util/gconv: Fields with the same name in nested structures overwrite values

[wln32]

Go version

1.22

GoFrame version

2.7.3

Can this bug be reproduced with the latest release?

Option Yes

What did you do?

type Rule struct {
    ID int64 `json:"id"`
    Rule []*option.Rule `json:"rule"`
}

type Res1 struct {
    g.Meta
    Rule
}

var err error
var r = &Rule{
    ID: 100,
}
var res = &Res1{}
if err = gconv.Scan(r, res); err != nil {
    fmt.Println("err=", err)
    return
}
for {
    if res.ID == 0 {
        fmt.Println("res.id")
        g.Dump(res)
        fmt.Printf("%+v\n", res)
        time.Sleep(time.Second)
    }
}

What did you see happen?

res.id
{
    ID:   0,
    Rule: {
        ID:   0,
        Rule: [],
    },
}
&{Meta:{} Rule:{ID:0 Rule:[]}}

What did you expect to see?

什么都不输出，赋值正确即可

[wln32]

gconv先把struct转成map

在循环赋值时，如果先拿到的key是id的话，正常赋值成功没有什么问题

第二次是rule时

会走empty.IsNil分支，从而把原值100覆盖掉了

因为Rule结构体和里面的Rule字段重名导致被覆盖

---

gconv first converts struct into map

During the loop assignment, if the key obtained first is the id, there will be no problem with the normal assignment succeeding.

The second time is when rule

Will take the empty.IsNil branch, thereby overwriting the original value of 100
