与 Shopware6 实体定义中的 JSON 字段关联

问：

我有一个以category_ids作为json字段的实体，我想添加一个与类别实体的关联以获取类别的名称 怎么做

这是我的实体定义，这个ManyToManyAssociationField不工作

protected function defineFields(): FieldCollection
    {
        return new FieldCollection([
            (new IdField('id', 'id'))->addFlags(new Required(), new PrimaryKey()),
            (new StringField('group_name','group_name')),
            (new JsonField('category_ids', 'category_ids'))->addFlags(new Required()),
            (new FkField('shipping_method_id', 'shipping_method_id', ShippingMethodDefinition::class))->addFlags(new Required()),
            (new CreatedAtField()),
            (new UpdatedAtField()),
            (new ManyToOneAssociationField('shippingMethod', 'shipping_method_id', ShippingMethodDefinition::class)),
            new ManyToManyAssociationField('category', CategoryDefinition::class, GroupDefinition::class, 'category_ids', 'id'),
        ]);
    }
