If you would like us to spend some time helping you to diagnose the problem, please spend some time describing it.

Judging from the code, you're trying to use QuerydslPredicateExecutor. Querydsl is not supported for R2DBC repositories.

[sheiy]

thanks for you reply.
I think the code has already expressed what I mean. In fact, you do understand it, so I didn't use more words to describe it.
If Querydsl is not supported for R2DBC repositories, why it in the document https://docs.spring.io/spring-data/r2dbc/docs/1.1.0.RC1/reference/html/#core.extensions.querydsl? Did I miss anything? It confused me.

That's the way Spring Data documentation is structured. The begging on the common section explains all possible Spring Data repository features while mentioning that not all Spring Data modules support everything. That being said, closing this ticket without further changes.
