Java attribute of type object is incorrectly mapped to an OpenApi property of type object #4457
Description
Related: OpenAPITools/openapi-generator#16110
Description
A Java attribute of type object can be any instance of an object, e.g. String, Boolean, Long and so on. However, the resulting OpenApi specification assigns this attribute to an object of type object, which must be a JSON object, that is a map.
Example
The following java class can be used as a minimal example:
public class Pet{
private Long id;
@Schema(description = "A string, a number or a boolean", anyOf = { String.class, Number.class, Boolean.class })
private Object name;
}This generates the following openapi.yaml:
...
properties:
name:
type: object
description: "A string, a number or a boolean"
anyOf:
- type: string
- type: integer
format: int64
- type: number
format: double
- type: boolean
...whereas the following would be correct:
...
properties:
name:
description: "A string, a number or a boolean"
anyOf:
- type: string
- type: integer
format: int64
- type: number
format: double
- type: boolean
