[DatasourceProxy] How about allowing extending AbstractSlowQueryListener to make it easier to capture and customise actions for slow queries?

[TaeTaeKim]

hello,

I've recently been working with DatasourceProxy to capture slow queries, and I noticed that there is an abstract query listener - I just need to override writeLog or onSlowQuery.

But when I registered MySlowQueryListner as an bean. I get an NPE at runtime. This is because the threshold timeunit required by Thread.schedule() is not configured by the ProxyDatasourceBuilderConfigurer.

So I solved this issue by injecting the datasource proxy property and setting the fields the same as any other SlowQueryListener. This issue asks for feedback on setting the required fields for user registered SlowQueryListener in the ProxyDatasourceBuilderConfigurer.

If this is in line with the direction of the project, can we make a PR for this?
