照着书上写的一个springMVC跳转的例子
web.xml文件是这样的：

<?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" id="WebApp_ID" version="3.0">

  <servlet>

  

  	<servlet-name>dispatcherServlet</servlet-name>

  	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

  	<!-- 初始化参数 -->

  	<init-param>

  		<param-name>contextConfigLocation</param-name>

  		<param-value>/WEB-INF/dispatcherServlet-servlet.xml</param-value>

  	</init-param>

  	<load-on-startup>1</load-on-startup>

  </servlet>

  <!-- 拦截所有以do结尾的请求 -->

  <servlet-mapping>

  	<servlet-name>dispatcherServlet</servlet-name>

  	<url-pattern>*.do</url-pattern>

  </servlet-mapping>

</web-app>

dispatcherServlet-servlet.xml文件是这样的：

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE beans PUBLIC "-//SPRING//DTD BEAN//EN" "http://www.springframeword.org/dtd/spring-beans.dtd">

<beans>

	<!-- 定义映射 -->

	<bean id="urlMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">

		<property name="mappings">

			<props>

				<prop key="helloWorld.do">helloWorldAction</prop>

			</props>

		</property>

	</bean>

	<!-- 定义视图 -->

	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">

		<property name="viewClass">

			<value>org.springframework.web.servlet.view.InternalResourceView</value>

		</property>	

	</bean>

	<!-- 定义控制器 -->

	<bean id="helloWorldAction" class="com.moon.action.HelloWorldAction">

		<property name="helloWorld">

			<value>HelloWorld</value>

		</property>

		<property name="viewPage">

			<value>/WEB-INF/jsp/index.jsp</value>

		</property>

	</bean>

</beans>

index.jsp是这样的：

<%@ page language="java" contentType="text/html; charset=utf-8"

    pageEncoding="utf-8"%>

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<html>

<head>

<meta http-equiv="Content-Type" content="text/html; charset=utf-8">

<title>Insert title here</title>

</head>

<%

String str = (String)request.getAttribute("helloWorld");

%>

<body>

	<h1><%=str %></h1>

</body>

</html>
