AST 可以用 ast.Inspect 去遍历，是不是更好一点
像这样

ast.Inspect(node, func(n ast.Node) bool {
				if v, ok := n.(*ast.TypeSpec); ok {
					if !gstr.Contains(v.Name.Name, "Req") {
						return false
					}

					if _, ok := v.Type.(*ast.StructType); !ok {
						return false
					}

					if err := printer.Fprint(&buf, fileSet, v.Type); err != nil {
						return nil, err
					}

					structsInfo[v.Name.Name] = buf.String()
					return false
				}
				return true
			})

AST can be traversed using ast.Inspect. Isn’t it better?
like this

ast.Inspect(node, func(n ast.Node) bool {
if v, ok := n.(*ast.TypeSpec); ok {
if !gstr.Contains(v.Name.Name, "Req") {
return false
}

if _, ok := v.Type.(*ast.StructType); !ok {
return false
}

if err := printer.Fprint(&buf, fileSet, v.Type); err != nil {
return nil, err
}

structsInfo[v.Name.Name] = buf.String()
return false
}
return true
})

@oldme-git It is awesome!

@oldme-git There's another important improvement: adding unit testing case for command gen ctrl. Without a unit testing case, it is hard to validate this pr working as expect or not. There's similar reference codes https://github.com/gogf/gf/blob/master/cmd/gf/internal/cmd/cmd_gen_dao_test.go

@whileW 我觉得使用for循环比Inspect更加的清晰灵活，而且GetStructs()是封装的方法，不能把"Req"直接拿进来判断

@whileW I think using a for loop is clearer and more flexible than Inspect, and GetStructs() is an encapsulated method, and "Req" cannot be directly used for judgment.

好吧

All right

@gqcn 强哥，你看一下geo ctrl的单测

@gqcn Brother Qiang, take a look at the single test of geo ctrl
