[gogf/gf][BUG]GF 2.1.* 版本，结构化路由，control使用结构体包含内嵌结构体字段会导致swagger出问题

api使用的结构体

// MentalAnswerReq is the request struct for mental.Answer
type MentalAnswerReq struct {
    g.Meta `path:"/answer" tags:"MentalSrv" method:"post" summary:"问题回答请求结构体"`
    model.MentalAnswerInput
}

// MentalAnswerInput 问题回答请求结构体
type MentalAnswerInput struct {
    ScaleId int `v:"required" json:"scale_id"`
    Answers []struct {
        QuestionId int    `v:"required" json:"question_id"`
        OptionId   string `v:"required" json:"option_id"`
    }
}

control代码

func (c *cMental) Answer(ctx context.Context, req *api.MentalAnswerReq) (res *api.MentalAnswerRes, err error) {
    res = &api.MentalAnswerRes{}
    res.MentalAnswerOutput, err = service.Mental().Answer(ctx, req.MentalAnswerInput)
    return
}

自动生成swagger会失败

结构体定义改成如下方式就没有问题了

// Answer 用于提交答案
type Answer struct {
    QuestionId int    `v:"required" json:"question_id"`
    OptionId   string `v:"required" json:"option_id"`
}

// MentalAnswerInput 问题回答请求结构体
type MentalAnswerInput struct {
    ScaleId int `v:"required" json:"scale_id"`
    Answers []Answer
}

@Tiller-Mu 请提供可复现该问题的最小可运行代码。

我也遇到了，你直接把所有结构体全部拆出去，单独命名，再引入就可以了

kureCC

是的，目前是这样做的。

Tiller-Mu

我也遇到了，现在的临时方法，就是拆结构体，但是有些结构体，是多层嵌套，拆分结构体导致代码很凌乱

@Tiller-Mu @HyunsuQT @kureCC 不好意思各位朋友，请试试最新的版本哈，这个我之前已经修复了。如果仍旧有问题，请重开issue。
