Java Hibernate Spring AnnotationException не отображенный класс

1 голос
/ 02 марта 2012

mvn clean install работает без ошибок, но когда я запускаю tomcat6, я получаю следующую ошибку: Причина: 

org.hibernate.AnnotationException: Use of @OneToMany or @ManyToMany targeting an unmapped class: com.xxx.server.entity.app.App.distributions[com.xxx.server.entity.distribution.Distribution]

Все дерево в конце.

Я искал целый день здесь и в Интернете, но не нашел для меня работающего решения.

Настройка: Я хочу установить связь между многими и многими пользователями Hibernate между двумя классами: App и Distribution:

Distribution.java: 

@Entity
@Table(name = "DISTRIBUTION")
public class Distribution extends xxxEntity {

    @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinTable(name = "APP_DISTRIBUTION", joinColumns = { @JoinColumn(name = "distribution_id") }, inverseJoinColumns = { @JoinColumn(name = "app_id") })
    private Set<App> apps;

    }

App.java: 

@Entity
@Table(name="APP")
public class App extends xxxEntity {

    @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinTable(name = "APP_DISTRIBUTION", joinColumns = { @JoinColumn(name = "app_id") }, inverseJoinColumns = { @JoinColumn(name = "distribution_id") })
    private Set<Distribution> distributions;

Я тоже пробовал это с targetEntity.

сопоставление находится в файле server-persistence.xml:

Еще одна странная вещь: в проекте уже работает реализация ManyToMany, которая прекрасно работает: 

public class Info extends xxxEntity {
    @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinTable(name = "USER_INFO", joinColumns = { @JoinColumn(name = "info_id") }, inverseJoinColumns = { @JoinColumn(name = "user_id") })
    private Set<User> users;

public class User extends xxxEntity {
    @ManyToMany(cascade = CascadeType.ALL, fetch = FetchType.LAZY)
    @JoinTable(name = "USER_INFO", joinColumns = { @JoinColumn(name = "user_id") }, inverseJoinColumns = { @JoinColumn(name = "info_id") })
    private Set<Info> infos;

Я написал два теста, и они прошли через !!! 

public class DistributionTest extends BaseDaoTest {
    @Test
    @Transactional
    @Rollback(true)
    public void testDistribution() {
        // Test saving and loading Distribution
        Distribution distribution = DomainCreator.createDistribution("Fedora", "16.01");
        this.distributionDao.save(distribution); 
        assertEquals(distribution, this.distributionDao.findByName("Fedora"));

        // test loading set of distributions
        App app = appDao.findById("a1");
        Set<Distribution> distros = app.getDistributions();
        assertEquals(3, distros.size());
   }
}

public class AppDaoTest extends BaseDaoTest   {
@Test
@Transactional
@Rollback(true)
public void getAppsByDistribution() {
    Distribution distribution = distributionDao.findById("d1");
    Set<App> apps = distribution.getApps();
    assertEquals(4, apps.size());
}
}

Итак, я полагаю, что это проблема с Tomcat6?

То, что я также сделал: удаление всего в каталоге развертывания Tomcat при публикации, но все та же ошибка.

У кого-нибудь есть идея?

После того, как я написал тесты, которые прошли. У меня была идея, что мой местный tomcat6 делает что-то не так. Поэтому я развернул свои изменения на другом сервере, и там это сработало! Извините, что беспокою вас неправильным вопросом.

Большое спасибо всем за помощь.

Приветствия

Проверьте пример 3 на http://docs.oracle.com/javaee/5/api/javax/persistence/ManyToMany.html. Таким образом, отображение приложения должно быть таким, 

@Entity
@Table(name="APP")
public class App extends xxxEntity {

    @ManyToMany(mappedBy="apps")
    private Set<Distribution> distributions;

Также проверьте, настроены ли joinColumns и inverseJoinColumns в соответствии с примером.
