javax.persistence.PersistenceException: org.hibernate.exception.SQLGrammarException: не удалось выполнить запрос с помощью heroku postgressql

Question

Я пытаюсь использовать базу данных в своем приложении, но продолжаю получать эту ошибку. Его работая на локальном компьютере, когда я загрузил его в герою, он продолжает давать эту ошибку. Я провел весь день, чтобы получить какое-либо решение, но не успел. Поэтому, если кто-нибудь может помочь мне с этим, это будет очень полезно.

Вы также можете найти его на github. : Github

Answer 1

Мы также столкнулись с той же проблемой. Мы создали в xml и @GeneratedValue столбец id. Разрешение снимает аннотацию @GeneratedValue и ставит значение id вручную, также по умолчанию jpa занимает длинное значение, например, 1l.

Чтобы сделать автогенерацию, следуйте следующему правилу.

Проблема вокруг связанной JPA автогенерируемой Id решена, как показано ниже:

Измените класс Person.java моделей имеют следующие аннотации для атрибута Id:

@Id 
@TableGenerator(name="TABLE_GEN",table="T_GENERATOR",pkColumnName="GEN_KEY",pkColumnValue="TEST",valueColumnName="GEN_VALUE",initialValue=1,allocationSize=1) 
@GeneratedValue(strategy=GenerationType.TABLE, generator="TABLE_GEN") 
public Long Id; 

Это создаст таблицу в схема mysql, называемая T_GNERATOR, которая будет отслеживать следующее значение для Id и JPA по сравнению с hibernate, знает, как получить это значение. Предполагается, что начальное значение для Id равно 1, и оно увеличивается на 1 при каждой новой вставке в него, как очевидно из атрибутов аннотации.

Answer 2

У меня была такая же проблема на JavaDB/Дерби. Решение заключалось в использовании явного имени таблицы! = "User": @Table (name = "my_user_table"). Но он также должен быть зафиксирован с явной схемой, потому что «пользователь» представляет собой системную таблицу

Answer 3

В моем случае решение было довольно простым. Столбец, который был зарегистрирован в MySQL, не существует в модели. Поэтому я получил указанное сообщение об ошибке. Потребовалось немного времени для устранения неполадок.
