java - NoClassDefFoundError: org/hibernate/service/ServiceRegistry
问题描述
我不知道为什么在我的 Servlet 中出现此错误，但在我的测试类中却没有：java.lang.NoClassDefFoundError: org/hibernate/service/ServiceRegistry
我有休眠 5.1.14
servlet 如下。代码在BookDAO dao = DAOUtilities.getBookDAO();. 我进行了测试，它实际上在我所有的 DAO 上都崩溃了。它只是获取一个数据访问对象（DAO），以便我可以检索数据库中的所有书籍。我还将包括工作测试类以进行比较。如果您需要查看其他内容，请告诉我。
编辑：我没有使用 Maven（至少在不知情的情况下）。我正在手动添加 JAR。

解决方案
您是否在 pom.xml 中添加了 hibernate-core 依赖项？
如果不添加这样的东西
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>5.x.x</version>
</dependency>
