@ppxb It needs some improvement for command gen service for such feature. It's now using regular expression to implement service go files generating, which is simple and quick. If recognizing nested struct, it might use ast to do so, which might be slow. We need balance the benefits between regular expression and ast plan.

cc @oldme-git you might be interested as we've discussed similar topic recently.
