[0528]2-springMVC入门准备工作2
1.修改web.xml，加入spring的请求控制器
<!-- 前端控制器 --> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!--<init-param> <param-name>contextConfigLocation</param-name> <param-value></param-value> </init-param> --></servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>*.htm</url-pattern> </servlet-mapping>
?2.根据上面的servlet-name，默认的配置bean文件：
dispatcher-servlet.xml
<bean id="viewResolver" value="/WEB-INF/jsp/" /><property name="suffix" value=".jsp" /></bean><bean name="/show.htm" />
?3.请求分发到控制LoginController
package com.iteye.niewj.controller;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.springframework.web.servlet.ModelAndView;import org.springframework.web.servlet.mvc.Controller;import com.iteye.niewj.domain.User;import com.iteye.niewj.service.UserService;public class LoginController implements Controller {private UserService<User> userService; public void setUserService(UserService<User> userService) {this.userService = userService;}@Overridepublic ModelAndView handleRequest(HttpServletRequest request,HttpServletResponse response) throws Exception {String userName = request.getParameter("userName");//String passwd = request.getParameter("passwd");//User user = (User)userService.findUser(userName, passwd);return new ModelAndView("show", "user", userName);}}??
