使用swagger codecen时重复局部变量ContentType

Question

我在使用swagger codegen时遇到了一个问题。我已经从swaggerHub自动下载了swagger表单，然后，我使用swagger代码生成客户端。然而，对于POST请求，它需要ContentType作为参数。所以我在编译时收到一条消息：

变量内容类型已在方法验证地址中定义

庞。xml文件：

swagger文件:

/addresses/validate:
    post:
      tags:
      - Addresses
      operationId: validateAddress
      description: Validate address
      parameters:
      - name: Authorization
        in: header
        required: true
        type: string
      - name: Content-Type
        in: header
        description: ...
        required: true
        type: string
      - name: addressRequest
        in: body
        description: The address request to validation
        required: true
        schema:
          $ref: "#/definitions/AddressRequest"
...

生成的Api类：

    public void validateAddress(String authorization, String contentType, AddressRequest addressRequest) throws RestClientException {
        Object postBody = addressRequest;

        // verify the required parameter 'authorization' is set
        if (authorization == null) {
            throw new HttpClientErrorException(HttpStatus.BAD_REQUEST, "Missing the required parameter 'authorization' when calling validateAddress");
        }

        // verify the required parameter 'contentType' is set
        if (contentType == null) {
            throw new HttpClientErrorException(HttpStatus.BAD_REQUEST, "Missing the required parameter 'contentType' when calling validateAddress");
        }

        // verify the required parameter 'addressRequest' is set
        if (addressRequest == null) {
            throw new HttpClientErrorException(HttpStatus.BAD_REQUEST, "Missing the required parameter 'addressRequest' when calling validateAddress");
        }

        String path = UriComponentsBuilder.fromPath("/addresses/validate").build().toUriString();

        final MultiValueMap<String, String> queryParams = new LinkedMultiValueMap<String, String>();
        final HttpHeaders headerParams = new HttpHeaders();
        final MultiValueMap<String, Object> formParams = new LinkedMultiValueMap<String, Object>();

        if (authorization != null)
        headerParams.add("Authorization", apiClient.parameterToString(authorization));
        if (contentType != null)
        headerParams.add("Content-Type", apiClient.parameterToString(contentType));

        final String[] accepts = { };
        final List<MediaType> accept = apiClient.selectHeaderAccept(accepts);
        final String[] contentTypes = { };
        final MediaType contentType = apiClient.selectHeaderContentType(contentTypes);

        String[] authNames = new String[] {  };

        ParameterizedTypeReference<Void> returnType = new ParameterizedTypeReference<Void>() {};
        apiClient.invokeAPI(path, HttpMethod.POST, queryParams, postBody, headerParams, formParams, accept, contentType, authNames, returnType);
    }

如何解决这个问题？谢谢！

发生这种情况是因为局部变量名与生成代码中的参数名冲突。添加

<configOptions>
    ...
    <localVarPrefix>localVar</localVarPrefix>
</configOptions>
