java.lang.NoClassDefFoundError：org / springframework / web / method / annotation / ExceptionMethodMapping

Question

我在Spring mvc 3.0中学习使用注释验证表单。 当我将<mvc:annotation-driven />添加到我的*** - servlet.xml时，我在启动eclipse后得到以下错误：

这些是我添加的罐子：

这是我的*** - servlet.xml

</beans>

我错过了什么？

Answer 1

做了一些研究，你是对的，ExceptionMethodMapping类似乎无法在任何spring-web 3.x（或4.x）中找到。

但是如果你看一下关于这个课程的Spring revisions，它似乎已经在2011年9月删除了。所以很可能你的一个依赖关系与你的春天没有“同步”（及时说话） -web依赖（奇怪的是，除了你的spring-ws之外，它们似乎都在3.1.4中）。我建议你将所有依赖项更新为相同版本，如果它是你的选项，请远离3.1并转到Spring 3.2。
