Приведенный выше запрос относится к проекту, над которым я работаю:

ПРОЕКТ:

У меня есть простой проект API на основе REST, использующий SpringBoot и Hibernate, где янеобходимо создать механизм регистрации и входа в систему, используя запросы GET и POST.Всякий раз, когда я пытаюсь сделать запрос POST для создания ресурса (в этом случае создайте нового пользователя), я получаю следующую ошибку в POSTMAN, а также в Eclipse IDE:

POST REQUEST, которую я сделал с помощью POSTMAN 

{
    "userId": "12345",
    "pin": "1234"
}

Изменить @SpringBootApplication на 

@SpringBootApplication(exclude=HibernateJpaAutoConfiguration.class)

С выпуском Hibernate 5.2 SessionFactory расширяет интерфейс EntityManagerFactory.Это приводит к тому, что SessionFactory также является EntityManagerFactory.

В предыдущих выпусках гибернации это было не так.

Простое решение - понизить версию гибернации до версии <5.2, поскольку существуетнет решения для Spring 5.0 (будет в Spring 5.1). </p>

Вы можете обратиться 1 2 , чтобы узнать больше

РЕДАКТИРОВАТЬ:

Когда вы пишете exclude=HibernateJpaAutoConfiguration.class в результате

@ SpringBootApplication

не будет считать, чтоособый класс для дальнейшего исполнения.Как вы можете видеть на изображении HibernateJpaAutoConfiguration, уже реализованы некоторые классы (которые могут реализовывать другие), для которых вам не нужно ничего настраивать или упрощать использование, например, LocalContainerEntityManagerFactoryBean.class.Поскольку вы исключили класс, вы должны будете вручную делать то, что HibernateJpaAutoConfiguration.class сделал для вас.
