Always use hibernate, recently because it is necessary to add new features to an old system (a movie website) (mobile phone monthly payment), this piece of database lasting layer is really awkward, I don't know how to map it, I naturally I think of it. Ibatis, after two days of research attempts to map a few needed entities and databases, and spent a Test Case in the evening, debugging, but also have a sense of accomplishment, huh, huh.
