springmvc实现，环境搭建

1，jar包
spring3.0.0的dist的所有jar包+commoms-logging-1.1.1.jar
2，配置web.xml
<servlet>
   <servlet-name>hello</servlet-name>
   <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/classes/hello-servlet.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
   <servlet-name>hello</servlet-name>
   <url-pattern>/</url-pattern>
  </servlet-mapping>
3，在src下创建xml文件
文件名必须为：hello-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: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-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="com"  />
   <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
   <property name="prefix" value="/WEB-INF/jsp/"></property>
   <property name="suffix" value=".jsp"></property>
   </bean>

</beans>

4，
在hello-servlet.xml中配置
<bean name="/welcome.html" class="com.controller.WelcomeController">


5，
package com.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;
public class WelcomeController extends AbstractController {

@Override
protected ModelAndView handleRequestInternal(HttpServletRequest arg0,
   HttpServletResponse arg1) throws Exception {
  System.out.println("helloworld");

  return new ModelAndView("welcome");
}

}
