本文介绍了一个简单的Spring MVC应用示例，包括控制器IndexController的实现、配置文件springmvc-servlet.xml的内容以及web.xml中DispatcherServlet的配置。通过访问'http://127.0.0.1:8088/springmvc/index'可以展示带有'Hello Spring MVC'消息的页面。

IndexController类

package controller;

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

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class IndexController {
    @RequestMapping("/index")
    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response) throws Exception {
        ModelAndView mav = new ModelAndView("index");
        mav.addObject("message", "Hello Spring MVC");
        return mav;
    }
}

springmvc-servlet.xml

    <?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:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
    http://www.springframework.org/schema/context        
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">

    <context:component-scan base-package="controller" />
    <bean id="irViewResolver"
        class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <property name="prefix" value="/WEB-INF/page/" />
        <property name="suffix" value=".jsp" />
    </bean>

web.xml代码

        <?xml version="1.0" encoding="UTF-8"?>
        <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0">
          <display-name>spring-mvc-day05</display-name>
          <welcome-file-list>
            <welcome-file>index.html</welcome-file>
            <welcome-file>index.htm</welcome-file>
            <welcome-file>index.jsp</welcome-file>
            <welcome-file>default.html</welcome-file>
            <welcome-file>default.htm</welcome-file>
            <welcome-file>default.jsp</welcome-file>
          </welcome-file-list>
          <servlet>
               <servlet-name>springMVC</servlet-name>
               <servlet-class>
                   org.springframework.web.servlet.DispatcherServlet
               </servlet-class>
               <init-param>
                    <param-name>contextConfigLocation</param-name>
                    <param-value>classpath:spring-mvc.xml</param-value>
               </init-param>
               <load-on-startup>1</load-on-startup>
          </servlet>
          <servlet-mapping>
               <servlet-name>springMVC</servlet-name>
               <url-pattern>*.do</url-pattern>
          </servlet-mapping>
        </web-app>

启动后打开页面
http://127.0.0.1:8088/springmvc/index
