简单搭建springmvc架构

第一步：

         在web.xml中配置springmvc的前端控制器。

  <servlet>
    <servlet-name>spring</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

第二步:

        导入必须的jar包：spring.jar;spring-webmvc.jar;commons-logging.jar;

第三步：

        开发自己的实现Controller类  例

public class HelloController implements Controller {

	protected final Log logger = LogFactory.getLog(getClass());

    public ModelAndView handleRequest(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        logger.info("Returning hello view");

        return new ModelAndView("hello.jsp");
    }



}

最后一步:

       在web-inf目录下，创建自己的spring-servlet.xml文件，并配置Controller ：

<?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-2.5.xsd     
       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd   
       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">   
     
 	<bean name="/hello.do" class="com.eastcom.web.action.HelloController">
 	</bean>
  
 </beans> 

 ps：spring-servlet.xml文件的命名规则为xxx-servlet.xml。xxx为web.xml中前端控制器DispatcherServlet的名字，这点要注意。
