自从我学习编程以来，这是我第一次在这里写作。我正在使用Spring Boot启动一个个人项目，这已经3天了，面临着严重的问题。不管我在哪里看，甚至是较老的问题或相关问题，我都始终面临着同样的问题。
这可能将是一件“愚蠢的”事情，但是我无法找到并解决我的错误。错误如下：
在上下文初始化期间遇到异常-取消刷新尝试：org.springframework.beans.factory.BeanCreationException：在类路径资源[com / proyecto / springbootapp / config / PersistenceJPAConfig.class]中创建名称为'entityManagerFactory'的bean时出错：调用init方法失败；嵌套的异常是java.util.NoSuchElementException
我知道没有生成我的entityManagerFactory，但是我不明白为什么不生成它。我一直在按照本教程进行存档：https://www.baeldung.com/the-persistence-layer-with-spring-and-jpa
我的休眠实体不好吗？也许是由于某些pom依赖关系？我已尽力而为，但无法检测出我的问题到底在哪里。
代码和数据库都可以在这里找到
