Hibernate зависает при экспорте схемы

1 голос
/ 16 марта 2011

Мой модульный тест использует HSQLDB в оперативной памяти с созданной Hibernate схемой на лету. Теперь в конкретном случае (пока не подробно, связанном с отношением @ManyToMany) экспорт схемы зависает. Когда это конкретное отношение не используется в тестовом примере, оно не зависает.

Ведение журнала при зависании:

Отдельный фрагмент отображения в BookInfo (в Scala, но может читаться как Java): 

  @S.ManyToMany(
    fetch = FetchType.LAZY,
    cascade = Array(CascadeType.PERSIST)
  )
  @S.JoinTable(
    name = "BookInfo_Author",
    joinColumns = Array(new S.JoinColumn(name = "bookInfo")),
    inverseJoinColumns = Array(new S.JoinColumn(name = "author"))
  )
  @BeanProperty
  var authors: java.util.Set[Author] = new java.util.HashSet[Author]()

Тестовый пример создает объект BookInfo, устанавливает автора и сохраняет его с помощью метода persist шаблона Spring Hibernate. Наконец, при закрытии сеанса экспорт схемы зависает.

Есть идеи?

Причиной для меня было то, что я не откатил неудачную транзакцию (после исключения), которая, вероятно, оставила некоторые таблицы в заблокированном состоянии. Обеспечение отката решило проблему для меня.

PS: я использовал базу данных MySQL

Пожалуйста, используйте HSQLDB 2.1 вместе с Hibernate 3.6 или новее, чтобы избежать известных проблем совместимости.Я не знаю, если это решит проблему, хотя.

Для меня это также зависало после печати следующей строки во время модульного теста: 

[INFO|org.hibernate.tool.hbm2ddl.SchemaExport|JCLLoggerAdapter] exporting generated schema to database

У меня было несколько тестовых классов.Поэтому в каждом из тестовых классов я создавал новый объект SessionFactory в статическом методе @BeforeClass, как показано ниже, с использованием AnnotationConfiguration.

public class MyClassTest{    
    private static SessionFactory testSessionFactory = null;

    @BeforeClass    
    public static void initialize() {
        Properties testHibernateProperties = new Properties();
        // set testHibernateProperties
        AnnotationConfiguration configuration = new AnnotationConfiguration().addProperties(testHibernateProperties)
                        .addAnnotatedClass(someAnnotatedClass.class);
        testSessionFactory = configuration.buildSessionFactory();
    }

    // Adding this in each test class creating SessionFactory solved the problem
    @AfterClass
    public static void destroy(){
        testSessionFactory.close();
    }
}

Я не закрывал sessionFactory явно ни в одном тестовом классе.Для меня это решило проблему, когда я начал закрывать sessionFactory явно, как показано в методе destroy.
