I write such an interface and return gin.H{} Screenshot below：

but this struct is nil . I made a mistake myself, I hope to get your answer

Demo

@success 200 {object} jsonresult.JSONResult{data=nil} "desc"

data should be nil, nil will be json null

but this feature does not work

OAS defines the data types, not values.

type JSONResult struct {
    Code    int          `json:"code" `
    Message string       `json:"message"`
    Data    interface{}  `json:"data"`
}

The annotation @success 200 {object} jsonresult.JSONResult{data=proto.Order} "desc" will define the type for JSONResult.Data as been a proto.Order. The OAS model definition will look like this:

type JSONResult struct {
    Code    int          `json:"code" `
    Message string       `json:"message"`
    Data    proto.Order  `json:"data"`
}
