vaadin+spring 各负其职

       昨天一天整理vaadin+spring mvc+jpa 这套东西。今天算是有点眉目了。一直搞总是弹出Failed to load the widgetset  的alert框。怎么弄就是搞不定。我一直以为mvc的servlet和vaadin的servlet有冲突。所以改他们的url。总是注销掉spring的servlet之后vaadin就可以用了。加上vaadin的servlet又不能使用了。郁闷啊。后来我发现是servlet-maping的url问题.以前写/vaadin/*就是不能用总是弹出alert框。然后改成/VAADIN/*之后就可以用了。也不知道为什么。莫非spring本身对vaadin有支持？这个就不得而知了。

ps:

可能是mvc得注释扫描不能和Vaadin的Application在同一个包下

 

附上web.xml:
