如何修复NoClassDefFoundError:org/hibernate/HibernateException？ 目前我正在开发一个使用Maven和Hibernate的小程序。 我写了130个Junit测试。其中一半在测试我的DAO。他们都是成功的，没有任何问题。 现在我开始编写一些REST方法，并想用Postman测试它们。问题是我得到一个异常作为响应，我不知道如何修复它。

您知道如何解决此问题吗？

错误原因是wildfly的部署文件夹中有一个空的lib文件夹。
我可以这样解决：
我重新创建了整个项目（新的maven项目，并将所有java文件从旧复制到新）。现在，所有依赖项都添加到wildfly的lib文件夹中

---

项目设置中似乎有错误

org.hibernate.HibernateException

位于pom.xml中的hibernate核心JAR中。您是如何构建和运行此应用程序的？如果您要将WAR文件复制到某个服务器，是否检查了该WAR文件是否包含hibernate-core.jar？@Arkantos：我使用服务器下的eclipse发布按钮，在那里添加了Wildfly服务器。wildfly服务器的部署文件夹中的XYZ.war文件夹中没有JAR（WEB-INF下甚至没有lib文件夹）。如果我执行“maven安装”并查看新创建的war，JAR和lib文件夹就在那里。如果我尝试手动部署此包，则会为每个http请求返回状态405。。。
