Java / Spring捕获异常/记录和更新状态

Question

Lets say that from a spring service, i want to invoke through a client an external system, if that invocation fails (throws unchecked exception) i want to log it, update order status in DB and rethrow the exception for the transaction to be rollbacked...

I know that below sample code is considered to be an anti-pattern but i cannot think of something better to achieve this...any comments pls?

public class Service {

@Autowired(required = true)
private Client client;

@Autowired(required = true)
private DAO d;

@Transactional
@Override
public void register(String id) {

     try{
      client.invoke(id);//throws Client unchecked exception
     }
     catch (ClientException e){
         LOG.error (e);
         d.updateStatus(id,"failed");
         throw e;
      }
 }
}

如果抛出异常只是为了使事务回滚，则最好使用它并调用setRollbackOnly

  TransactionInterceptor.currentTransactionStatus().setRollbackOnly();
