Question

我最近将Spring Framework的版本从Spring 2.5更新到3.1.3。

但是现在，当我运行我的应用程序时，会出现一条错误消息：

我试图搜索此错误，但似乎关于它的信息很少。有没有人有想法？

感谢。

查看Spring 3.0 API显示缺少的类不是版本3.x的一部分。我假设您的一个Spring Jar文件仍在使用2.5版本。查看您的pom.xml文件以尝试发现哪个Jar仍在使用此版本。

密切关注此list中的任何广告。

java.lang.NoClassDefFoundError：org / springframework / metadata / Attributes
