"@Transactional(readonly=true, propagation=Propagation.REQUIRED)" Is it possible to set it up?

Currently, I am using the postgresql master/slave environment.The development environment is spring boot.

I'd like to organize the transaction as follows:

TX Begin    @Transactional (readOnly=false)      insert into t1 values(1);   @Transactional (readOnly=true, propagation=Propagation.NESTED) or    @Transactional (readOnly=true, propagation=Propagation.REQUIRED)      select * from t1 where c1=1;    commit;TX End;

In the above case, is it possible to read the records from the Replica (Slave) server without having to commit after INSERT?

Thanks.
