Java 在Spring4MVC+；中执行更新/删除查询时出错；冬眠4+；MySQL+；专家

我有一个应用程序（Spring4MVC+Hibernate4+MySQL+Maven集成示例使用注释），使用基于注释的配置将Spring与Hibernate集成，但我在更新对象时出错

这里是我的控制器：

@Controller
@RequestMapping("/")
public class AppController {

    @Autowired
    DeviceService deviceService;

    @Autowired
    DeviceEventService deviceEventService;

    @Autowired
    ApplicationService applicationService;

    @Autowired
    MessageSource messageSource;




    /*
     * This method will list all existing devices.
     */
    @RequestMapping(value = { "/", "/list" }, method = RequestMethod.GET)
    public String listDevices(ModelMap model) {


        Device device = new Device("E506");
        DeviceEvent deviceEvent = new DeviceEvent(device);
        deviceEvent.setCoordinates(deviceEvent.new Coordinates(Double.MIN_VALUE, Double.MAX_VALUE));
        deviceEvent.setMessage("message");
        deviceEvent.setReceived(new Date().getTime());

        deviceEventService.save(deviceEvent);       

        model.addAttribute("devices", deviceService.findAll());
        return "alldevices";
    }

服务：

@Service("deviceEventService")
@Transactional
public class DeviceEventServiceImpl implements DeviceEventService {

    @Autowired
    private DeviceEventDao dao;


    public void save(DeviceEvent deviceEvent) {
        dao.save(deviceEvent);      
    }

}

道：

@Repository("deviceEventDao")
public class DeviceEventDaoImpl extends AbstractDao<Integer, DeviceEvent> implements DeviceEventDao {

    @PersistenceContext
    private EntityManager manager;

    public void save(DeviceEvent deviceEvent) {

        manager.createNamedQuery("insertDeviveEvent", DeviceEvent.class)
                .setParameter(1, deviceEvent.getDevice().getKey())
                .setParameter(2, deviceEvent.getCoordinates().getLat())
                .setParameter(3, deviceEvent.getCoordinates().getLng()).setParameter(4, deviceEvent.getMessage())
                .setParameter(5, deviceEvent.getReceived()).executeUpdate();

    }
}

这里是错误：

首先，为什么要使用insert查询，而不是简单地让hibernate为您这样做？只要持久化实体，第二步就是使用JPA，但是使用的是一个普通的Hibernate事务管理器，它不起作用。请改用

JpaTransactionManager
