xml4.配置HandlerMapping映射根据beanname找到对应的Controller可以省略bean classorg.springframework.web.servlet.mvc.support.ControllerBeanNameHandlerMapping5.创建jsp页面需要请求发出请求的页面6.创建Controller,继承AbstractController重写handleRequestInternal(HttpServletRequest request,HttpServletResponse response)//返回数据和页面Overrideprotected ModelAndView handleRequestInternal(HttpServletRequest request,HttpServletResponse response) throws Exception {String hello request.getParameter(file);System.out.println(hello);ModelAndView modelAndView new ModelAndView(welcome); //返回到的页面modelAndView.addObject(helloword,hello); //返回值return modelAndView;} 7.配置视图解析器!-- 配置视图解析器 --bean classorg.springframework.web.servlet.view.InternalResourceViewResolver!-- 配置前缀和后缀 --property nameprefix value//property!-- 后缀 --property namesuffix value.jsp/property/bean下面我把源码放上来吧web.xml里面的配置

/html最后看一下目录对应关系运行看welcome.jsp页面 运行完毕遇到的问题
Springmvc中提交from之后不跳转不进控制器 Could not open ServletContext resource [/WEB-INF/springmvc-servlet.xml]【解决方案】
