如何解决我的ClassNotFoundException问题？

已完成的步骤：

添加了mvn clean -U命令
将<maven.compiler.source>1.8</maven.compiler.source>和1.8添加到父级pom中。
在IDE中所有测试都通过且没有异常。

可能是一些Spring或Hibernate配置文件的问题。我注意到它期望找到org.threeten包，但在您的依赖项中，您声明了提供类似功能但名称不同的joda-time包中的org.joda.time包。 - undefined

遇到了同样的问题，使用Java 8和Maven Shade来生成Uber-jar时发生了问题：只有在运行Uber-jar时才出现问题，在IDE上使用原始classpath时没有问题。我通过添加对threetenbp的依赖修复了问题，但这毫无意义，因为我正在使用Java 8。 - undefined

检查您的EntityManager创建配置，可能您的实体包（模型包）扫描配置出现错误或缺失。

作为错误提示信息 ClassNotFoundException 描述，你需要将未找到的依赖项包含在你的 POM 文件中。这样应该可以解决这个错误。

添加下一个依赖项解决了问题： <dependency> <groupId>org.threeten</groupId> <artifactId>threetenbp</artifactId> <version>1.3.3</version> </dependency> 但这很奇怪。 - undefined

怎么会这么奇怪呢？ - undefined

我觉得很奇怪，为什么需要这个依赖呢？毕竟spring-data应该导入它所需的所有依赖，不是吗？ - undefined

重新阅读问题后，我意识到我的评论可能不合适，因为我不知道为什么Spring Data JPA需要threeten，除非它在实体中使用，这样添加它的要求就不奇怪了。 - undefined
