我的代码看起来

try
{
       this.consumerTransactionTemplate.execute(new TransactionCallbackWithoutResult(){
                    @Override
                    protected void doInTransactionWithoutResult(
                            TransactionStatus status)
                    {
                        process();
                    }
                });
  }
  catch(Exception e){
     logger.error("Exception occured " , e);
      //TODO: Exception handling
  }
