Spring MVC集成velocity视图解析器问题

  • spring
  • velocity

小弟最近学习搭建Spring MVC框架的web应用,工具是Myeclipse10,在配置velocity的视图解析器时遇见1奇怪问题,烦请高手解答。
问题简述:项目搭建完毕启动访问url后,最初是报 找不到layout.vm这个文件而出错,在项目里面新建该文件后,后台无报错了,但是无论Action返回视图a或b,最终都会显示layout里面的内容,从而达不到页面跳转的目的。
下面附上几张项目配置的图片供参考。
项目文件结构:

web.xml配置:

 <?xml version="1.0" encoding="UTF-8"?>
