Многие из многих, вызывающие MappingException

Question

Я пытаюсь создать многосвязную асоциацию с hibernate4. есть то, что я делаю:

@javax.persistence.Table(name = "devices", schema = "", catalog = "explorer_user") 
@Entity 
public class DevicesEntity { 


    private int id; 

    @javax.persistence.Column(name = "id", nullable = false, insertable = true, updatable = true, length = 10, precision = 0) 
    @Id 
    public int getId() { 
     return id; 
    } 

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

    private Collection<PositionsEntity> positions;//= new HashSet<PositionsEntity>(); 

    @ManyToMany(fetch = FetchType.LAZY, cascade = CascadeType.ALL) 
    @JoinTable(name = "positions_has_devices",  catalog = "explorer_user" , 
      joinColumns = { @JoinColumn(name = "devices_id") }, 
      inverseJoinColumns = { @JoinColumn(name = "positions_id") }) 
    public Collection<PositionsEntity> getPositions(){ 
     return this.positions; 
    } 

    private void setPositions(Collection<PositionsEntity> positions){ 
     this.positions = positions; 
    } 
} 

@javax.persistence.Table(name = "positions", schema = "", catalog = "explorer_user") 
    @Entity 
public class PositionsEntity { 
    private int id; 

    @javax.persistence.Column(name = "id", nullable = false, insertable = true, updatable = true, length = 10, precision = 0) 
    @Id 
    public int getId() { 
     return id; 
    } 

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

    private Collection<DevicesEntity> devices;// = new HashSet<DevicesEntity>(); 

    @ManyToMany(mappedBy = "positions") 
    public Collection<DevicesEntity> getDevices() { 
     return this.devices; 
    } 

    public void setDevices(Collection<DevicesEntity> d) { 
     this.devices = d; 
    } 
} 



@javax.persistence.IdClass(com.printerauditor.jpa.PositionsHasDevicesEntityPK.class) 
@javax.persistence.Table(name = "positions_has_devices", schema = "", catalog = "explorer_user") 
@Entity 
public class PositionsHasDevicesEntity { 
    private int positionsId; 

    @javax.persistence.Column(name = "positions_id", nullable = false, insertable = true, updatable = true, length = 10, precision = 0) 
    @Id 
    public int getPositionsId() { 
     return positionsId; 
    } 

    public void setPositionsId(int positionsId) { 
     this.positionsId = positionsId; 
    } 

    private int devicesId; 

    @javax.persistence.Column(name = "devices_id", nullable = false, insertable = true, updatable = true, length = 10, precision = 0) 
    @Id 
    public int getDevicesId() { 
     return devicesId; 
    } 

    public void setDevicesId(int devicesId) { 
     this.devicesId = devicesId; 
    } 

    private int devicesPrinterLicenceId; 

    @javax.persistence.Column(name = "devices_printer_licence_id", nullable = false,  insertable = true, updatable = true, length = 10, precision = 0) 
    @Id 
    public int getDevicesPrinterLicenceId() { 
     return devicesPrinterLicenceId; 
    } 

    public void setDevicesPrinterLicenceId(int devicesPrinterLicenceId) { 
     this.devicesPrinterLicenceId = devicesPrinterLicenceId; 
    } 
} 

Все таблицы, представленные выше, существует manytomany аннотаций базы на учебники mkyong в. Исключение происходит при развертывании приложения. Белове первопричина:

Hibernate.cfg содержит собственное отображение этих таблиц, IntelliJ признает эти asociation. У вас есть идеи, что может пойти не так?

Answer 1

странная вещь, но преобразование модуля JPA в проект Maven устранило проблему.

Answer 2

попытаться удалить 'schema = "", catalog = "' в @javax.persistence.Table аннотаций класса DevicesEntity

Answer 3

Как ни странно, в моем случае это было достаточно, чтобы удалить schema="myDb" из @Table аннотацию (после @Entity и перед классом заявления). Hibernate здесь немного испортился и, несмотря на отсутствие определения схемы, таблица была создана в правильном db.

Этот пример работает отлично:

@Entity 
@Table(name="foo") //works 
public class Foo { 
... 
@ManyToMany ... //...and here follows all other stuff... 
... 
} 

---

Этот пример не работает:

@Entity 
@Table(name="foo", schema="dbBar") //doesn't work 
public class Foo { 
... 
@ManyToMany ... // ...and here follows all other stuff... 
... 
}
