Swagger Codegen OneOf 生成不正确

Question

我正在使用 OpenAPISpec 文档生成 JavaClient。我使用swagger-codegen 3.0 来生成代码。 OpenAPISpec 版本是3.0.1。

以下是我遇到的问题的 OpenAPI sn-p：

"RequestWithInsuranceInfo": {
        "type": "object",
        "description": "This request schema will produce a response containing an out of pocket estimate for the given service using the patient's insurance information.",
        "additionalProperties": false,
        "properties": {
          "insuranceInfo": {
            "$ref": "#/components/schemas/InsuranceInfo"
          },
          "service": {
            "type": "object",
            "additionalProperties": false,
            "description": "Schema to use when the patient's benefit info is not given in the request.",
            "properties": {
              "codes": {
                "type": "array",
                "items": {
                  "$ref": "#/components/schemas/ServiceCode"
                }
              },
              "provider": {
                "$ref": "#/components/schemas/Provider"
              },
              "costs": {
                "$ref": "#/components/schemas/ServiceCosts"
              }
            },
            "required": [
              "codes",
              "provider",
              "costs"
            ]
          }
        }
      },
"InsuranceInfo": {
        "description": "Information about the payer, plan, and members.",
        "additionalProperties": false,
        "oneOf": [
          {
            "type": "object",
            "additionalProperties": false,
            "title": "Option 1: Patient Is Policy Holder",
            "description": "Schema to use when the patient the primary on the insurance plan.",
            "properties": {
              "payer": {
                "$ref": "#/components/schemas/Payer"
              },
              "policyHolderInfo": {
                "$ref": "#/components/schemas/PolicyHolderInfo"
              }
            },
            "required": [
              "payer",
              "policyHolderInfo"
            ]
          },
          {
            "type": "object",
            "additionalProperties": false,
            "title": "Option 2: Patient Is Dependent",
            "description": "Schema to use when the patient is a dependent on the insurance plan.",
            "properties": {
              "payer": {
                "$ref": "#/components/schemas/Payer"
              },
              "dependentMemberInfo": {
                "$ref": "#/components/schemas/DependentMemberInfo"
              },
              "policyHolderInfo": {
                "$ref": "#/components/schemas/PolicyHolderInfo"
              }
            },
            "required": [
              "payer",
              "dependentMemberInfo",
              "policyHolderInfo"
            ]
          }
        ]
      },

下面是生成的代码：

public class InsuranceInfo implements OneOfInsuranceInfo {

  @Override
  public boolean equals(java.lang.Object o) {..}

  @Override
  public int hashCode() {..}

  @Override
  public String toString() {..}

  private String toIndentedString(java.lang.Object o) {..}
}


public interface OneOfInsuranceInfo {

}


public class RequestWithInsuranceInfo implements OneOfRequest {
  @SerializedName("insuranceInfo")
  private InsuranceInfo insuranceInfo = null;

  @SerializedName("service")
  private RequestWithInsuranceInfoService service = null;
 ..

}

public class Payer {
  @SerializedName("id")
  private String id = null;
  
  ..
}

public class PolicyHolderInfo {
  @SerializedName("memberId")
  private String memberId = null;

  @SerializedName("firstName")
  private String firstName = null;

  @SerializedName("lastName")
  private String lastName = null;

  @SerializedName("dateOfBirth")
  private LocalDate dateOfBirth = null;

  ..
}

public class DependentMemberInfo {
  @SerializedName("memberId")
  private String memberId = null;

  @SerializedName("firstName")
  private String firstName = null;

  @SerializedName("lastName")
  private String lastName = null;

  @SerializedName("dateOfBirth")
  private LocalDate dateOfBirth = null;

  ..

}

如图所示，InsuranceInfo 对象实现了OneOfInsuranceInfo 接口，但没有变量。 Payer、PolicyHolderInfo 和dependentMemberInfo 类已生成，但它们无论如何都没有链接到InsuranceInfo 类。如何填充 InsuranceInfo 类？

Answer 1

问题可能是 InsuranceInfo 架构

"InsuranceInfo": {
  "description": "Information about the payer, plan, and members.",

  "additionalProperties": false,
  "oneOf": [
    { ... },
    { ... }
  ]
}

实际上禁止所有属性。这是因为additionalProperties: false 只知道直接定义在它旁边的properties 和has no visibility 到oneOf 子模式中。

要解决此问题，您可以在不使用 oneOf 的情况下重写 InsuranceInfo 架构，如下所示。此架构基本上是原始架构的“选项 2”，除了 dependentMemberInfo 属性被定义为可选。

"InsuranceInfo": {
  "description": "Information about the payer, plan, and members.",
  "additionalProperties": false,
  "type": "object",
  "required": [
    "payer",
    "policyHolderInfo"
  ],
  "properties": {
    "payer": {
      "$ref": "#/components/schemas/Payer"
    },
    "dependentMemberInfo": {
      "$ref": "#/components/schemas/DependentMemberInfo"
    },
    "policyHolderInfo": {
      "$ref": "#/components/schemas/PolicyHolderInfo"
    }
  }
}
