Когда я запускаю приложение springboot, я получаю сообщение об ошибке

field materialRequestRepo in com.sql.csse.ControllerManager.MaterialRequestController required a bean named 'entityManagerFactory' that could not be found.

и я искал ответ, и я нашел этот

Как вы можете видеть в ответе на вопрос, он попросил удалить

<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-core</artifactId>
<version>4.1.4.Final</version>
</dependency>
<dependency>
<groupId>org.hibernate</groupId>
<artifactId>hibernate-entitymanager</artifactId>
<version>5.2.3.Final</version>
</dependency>

Но в моем случае, когда я удаляю эти dependencies я получаю сообщение об ошибке,

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [org/springframework/boot/autoconfigure/orm/jpa/HibernateJpaConfiguration.class]: Invocation of init method failed; nested exception is org.hibernate.service.spi.ServiceException: Unable to create requested service [org.hibernate.engine.jdbc.env.spi.JdbcEnvironment]

И для этой проблемы, как вы можете видеть здесь, они попросили добавить те же самые зависимости, которые я удалил ранее.

В чем может быть проблема?
