英文:
Mask entity field before sending to UI from Spring Rest
问题
我们正在使用Spring Rest，该接口将课程实体对象返回给用户界面。用户界面会修改课程对象并更新它。在这里，我们不希望向修改课程对象的用户显示URL字段。因此，我想对该字段进行屏蔽处理。请问您可以提供修改的最佳方法吗？
英文:
we are using spring rest which returns course entity object to UI. UI modify course object and update course object. here we don't want to show the URL field to a user who is modifying that course object. so I want to mask that single field. can you please suggest the best way to modify that

-
从数据库中只获取相关数据 - 查看Spring Data REST的
Projection功能。它允许获取实体数据的子集并自动公开它。 -
抑制实体数据序列化 - 如果您需要获取实体数据但从不公开它，可以在字段上使用简单的
@JsonIgnore注解。
英文:
-
Bring only relevant data from database - Check Spring Data REST
Projectionfacility. It allows bringing a subset of entity data and automatically expose it. -
Suppress entity data serialization - If you need to bring entity data but never expose it, a simple
@JsonIgnoreannotation on field may be used.

最终，我们实施了这个方案。与其进行掩盖，我们决定不通过 @JsonIgnore 将该字段发送到 UI。但是在更新对象时出现了问题。所以只对 getter 方法添加了 @jsonIgnore，然后对该字段添加了 @JsonProperty(access = Access.WRITE_ONLY)。因此，与其掩盖，我们选择不向 UI 发送该字段，并允许通过 @jsonIgnore 的定制来进行写入。
英文:
Eventually, we implemented this. instead of masking, we decided don't want to send that field to UI by @JsonIgnore. But that failed while updating the object. so added @jsonIgnore only got getter method and add @JsonProperty(access = Access.WRITE_ONLY) to the field. so instead of masking we are not sending the field to UI and allow the field to write by customization of @jsonIgnore
