Spring已集成jsp的环境下同时集成Velocity 400 请求出错 

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></pre> 

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
