如何将列表发布到Spring Data Rest? [英] How to post a list to Spring Data Rest?

问题描述

我遵循了此示例，它允许发布唯一的Person对象.我想要一个REST服务，可以一次发布Person的集合，例如一次调用一个名为Team的列表/任何集合，其中包含许多Person对象.

我的意思是，我的问题不完全是关于OneToMany关系的问题，在这个关系中，您在REST请求中发送每个人.这个主题很好回答. >

我想利用@RepositoryRestResource或Spring Data Rest的另一个功能来发送Person对象的集合.使用Spring Data Rest可以做到这一点吗?还是应该通过创建一个控制器来解决该问题，接收该列表并解析Team列表以插入每个Person?

我发现了此功能请求，这似乎可以回答如今的Spring Rest Data找不到我想要的东西，但我不确定.

根据我的业务需求，应用程序A将向应用程序B发布订单列表，并且我必须将其保存在数据库中以供将来处理，因此，在阅读了有关Spring Data Rest并制作了一些示例之后，我发现其干净的体系结构令人惊叹并且非常适合我的要求，除了我不知道如何发布列表.

解决方案

好吧，AFAIK使用spring data rest无法做到这一点，只需阅读文档，您会发现，没有提到将列表发布到收集资源.

原因尚不清楚，但有一点-REST本身并没有真正指定您应该如何进行批处理操作. 因此，目前尚不清楚应该如何使用该功能，例如是否应该发布一个列表来收集资源?还是应该导出像/someentity/batch这样的资源，该资源可以批量修补，删除和添加实体?如果要添加列表，应如何返回ID?对于单个POST收集spring-data-rest，在Location标头中返回ID.对于批量添加，无法完成.

这并不能证明spring-data-rest缺少批处理操作.他们应该实施此恕我直言，但至少可以帮助他们理解为什么会遗漏它.

我可以说的是，您总是可以将自己的Controller添加到可以正确处理/someentity/batch的项目中，甚至可以从中创建一个库，以便可以在其他项目中使用它.甚至是fork spring-data-rest并添加此功能.尽管我试图了解它是如何工作的，但到目前为止还是失败了. 但是您可能知道所有这些，对吧?

对此有功能要求.

I followed this example, which allows to post a unique Person object. I want a REST service where I can post a collection of Person at once, e.g. a list/any collection named Team with numerous Person objects in just one call.

I mean, my question is not exactly about the OneToMany relationship, where you send each person in a REST request. This topic is well answered.

I want to send a collection of Person objects taking advantage of @RepositoryRestResource or another feature from Spring Data Rest. Is this possible with Spring Data Rest or should I workaround by creating a controller, receive the list and parse the Team list to insert each Person?

I found this feature request, which seems to answer that nowadays Spring Rest Data is missing what I am looking for, but I am not sure.

In my business requirement, application A will post a list of orders to application B and I have to save it in database for future processing, so, after reading about Spring Data Rest and making some samples, I found its clean architecture amazing and very suitable for my requirement except for the fact that I didn't figure out how to post a list.

解决方案

Well, AFAIK you can't do that with spring data rest, just read the docs and you will see, that there is no mention about posting a list to collection resource.

The reason for this is unclear to me, but for one thing - the REST itself doesn't really specify how you should do batch operations. So it's unclear how one should approach that feature, like should you POST a list to collection resource? Or should you export resource like /someentity/batch that would be able to patch, remove and add entities in one batch? If you will add list how should you return ids? For single POST to collection spring-data-rest return id in Location header. For batch add this cannot be done.

That doesn't justify that spring-data-rest is missing batch operations. They should implement this IMHO, but at least it can help to understand why are they missing it maybe.

What I can say though is that you can always add your own Controller to the project that would handle /someentity/batch properly and you can even probably make a library out of that, so that you can use it in another projects. Or even fork spring-data-rest and add this feature. Although I tried to understand how it works and failed so far. But you probably know all that, right?

There is a feature request for this.
