导入必要的架包

![Center][]

在web.xml中配置

<?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_2_5.xsd" id="WebApp_ID" version="2.5">
      <display-name>springmvc_1</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>
      </servlet>
      <servlet-mapping>
      	<servlet-name>springmvc</servlet-name>
      	<url-pattern>*.do</url-pattern>
      </servlet-mapping>
    </web-app>

在springmvc-servlet.xml中配置

<?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"
    	xmlns:aop="http://www.springframework.org/schema/aop"
    	xmlns:tx="http://www.springframework.org/schema/tx"
    	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
    	http://www.springframework.org/schema/aop
    	http://www.springframework.org/schema/aop/spring-aop.xsd
    	http://www.springframework.org/schema/tx 
    	http://www.springframework.org/schema/tx/spring-tx.xsd">
    	
    	
    	
    	
    	<bean class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping"></bean>
    	
    	
    	<bean class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
    		<property name="mappings">
    			<props>
    				<prop key="/hello1.do">mySpringMVC</prop>
    			</props>
    		</property>
    	</bean>
    	
    	
    	<bean id="mySpringMVC" name="/hello.do" class="cn.spring.controller.MySpringMVC"></bean>
    	
    	
    	<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    		<property name="prefix" value="/WEB-INF/jsp/"></property>
    		<property name="suffix" value=".jsp"></property>
    	</bean>
    </beans>

controller中

package cn.spring.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 MySpringMVC implements Controller{
    
    	@Override
    	public ModelAndView handleRequest(HttpServletRequest arg0,
    			HttpServletResponse arg1) throws Exception {
    		System.out.println("hello springmvc in controller");
    		return new ModelAndView("index");
    	}
    
    
    }

可以通过http://localhost:8080/springmvc\_1/hello1.do

和http://localhost:8080/springmvc\_1/hello.do
