Lifecycle CDI Event

[hantsy]

Like the JPA event listener and do side effect by annotations @Save, @Merge, etc(till now I do not know well about the purpose of these annotations).

Spring Data provides a collection of XXXCallback when converting/saving/updating/delete an entity object.

In Jakarta Data, we can introduce CDI Event instead, make it compatible with all implementation modules.

It is more freely for developers.

It's an appealing idea to use the CDI event bus for this, actually. Definitely worth considering in future.

[But I doubt it's a priority for 1.0.]

I have now received a few requests for this.

I think it would be extremely straightforward to define event types corresponding to our lifecycle operations, e.g. PostUpdateEvent, PreInsertEvent, etc, and specify that a repository should route them to the CDI event bus so that a CDI component can receive them via @Observes.

Reopen this because we will still need to add TCK tests for the function.

I think I'll take a crack at implementing this tonight, make sure it actually works...

Just implemented it. Works beautifully. Love it.
