没有生成数组 List<ComplexType> 而是 List<Object>

Question

我有一个复杂的模式，我正在为其生成 POJO。但是，我注意到虽然它们被标记为 object 类型，但并未为类型 array 内的项目生成复杂类型。我用非常简单的模式做了一个快速测试

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "javaType": "com.walmart.services.tesseract.service.request.models.inkiru.PaymentHead",
  "properties": {
    "payments": {
      "type": "array",
      "items": [
        {
          "type": "object",
          "properties": {
            "paymentHandle": {
              "type": "string"
            },
            "txndate ": {
              "type": "string"
            },
            "ordernumber": {
              "type": "string"
            },
            "stgOrderNumber": {
              "type": "string"
            }
          }
        }
      ]
    }
  }
}

这会生成以下 POJO

@JsonInclude(JsonInclude.Include.NON_NULL)
@JsonPropertyOrder({
    "payments"
})
public class PaymentHead {

    @JsonProperty("payments")
    private List<Object> payments = new ArrayList<Object>();

    @JsonProperty("payments")
    public List<Object> getPayments() {
        return payments;
    }

    @JsonProperty("payments")
    public void setPayments(List<Object> payments) {
        this.payments = payments;
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(PaymentHead.class.getName()).append('@').append(Integer.toHexString(System.identityHashCode(this))).append('[');
        sb.append("payments");
        sb.append('=');
        sb.append(((this.payments == null)?"<null>":this.payments));
        sb.append(',');
        if (sb.charAt((sb.length()- 1)) == ',') {
            sb.setCharAt((sb.length()- 1), ']');
        } else {
            sb.append(']');
        }
        return sb.toString();
    }

}

但是，它应该是 complexType，而不是 Object。不是吗？我错过了什么吗？

正确的架构应该是。请注意，items 是模式中的对象，而不是数组。

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "type": "object",
  "javaType": "com.walmart.services.tesseract.service.request.models.inkiru.PaymentHead",
  "properties": {
    "payments": {
      "type": "array",
      "items":
        {
          "type": "object",
          "properties": {
            "paymentHandle": {
              "type": "string"
            },
            "txndate ": {
              "type": "string"
            },
            "ordernumber": {
              "type": "string"
            },
            "stgOrderNumber": {
              "type": "string"
            }
          }
        }
    }
  }
}
