Я изучаю Spring STS и пытаюсь подключить DB с JPA.Соединение с пружиной STS DB с Jpa
Я не знаком с весной, поэтому у меня проблема с подключением БД.
если я добавить pom.xml этот код
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
<version>1.3.2.RELEASE</version>
</dependency>
я получаю эту ошибку

Как я могу решить эту проблему?
Поскольку вы находитесь в стадии обучения и с использованием пружинной загрузки depencies, почему бы вам не создать проект с использованием «Spring Starter Project» и начать оттуда? – Stilleur
