Spring声明式事务配置异常时回滚的问题

问题：spring 声明式事务，不能回滚多个操作的事务
原因：在service方法里面加了 try{} catch(){},
解决：要把try catch放到action里面

    //Controller
    @Controller
    @RequestMapping("/versionLable")
    public class DeviceVersionLabelController
    {
        @Resource(name = "versLabelService")
        DeviceVersionLabelService versionLabelService;
        
        @RequestMapping("/synchronousdata")
        public ModelAndView test(HttpServletRequest request, 
           HttpServletResponse response)
        {
            
            try
            {
                versionLabelService.updateDeviceVersionLabel(hnInternetId,
                 uploadResponse.getPath());

            }
            catch (Exception e)
            {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            return new ModelAndView("config/hnbversion_list");
        }
        
    }
    
    //Service
    @Service("versLabelService")
    public class DeviceVersionLabelServiceImpl implements      DeviceVersionLabelService
    {
        
        @Resource
        private DeviceVersionLabelDao deviceVerDao;
        
        /**
         * 更新数据版本标签 {@inheritDoc}
         */
        public void updateDeviceVersionLabel(String internetId, String fileName)
        {
            deviceVerDao.deleteSystemInfoLocal(internetId) throws Exception;
            
            deviceVerDao.updateSecLocal(internetId)  throws Exception;  
        }
    }
    
    //Dao
    public interface DeviceVersionLabelDao
    {
        public void deleteSystemInfoLocal(String id)
            throws Exception;
        
        public void updateSecLocal(String id)
            throws Exception;
    }
