问一个关于 graphQL 的 schema 写法问题

JavaBean 是这样的

Class User{
	private Long id;
	private Integer active;
	private String sn;
	private String name;
	private String kind;
	private String gender;
	private Integer age;
	private String remark;
	private Object data;
    }

Object data 中是一个 JsonObject schema 文件要怎么写才能让 User 类映射上去 想要的显示结果是这样的

{
  "data": {
    "userById": {
      "id": 1,
      "active": 1,
      "sn": "kg",
      "name": "库管",
      "age": null
      ...
      "data": {
      	"role": "aa"
        "phone": "1111111"
        ...
      }
    }
  }
}
