Willem Jiang updated SCB-1596:
------------------------------
Labels: easyfix (was: )
> Support for defining OmegaContext parameters in @SagaStart and @Compensable
> methods
> -----------------------------------------------------------------------------------
>
> Key: SCB-1596
> URL: https://issues.apache.org/jira/browse/SCB-1596
> Project: Apache ServiceComb
> Issue Type: Improvement
> Components: Saga
> Reporter: Lei Zhang
> Priority: Major
> Labels: easyfix
> Fix For: pack-0.7.0
>
>
> Sometimes users need to get the GlobalTxId or LocalTxId in the business code.
> Currently, practice is to use @Autowired to inject OmegaContext, I suggest
> referring to the way SpringMvc injects HttpServletRequest
>
> Usually, the OmegaContext parameter is declared in a method that is not
> needed. If the user declares the parameter we can pass this value in
> SagaStartAspect or TransactionAspect
>
> The following code shows the usage of the OmegaContext parameters. Both ways
> are OK,
> Practice OmegaContext parameter in methods
> {quote}@SagaStart
> public void booking(OmegaContext omegaContext) {
> omegaContext.globalTxId()
> }
> @Compensable(compensationMethod="cancel")
> public void car(OmegaContext omegaContext, String from, int amount) {
> omegaContext.globalTxId()
> }
> {quote}
>
> Practice @Autowired to inject OmegaContext
