freemarker與springMvc整合的坑

//這是controller
@Controller
@RequestMapping()
public class PageController {

    @RequestMapping(value = "/page/index",method={RequestMethod.GET})
    public ModelAndView index(){
        ModelAndView mav=new ModelAndView();
        mav.addObject("name","youmu daisuki");
        mav.setViewName("index");
        return mav;
    }

}

我試過後一直報

我看了有這個檔案啊，我跟源碼後發現路徑變成了WEB-INF/ftl/index.ftl，怎麼說應該是/WEB-INF/ftl/index.ftl的啊。後來我把

FreeMarkerConfigurer 的< property name ="templateLoaderPath" value ="" ></ property > 加上去就好了...我又試了試去掉prefix也不行，估計是這兩個都有null判斷（不是blank判斷）。希望碼友們少踩這個坑。。。
