spring BeanCreationException：通过工厂方法实例化Bean失败嵌套异常

Question

我开始使用spring，我正在尝试使用Security、Hibernate和ThymLeaf构建一个应用程序。

我犯了一个让我困了好几天的错误。

以下是日志：

下面是我的项目结构：

如果您需要任何信息，请不要犹豫：）

Answer 1

如果应用程序中定义了任何基类，那么尝试使用

entityManagerFactoryBean.setPackagesToScan(new String[]{BaseEntity.class.getPackage().getName()});

Answer 2

请确保您的实体管理器中有正确的软件包进行扫描。

entityManagerFactory.setPackagesToScan(
    env.getProperty("entitymanager.packagesToScan")
); 

您确定在这里设置了正确的路径吗。不确定实体管理器是什么，是否正在设置扫描路径
