SpringMVC配置（eclipse）

工程结构

第一总配置

web.xml 文件

<?xml version="1.0" encoding="UTF-8"?> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xsi:schemaLocation="http://java.sun.com/xml/ns/javaee     http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">     <display-name></display-name>     <servlet>        <servlet-name>SpringMVC</servlet-name>        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>        <!-- springmv配置文件 -->        <init-param>            <param-name>contextConfigLocation</param-name>            <!-- springmvc配置文件路径 -->            <param-value>classpath:springmvc.xml</param-value>        </init-param>     </servlet>     <servlet-mapping>        <servlet-name>SpringMVC</servlet-name>        <url-pattern>/</url-pattern>     </servlet-mapping>     <welcome-file-list>        <welcome-file>index.jsp</welcome-file>     </welcome-file-list> </web-app>

springmvc.xml 配置文件

<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans"     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"     xmlns:p="http://www.springframework.org/schema/p"     xmlns:context="http://www.springframework.org/schema/context"     xsi:schemaLocation="         http://www.springframework.org/schema/beans         http://www.springframework.org/schema/beans/spring-beans.xsd         http://www.springframework.org/schema/context         http://www.springframework.org/schema/context/spring-context.xsd">               <!--1 配置处handlerMapping映射器（默认）-->        <!-- 根据bean的name 属性映射用户请求 找控制器-->        <bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>               <!-- 2配置适配器 handlerAdapter适配器 执行控制器--><!-- 注意：这个适配器不是必须配置的，这是默认的、他在servlet容器已启动就被加载。 -->        <bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter"></bean>               <!-- 3 配置控制器，name="holle" 方便映射器查找地址蓝输入,定义类实现Controller接口-->        <bean name="/holle" class="com.springmvc.controller.MySpringMVCController"></bean>              </beans>

MySpringMVCController  拦截器

package com.springmvc.controller; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.mvc.Controller; public class MySpringMVCController implements Controller{     @Override     public ModelAndView handleRequest(HttpServletRequest request,HttpServletResponse response) throws Exception {        // 封裝对象        ModelAndView mav=new ModelAndView();        mav.addObject("name","张三");        request.setAttribute("uname", "李四");        //定义返回的视图,页面        mav.setViewName("/WEB-INF/jsp/main.jsp");                      return mav;     } }
