JSON中的Olingo 2 OData JPA深度插入

Question

With cars-jpa-archetype example, I am able to perform deep insert (Car and Driver) in XML but not JSON. With my JSON 1 or 2 at below, only Car is inserted and Driver is null. Any one can shed light on my JSON inputs? Have no issue with JSON input if I use Olingo annotations (@EdmEntityType etc).

Sorry for cross post here as no response from the Olingo forum.

似乎在他们的Jira上发布了相同的问题，但现在应该已经解决： https : //issues.apache.org/jira/browse/OLINGO-515
