Hibernate ошибка отношение не существует

I am having some problems trying to work with PostgreSQL and Hibernate, more specifically, the issue mentioned in the title. I’ve been searching the net for a few hours now but none of the found solutions worked for me.

I am using Eclipse Java EE IDE for Web Developers. Build id: 20090920-1017 with HibernateTools, Hibernate 3, PostgreSQL 8.4.3 on Ubuntu 9.10.

Here are the relevant files:

Message.class

package hello;

        public class Message {
         private Long id;
         private String text;

         public Message() {
         }

         public Long getId() {
          return id;
         }

         public void setId(Long id) {
          this.id = id;
         }

         public String getText() {
          return text;
         }

         public void setText(String text) {
          this.text = text;
         }
        }

public class App {

 public static void main(String[] args) {

    .buildSessionFactory();

  Message message = new Message();
  message.setText("Hello Cruel World");
  message.setId(2L);

  Session session = null;
  Transaction transaction = null;
  try {

   session.save(message);
  } catch (Exception e) {

  } finally {

    if (transaction != null)
     transaction.commit();
    session.flush();
    session.close();
   }

  }
 }
}

PostgreSQL log file

2010-04-28 23:13:55 EEST LOG:  execute S_1: BEGIN
2010-04-28 23:13:55 EEST ERROR:  relation "public.messages" does not exist at character 13
2010-04-28 23:13:55 EEST STATEMENT:  insert into public.messages (messagetext, id) values ($1, $2)
2010-04-28 23:13:55 EEST LOG:  unexpected EOF on client connection

If I copy/paste the query into the postgre command line and put the values in and ; after it, it works.

Everything is lowercase, so I don’t think that it’s that issue.

If I switch to MySQL, the same code same project (I only change driver,URL, authentication), it works.

In Eclipse Datasource Explorer, I can ping the DB and it succeeds. Weird thing is that I can’t see the tables from there either. It expands the public schema but it doesn’t expand the tables. Could it be some permission issue?

Thanks!

Пытаюсь разобраться со связкой spring jpa + hibernate. Исходные данные:
— БД — postgresql 10
— Для генерации id cущности использую sequence в БД
— не SpringBoot — разворачиваю war в Tomcat

Сущность:

@Entity
@Table(name = "category")
public class Category {

    @Id
    @Column(name = "category_id")
    @GeneratedValue(strategy = GenerationType.IDENTITY)
    private int id;
//остальные члены класса
}

Репозиторий для работы с БД:

@Repository
public interface CategoryRepository extends JpaRepository<Category, Integer> {
}

Проблема — при попытке добавить запись в БД получаю ошибку:
org.postgresql.util.PSQLException: ОШИБКА: отношение «category_category_id_seq» не существует

Т.е. hibernate вместо того, чтобы опираться на на sequence в БД при добавлении записи (он должен это делать в соответствии с аннотацией @GeneratedValue(strategy = GenerationType.IDENTITY)) пытается вычислить id из таблицы category_category_id_seq, которой нет.

При этом получение записей из БД или обновление существующих работает корректно. Работу sequence проверял ручным добавлением записи в БД.

upd:
Порылся в исходниках hibernate и в диалекте для своей БД нашел что для вычисления идентификатора используется запрос вида select currval(‘» + table + ‘_’ + column + «_seq’), т.е. идет обращение именно к sequence, а она у меня называется не так.
category_category_id_seq

Фреймворк ssh, используемый проектом; база данных проекта была перенесена с mysql на pgsql, и проблема отсутствия последовательности гибернации возникла после миграции базы данных.

С точки зрения связанной информации, класс сущности в Hibernate использует собственный метод для генерации первичных ключей. Native определяется Hibernate на основе используемой базы данных и использует один из следующих методов: identity, hilo и sequence в качестве метода генерации первичного ключа. .

MySQL использует автоинкремент в качестве первичного ключа, тогда как базы данных Oracle, pgsql и DB2 могут не иметь подобных типов автоинкремента, поэтому для его поддержки необходима последовательность с именем hibernate_sequence. То есть вам нужно создать его вручную после миграции.

нота: В pgsql последовательность создается в шаблоне, в одном шаблоне она есть, а другие шаблоны нужно создавать заново (я такой).

Оператор последовательности hibernate_sequence:

create sequence HIBERNATE_SEQUENCE
minvalue 100000
maxvalue 9999999999999999
start with 100060
increment by 1
cache 20;

После создания этой модели эта проблема была решена.

Примечания: Значение атрибута для создания последовательности можно найти в следующем блоге.

Учебник по синтаксису PostgreSQL-9.6.8 для создания последовательностей, изменения последовательностей и удаления последовательностей

Я выполняю пакетное обновление hibernate jpa и даю мне следующую ошибку

2015-04-21 15:53:51,907 WARN  [org.hibernate.engine.jdbc.spi.SqlExceptionHelper] (Thread-283 (HornetQ-client-global-threads-462057890)) SQL Error: 0, SQLState: 42P01

Я использую базу данных postgres, и мой идентификатор сгенерирован автоматически

  @Id
@SequenceGenerator(name="seq-gen",sequenceName="MY_SEQ_GEN"initialValue=205, allocationSize=12)
@GeneratedValue(strategy= GenerationType.SEQUENCE, generator="seq-gen")
@Column(name=""ID"",unique=true,nullable=false)
private int id;

Это мой фрагмент кода вставки пакета

getEm().getTransaction().begin();
System.out.println("transaction started--------------");
try {   
    for (Receipt ReceiptEntity : arrReceiptEntity) {
            getEm().persist(ReceiptEntity);
    }
    getEm().getTransaction().commit();
    System.out.println("commited");
} catch (Exception exception) {
    System.out.println("error----------------------------------------------------------------------");
    if(getEm().getTransaction().isActive())
        getEm().getTransaction().rollback();
    LOG.error(exception);
} finally {
    getEm().flush();
    getEm().clear();
    getEm().close();
}

Я добавил следующее свойство в persistence.xml

         <property name="hibernate.id.new_generator_mappings" value="true"/>

Пожалуйста, предложите, что я делаю неправильно.
