UnuniqueObjectException-具有相同标识符值的不同对象已与会话关联

hibernate java

ecdhe · 技术社区 · 6 年前

尝试从会话中删除Address对象时,出现此异常 org.hibernate.NonUniqueObjectException: a different object with the same identifier value was already associated with the session .

  //The relation between a User and an Address is Ont-To-One with no cascade at any of the joining columns (Address#user and User#address)
    Address address = user.getAddress();
    if(address!=null){
        usr.setAddress(null);    
        //I have tried to merge before/after unbinding the object from the session, neither of both worked
        //addressDao.merge(addressByAddress);
        addressDao.unbindObjectFromSession(addressByAddress);               
        addressDao.remove(addressByAddress);         
    }

地址daoimpl.java

public class AddressDaoImpl extends GenericDaoImpl<Address> implements AddressDao {
    private static org.apache.log4j.Logger log = Logger.getLogger(AddressDaoImpl.class);
    public AddressDaoImpl() {
        super(Address.class);
    }

    //omitted source code
}

GenericDaoImpl.java类

public class GenericDaoImpl<T extends IdInterface> extends HibernateDaoSupport implements GenericDao<T> {
    private static final Logger LOG = LoggerFactory.getLogger(GenericDaoImpl.class);
    private final Class<T> type;
    public GenericDaoImpl(final Class<T> type) {
        this.type = type;
    }

    @Override
        public boolean remove(final T removeObject) {
        getHibernateTemplate().delete(removeObject);
        LOG.trace("An entity of type \"{}\" has been deleted from db. ID: {}", type.getSimpleName(), removeObject.getId());
        return true;
        }

    @Override

    public void unbindObjectFromSession(final Object unbindObject) {
        getSession().evict(unbindObject);
        getSession().flush();
        LOG.trace("An entity of type \"{}\" has been unbound from session. ID: {}", type.getSimpleName(), unbindObject.getClass().getSimpleName());

        }

    @Override
    public void merge(final Object obj) {
        log.debug("merge("+address.getId()+")");
        this.getHibernateTemplate().merge(obj);                
    }

你要完成的工作应该是这样的:

// Start a spring transaction that wraps the operation
@Transactional
public void removeAddressById(Long addressId) {
  // I'm just locating the address from the database based on some provided id.
  final Address address = addressDao.findById( addressId );
  // break the association between the associated User and Address.
  address.getUser().setAddress( null );
  address.setUser( null );
  // Update the user and remove the address
  // If address owns the one-to-one association, then the merge is unnecessary
  getHibernateTemplate().merge( user );
  getHibernateTemplate().delete( address );
}

由于您正试图删除/删除实体,因此持久性提供程序将自动从持久性上下文中逐出该对象。
