希望可以支持一下JSONQuery("key").NotEquals(...)

我尝试着复制JSONQuery代码自己修改NotEquals，发现gorm框架里面有各种各样的类型限制，导致我没法直接设计自己的NotEquals
所以希望架构能支持JSONQuery.NotEquals, 或者说至少支持我自定义实现JSONQuery等部类型的相关Condition接口

func exprToCondition(exprs ...clause.Expression) []Condition {
	conds := make([]Condition, 0, len(exprs))
	for _, e := range exprs {
		switch e := e.(type) {
		case *datatypes.JSONQueryExpression, *datatypes.JSONOverlapsExpression:
			conds = append(conds, &condContainer{value: e})
		default:
			conds = append(conds, &condContainer{err: fmt.Errorf("unsupported Expression %T to converted to Condition", e)})
		}
	}
	return conds
}


func condToExpression(conds []Condition) ([]clause.Expression, error) {
	if len(conds) == 0 {
		return nil, nil
	}
	exprs := make([]clause.Expression, 0, len(conds))
	for _, cond := range conds {
		if cond == nil {
			continue
		}
		if err := cond.CondError(); err != nil {
			return nil, err
		}

		switch cond.(type) {
		case *condContainer, field.Expr, SubQuery:
		default:
			return nil, fmt.Errorf("unsupported condition: %+v", cond)
		}

		switch e := cond.BeCond().(type) {
		case []clause.Expression:
			exprs = append(exprs, e...)
		case clause.Expression:
			exprs = append(exprs, e)
		}
	}
	return exprs, nil
}
