Would it make a difference if database metadata were separated and stored externally (for example, in XML)? If such classes are

Mybatis Generator: What's the best way to separate out “auto generated” and “hand edited files”

阅读更多关于 Mybatis Generator: What's the best way to separate out “auto generated” and “hand edited files”

Is there any way to have "best of both worlds", i.e use auto generation as as well as "custom code". How do you separate out and structure the "hand edited files" and
