I assume by "if I change it to add an underscore", you're referring to
the property name inferred by the getter method name, and not the column
name?
Assuming that's true, I'd say that tells us that your @Column annotation
is being completely ignored, as adding an underscore to the property
name would result in the default mapping to the column name.
It's possible that you're using both FIELD and PROPERTY access, which
won't work. Personally, I only use FIELD access.
It's curious that the error message says "does not have any public
fields or setter methods". FIELD access doesn't require the field to be
public. It also specifically refers to "setter" methods, which seems to
imply the annotation should be on the setter, not the getter.
