Unexpected change in parameter exclusiveMinimum between springdoc-openapi 2.8.6 and 2.8.10

Describe the bug

I'm using springdoc-openapi in my Kotlin project. I've tried to upgrade from version 2.8.6 to 2.8.10, but I've noticed a change in the generated api-docs.

Consider the following code snippet:

@ParameterObject
data class BaseSearchParameters(
    @field:Positive
    @field:Parameter(description = "Page number (1-based).")
    val page: Int = 1,

    @field:Positive
    @field:Parameter(description = "Number of documents per page.")
    val size: Int = ControllerConstants.DEFAULT_PAGE_SIZE,
)

In version 2.8.6, it is not generating the "exclusiveMinimum".

{
    "name": "page",
    "in": "query",
    "description": "Page number (1-based).",
    "required": false,
    "schema": {
        "type": "integer",
        "format": "int32"
    }
},
{
    "name": "size",
    "in": "query",
    "description": "Number of dealers per page. Default is 20.",
    "required": false,
    "schema": {
        "type": "integer",
        "format": "int32"
    }
}

However, in version 2.8.10, it is generating the "exclusiveMinimum":

{
    "name": "page",
    "in": "query",
    "description": "Page number (1-based).",
    "required": false,
    "schema": {
        "type": "integer",
        "format": "int32",
        "exclusiveMinimum": 0
    }
},
{
    "name": "size",
    "in": "query",
    "description": "Number of dealers per page. Default is 20.",
    "required": false,
    "schema": {
        "type": "integer",
        "format": "int32",
        "exclusiveMinimum": 0
    }
}

Besides, according to OpenAPI Documentation, the exclusiveMinimum and exclusiveMaximum should be boolean, but are being generated as numbers.

Thank you for your time and support.

@brunopereira7,

This is expected and related to this PR: #3001

ExclusiveMinimum (and similarly exclusiveMaximum) changed from a boolean in OpenAPI 3.0 to a numeric value in OpenAPI 3.1.

But you can get back previous behavior, by using springdoc.api-docs.version=openapi_3_0
