SqlParameterSource implementation that obtains parameter values from bean properties of a given JavaBean object, from component accessors of a record class, or from raw field access.

This is a more flexible variant of BeanPropertySqlParameterSource, with the limitation that it is not able to enumerate its parameter names.

In terms of its fallback property discovery algorithm, this class is similar to org.springframework.validation.SimpleErrors which is also just used for property retrieval purposes (rather than binding).
