springMVC环境搭建

首先导入相应jar包，然后在web.xml里配置：

<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*:config/spring-servlet.xml</param-value>
  	</init-param>
  	<load-on-startup>1</load-on-startup>
  </servlet>
  
  <servlet-mapping>
  	<servlet-name>springMVC</servlet-name>
  	<url-pattern>/</url-pattern>
  </servlet-mapping>

 然后，新建一个springMVC的配置文件spring-servlet.xml，最好是新建一个package包config(如上param-value的配置)，然后把所有配置文件都放进去，这样不同的人写的配置文件都在一起，便于管理。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"  
 xmlns:context="http://www.springframework.org/schema/context"  
 xmlns:p="http://www.springframework.org/schema/p"  
 xmlns:mvc="http://www.springframework.org/schema/mvc"  
 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  
 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.xsd  
      http://www.springframework.org/schema/mvc  
      http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
      
	<bean name="/test/helloworld" class="com.web.controller.HelloWordController" />
	<bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
		<property name="prefix" value="/"></property>
		<property name="suffix" value=".jsp"></property>
	</bean>
 </beans>  

 最后，就可以写业务类了(如上的com.web.controller.HelloWordController)，注意：业务类需实现Controller接口，来自import org.springframework.web.servlet.mvc.Controller
