项目结构截图如下，该项目由maven构建的web项目，实例简单，无数据库连接操作，功能演示的请求地址分别在controller包下的三个类中，本例中的请求地址为：
http://localhost:8080/spring-mvc-velocity-bootstrap/greet --默认欢迎
http://localhost:8080/spring-mvc-velocity-bootstrap/greet/zhangsan --欢迎某人，这里是zhangsan，可任意
http://localhost:8080/spring-mvc-velocity-bootstrap/hello --默认hello
http://localhost:8080/spring-mvc-velocity-bootstrap/hello-world --hello world
http://localhost:8080/spring-mvc-velocity-bootstrap/hello-redirect --重定向到hello world请求
http://localhost:8080/spring-mvc-velocity-bootstrap/user/zhang/san.json --请求参数为json格式
http://localhost:8080/spring-mvc-velocity-bootstrap/user/zhang/san.xml --请求参数为xml格式
该项目为简单的springmvc+velocity+rest service，且无数据库连接操作，下面给出controller包下的请求配置，和spring的xml文件配置，和velocity的模板配置，和web.xml的加载，监听配置。
三个controller类的请求配置的代码依次为：

}

然后是三个velocity的模板和属性文件的配置：
#define($content)
<p>#springMessage("Hello"): $name</p>
<p>#springMessage("Greetings")</p>
#end#define($content)
#springMessage("Hello")
#end#set($page_title="#springMessage(‘HelloWorld‘)")
#define($content)
#springMessage("HelloWorld")
