Description

I am trying to generate the necessary models for my API spec in springboot, however I am noticing issues with the generated files that utilize the oneOf keyword. I’d be more than happy to give more information on the specifics I am dealing with, but I’d first like to know if this is fully supported yet in my use case (java/springboot).

OneOfJobConfigs:
      title: OneOfJobConfigs
      oneOf:
        - $ref: '#/components/schemas/ObjectiveAJobConfig'
        - $ref: '#/components/schemas/ObjectiveBJobConfig'
        - $ref: '#/components/schemas/ObjectiveCJobConfig'
      discriminator:
        propertyName: job_config

@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "job_config", visible = true)
@JsonSubTypes({
  @JsonSubTypes.Type(value = JobsConfigCreateInput.class, name = "JobsConfigCreateInput"),
  @JsonSubTypes.Type(value = ObjectiveAJobConfig.class, name = "ObjectiveAJobConfig"),
  @JsonSubTypes.Type(value = ObjectiveBJobConfig.class, name = "ObjectiveBJobConfig"),
  @JsonSubTypes.Type(value = ObjectiveCJobConfig.class, name = "ObjectiveCJobConfig")
})

@Data
@Builder
@NoArgsConstructor
@AllArgsConstructor
public class OneOfJobConfigs {
  @JsonProperty("job_config")
  @Valid 
  private ObjectiveBJobConfigJobConfig jobConfig;

}

This is the generated model, but I need to be able to access all three Objective#JobConfigs from this.

Steps to reproduce

Use oneOf somewhere in your openAPI spec, and run the generate mvn command.

I'm having similar issues with an anyOf in the National Weather Service's public API.

    JsonLdContext:
      anyOf:
        -
          type: array
          items: {  }
        -
          type: object

The code generated can't handle when an Array is returned, even though the spec says it should be fine.

please try java (jesery2) client generator with the latest master as we've merged a PR to support array in oneOf

you can find snapshot version in project's readme.
