com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: сбой канала связи И ошибка BeanEntityManager

Question

Пришлось вырезать первое сообщение об ошибке совсем немного, так как оно содержало много символов, но полное описание можно найти здесь: https://github.com/kableiv/FullSpringError

Бит предыстории: Выполнение задания и создание небольшого веб-сайта, на котором могут войти 2 предопределенных пользователя, один с правами пользователя и один с правами администратора. Это кнопки, которые перенаправляют вас на страницы, на которых вы редактируете, удаляете и регистрируете новую информацию. Сначала я делал это без весенней безопасности и без базы данных, используя массивы и файлы. Когда я вошел в систему с пользователем, у него были только те привилегии пользователя, которые предполагались, однако, когда я вошел в систему с администратором, а затем перешел на любую другую html-страницу, например ту, которая использовалась для редактирования чего-либо, а затем нажала на кнопку возврата. Кнопка, права администратора исчезли. Я предполагаю, что это потому, что я, в моем методе для входа в систему, установил для своего административного значения значение true (чтобы html-страница знала, что отображать, а что нет), а затем, когда этот метод был выполнен, а новый запускался, как метод редактирования. значение вернулось к нулю.

Из-за этого я решил попробовать перейти на использование базы данных MySQL с пружинной безопасностью. Моя IDE выбрана intellij ultimate, и я использовал MySQL Workbench для настройки базы данных и добавил ее в intellij, используя функцию базы данных.

Теперь при попытке запустить проект я получаю следующую ошибку:

СЕЙЧАС Я также избавился от этой вещи (хотя не уверен, что сделал все правильно), но это выглядело как ошибка, но я попросил определить компонент типа package. Я решил убрать зависимости и поэтому сейчас с первой ошибкой поста сижу.

Ниже мой UserRepository: Перевод: BrugerRepository is (UserRepository)

import org.springframework.stereotype.Repository;

@Repository
public interface BrugerRepository extends CrudRepository<MinBruger, String> {

}

Как я могу это исправить? Заранее спасибо.

Answer 1

ОБНОВЛЕНИЕ: Хорошо, поэтому я сел собственности:

spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect

Помимо этого я также изменил следующее:

spring.datasource.url=jdbc:mysql://localhost:3306/

TO:

spring.datasource.url=jdbc:mysql://localhost:3306/test_db?useSSL=false

Похоже, это было частью уловки, мой проект теперь запускается, однако возникает новая проблема, при попытке входа в систему он терпит неудачу и устанавливает URL-адрес из: http://localhost:5000/login

TO: http://localhost:5000/login?error
