@Override
public RibResource toResource(Rib rib) {
    return createResourceWithId(rib.getId(), rib);
}

createResourceWithId（）在内部根据控制器的URL创建自我链接在你的情况下，包含占位符 {idInt} 所以你必须提供一个参数：

createResourceWithId() internally creates a self link based on the controller's URL. In your case that contains the placeholder {idInt} so you would have to provide a parameter for that:

CustomUserDetails user = CurrentUserUtils.getCurrentUser();
return createResourceWithId(rib.getId(), rib, user.getIdInt());

更好的选择是不要调用 createResourceWithId（ ）。只需将现有的所有内容（ instantiateResource（）移至 toResource（）。

The better choice would be not to call createResourceWithId() at all. Just move everything you now have in instantiateResource() to toResource().
