如何将对象数组传递给graphql

Question

我正在研究graphql，如何将对象数组传递给graphql类型架构。 例如： 预期输出：

[
  {
    "color": "red",
    "owners": [
       {
          "ownerName":"Rob",
          "ownerOcupation": "teacher"
        }
  }

]

我的模式：

...
type Query {
   allCars:[Car]}

type Car {
color:String
owners: [owner]
 }

type owner {
 ownerName: String
 ownerOcupation: String
 }

汽车实体：

@Column
private String color;
@OneToMany
private List <owner> owners;

owner entity:
@Column
private String ownerName;
@Column
private String ownerOcupation;

它没有按预期显示所有者部分。我应该如何将车主带入车内？
