解决办法：加上下面这段即可

    String vmPath =ServletActionContext.getRequest().getSession().getServletContext().getRealPath("");
    Properties p = new Properties();
    p.setProperty("file.resource.loader.path", vmPath+"//");

    //初始化vm模板
    Velocity.init( p );
   Template template=Velocity.getTemplate("index.html","UTF-8");
