本文详细介绍如何在Spring MVC框架中整合Velocity模板引擎，包括配置Velocity解析视图、设置资源加载路径、配置DispatcherServlet以及处理页面请求等关键步骤。

为什么80%的码农都做不了架构师？>>>

1、集成使用的jar:Spring 3.0.5 ,Velocity-1.7,velocity-tools-1.4

2、配制后缀(*.vm)映射。修改web.xml，添加如下代码

<servlet>
    	 <servlet-name> my</servlet-name>
	<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
     	<load-on-startup>2</load-on-startup>
	</servlet>
	
	<servlet-mapping>
	    <servlet-name> my</servlet-name>
	    <url-pattern>*.vm</url-pattern>
	</servlet-mapping>

并相应的创建一个my-servlet.xml(webapp\WEB-INF\my-servlet.xml),因为DispatcherServlet会去找这个配制文件并初始化，这个相当重要。

3、配制解析*.vm的请求

<?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/context http://www.springframework.org/schema/context/spring-context-2.5.xsd">
    <!-- 配制velocity的解析视图 -->
    <!-- VelocityResolver 继承Spring的VelocityViewResolver,并扩展其layout模版布局 -->
    <bean id="viewResolver2" class="com.my.velocity.VelocityResolver">
	   <property name="prefix" value="/WEB-INF/jsp/" />
	   <property name="suffix" value=".vm" />
	   <property name="contentType" value="text/html;charset=UTF-8" />
	   <!-- VelocityLayoutView 继承 Spring的VelocityToolboxView,用于支持toolbox.xml中的类  -->
       <property name="viewClass" value="com.my.velocity.VelocityLayoutView" />  
       <property name="layoutUrl" value="/WEB-INF/velocity/layout/default.vm"/>
       <property name="layoutKey" value="layout"/>
       <property name="layoutDir" value="/WEB-INF/velocity/layout/" />
       <property name="toolboxConfigLocation" value="/WEB-INF/velocity/toolbox.xml"/> 
     </bean>
     <!-- velocity的本身配制 -->
     <bean id="velocityConfig" class="org.springframework.web.servlet.view.velocity.VelocityConfigurer">
	<property name="resourceLoaderPath" value="/" />
	<property name="configLocation" value="/WEB-INF/velocity/velocity.properties"/>
     </bean>
    <!-- 配制 *.vm 解析UIRI相对应的Controller类-->
    <import resource=" dispatcher-servlet-my.xml"/>
</beans>

4、页面请求与表单处理（/WEB-INF/dispatcher-servlet-blog.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:aop="http://www.springframework.org/schema/aop"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
       http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-2.5.xsd">
    <bean name="/my/*.vm" class="com.my.blog.controller.DiaryController">
    	<property name="diaryService" ref="diaryService" />
    </bean>
</beans>

如：显示 /blog/user/diary_cata.vm的数据，在DiaryController.java写一个如下方法即可:

public ModelAndView diary_cata(HttpServletRequest req,HttpServletResponse resp){
        ModelAndView mv = new ModelAndView("blog/diary/diary_cata");
        return mv;
    }

提交表单数据同理：

public ModelAndView save_diary(HttpServletRequest req,HttpServletResponse resp){
        ModelAndView mv = new ModelAndView("blog/diary/save_diary");
        return mv;
    }
