Я пытаюсь настроить бэкэнд своей Springboot для соединения с работающей базой данных mariadb с таблицей 'drug' в базе данных 'aah4_drugs'
Я пытаюсь использовать хранилище MedicineService и Medicine для созданиявызов к существующей внешней базе данных.
Однако проблема была связана с автопроводкой. Я добавил @EnableJpaRepositories, и теперь у меня появляется следующая ошибка:
Error starting ApplicationContext. To display the conditions report re-run your application with 'debug' enabled.
2019-10-21 21:51:14.513 ERROR 31242 --- [ restartedMain] o.s.b.d.LoggingFailureAnalysisReporter :
***************************
APPLICATION FAILED TO START
***************************
Description:
An attempt was made to call a method that does not exist. The attempt was made from the following location:
org.hibernate.cfg.annotations.EntityBinder.processComplementaryTableDefinitions(EntityBinder.java:1236)
The following method did not exist:
javax.persistence.Table.indexes()[Ljavax/persistence/Index;
The method's class, javax.persistence.Table, is available from the following locations:
jar:file:/Users/arianehine/IdeaProjects/SHProject/config-backend-spring/lib/javax.persistence.jar!/javax/persistence/Table.class
jar:file:/Users/arianehine/.m2/repository/jakarta/persistence/jakarta.persistence-api/2.2.3/jakarta.persistence-api-2.2.3.jar!/javax/persistence/Table.class
jar:file:/Users/arianehine/.m2/repository/javax/persistence/javax.persistence-api/2.2/javax.persistence-api-2.2.jar!/javax/persistence/Table.class
It was loaded from the following location:
file:/Users/arianehine/IdeaProjects/SHProject/config-backend-spring/lib/javax.persistence.jar
Action:
Correct the classpath of your application so that it contains a single, compatible version of javax.persistence.Table
Process finished with exit code 0
Я уже много чего пробовал в Интернете, но я чувствую, что сейчас просто иду по кругу.
