------------------------------
Summary: 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
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
{quote}@Autowired OmegaContext omegaContext;
@SagaStart
public void booking() {
omegaContext.globalTxId()
}
@Compensable(compensationMethod="cancel")
public void car(String from, int amount) {
omegaContext.globalTxId()
}
{quote}
