IMO, schema type is missing here.

Suggested change

	"ExamplesResponse": {
	"ExamplesResponse": {
	"type": "object",

[xiaoxiangmoe]

@JohnNiang It seems that the current unit test also not include "type": "object"

springdoc-openapi/springdoc-openapi-starter-webmvc-api/src/test/resources/results/3.1.0/app7.json

Lines 37 to 60 in d4f99ac

	"ExamplesResponse": {
	"properties": {
	"name": {
	"type": "string",
	"description": "name",
	"examples": [
	"name"
	]
	},
	"subject": {
	"type": "string",
	"description": "subject",
	"example":"Hello",
	"examples": [
	"Hello",
	"World"
	]
	}
	},
	"required": [
	"name",
	"subject"
	]
	}

See here: https://spec.openapis.org/oas/v3.1.0#data-types

Data types in the OAS are based on the types supported by the JSON Schema Specification Draft 2020-12.

In JSON Schema Specification Draft 2020-12, "type" field is optional, so this is valid JSON schema.

And the api-gen is done by swagger-core. We can advise swagger-core to provide "type": "object".

@uc4w6c Can you review it?

@xiaoxiangmoe
Sorry for the late confirmation.
Since I don't have merge privileges, I requested bnasslahsen to be a reviewer.

I thought it might be better to combine it with the test code below.
