Brings basic discriminator based OneOf Support to the JavaSpring generator. It generates a marker Interface which the oneOf Models then implement. Technically it requires Jackson based models and is implemented using @JsonTypeInfo and @JsonSubTypes based using a discriminator property.
The relevant Code ist moved to AbstractJavaCodegen and aligned with the other Java based generators in the hierarchy.
The oneOf Support is implemented by utilizing the x-implements vendor extension.
Currently It is enabled in the SpringCodegen only:
useOneOfInterfaces = true;
legacyDiscriminatorBehavior = false;
Synopsis
@JsonTypeInfo(use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.EXISTING_PROPERTY, property = "@type", visible = true)
@JsonSubTypes({
@JsonSubTypes.Type(value = Foo.class, name = "Foo"),
@JsonSubTypes.Type(value = FooRef.class, name = "FooRef")
})
@Generated(value = "org.openapitools.codegen.languages.SpringCodegen")
public interface FooRefOrValue {
public String getAtType();
}
