I would like to split my default datasource to 2 different datasources (2 databases). I set my application.conf file:

db {

  common.driver = org.mariadb.jdbc.Driver
  common.username = "root"
  common.password = "123456"
  common.url = "jdbc:mariadb://localhost/common"

  laundry.driver = org.mariadb.jdbc.Driver
  laundry.username = "root"
  laundry.password = "123456"
  laundry.url = "jdbc:mariadb://localhost/laundry"

  #default.logSql=true
}

and I set the ebean models:

ebean.common = ["models.Unit", "models.Building", "models.User"]
ebean.laundry = ["models.Machine", "models.Schedule", "models.Event"]

but I get a fatal error at compile time:

Caused by: com.google.inject.CreationException: Unable to create injector, see the following errors:

2 errors

My Unit.java file looks like:

@javax.persistence.Entity
@Table(name = "units")
public class Unit extends Entity
{
    @Required
    @ManyToOne
    @Column(nullable = false)
    private User owner;

    @Required
    @Column(nullable = false)
    private String name;

    private static Finder<Long,Unit> find = new Finder<Long,Unit>(Unit.class);

    public User getOwner()
    {
        return owner;
    }

    public String getName()
    {
        return name;
    }

    public String getLabel()
    {
        return getName();
    }

    public void setOwner(Long id)
    {
        owner = User.getById(id);
    }

    public void setName(String name)
    {
        this.name = name;
    }

    @Override
    public boolean delete()
    {
        for (User user : User.findByUnit(this))
        {
            user.updateUnit(null);
        }

        return super.delete();
    }

    public static Unit getById(Long id)
    {
        return find.byId(id);
    }

    public static List<Unit> findAll()
    {
        return find.all();
    }
}

And Entity.java is like:

@MappedSuperclass
public abstract class Entity extends Model
{
    @Id
    @Column(nullable = false)
    private long id;

    @Column(nullable = false, updatable = false)
    private LocalDateTime createdAt;

    @Column(nullable = false)
    private LocalDateTime updatedAt;

    public long getId()
    {
        return id;
    }

    public String getLabel()
    {
        return "";
    }

    public LocalDateTime getCreatedAt()
    {
        return createdAt;
    }

    public LocalDateTime getUpdatedAt()
    {
        return updatedAt;
    }

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

    public boolean isPersistent()
    {
        return id > 0;
    }

    @Override
    public void save()
    {
        createdAt();
        super.save();
    }

    public void update()
    {
        updatedAt();
        super.update();
    }

    @Override
    public boolean equals(Object entity)
    {
        if (entity == null) return false;
        if (!(entity instanceof Entity)) return false;
        return id == ((Entity) entity).id;
    }

    @Override
    public int hashCode()
    {
        return (int) id;
    }

    private void createdAt()
    {
        createdAt = updatedAt = LocalDateTime.now();
    }

    private void updatedAt()
    {
        updatedAt = LocalDateTime.now();
    }
}

Should I list all the classes in ebean.XXX = []? Why do I get this error even with the right list?
