为什么我得到这个NoClassDefFoundError？

标签： java spring maven pom.xml

突然间，我在春季应用程序中收到了以下错误，我看不出原因。我不相信我已经改变了我的pom.xml文件中的任何内容。有没有人对如何解决这个问题提出任何想法？

错误：

2 个答案:

答案 0 :(得分：3)

我重命名了我的.m2目录并重新运行了maven构建，这解决了这个问题。缓存显然在某种程度上被破坏了。

答案 1 :(得分：1)

您正在混合不同版本的Spring组件。例如，你有spring-orm 4.0.2.RELEASE和spring-beans 4.0.3.RELEASE。

我看到你也在使用spring-data-rest-webmvc和spring-data-jpa。这些依赖关系也可能会引入Spring依赖项的非预期版本。您可以向这些依赖项添加排除项，以防止这种情况发生。
