Request Body for Maps not available in Swagger-UI

[mburri]

Describe the bug

Given a ressource that excpects a request body of the following type:
@RequestBody HashMap<String, String> body

The Request Body is not available in the Swagger-UI for the resource since springdoc-openapi-ui 1.3.1
But it works in springdoc-openapi-ui 1.3.0

To Reproduce
Steps to reproduce the behavior:

• What version of spring-boot you are using?
  Spring Boot 2.2.6

• What modules and versions of springdoc-openapi are you using?
  1.3.1 (also tested with 1.3.4 - same issue)

• What is the actual and the expected result using OpenAPI Description (yml or json)?

the requestbody is not available in the UI - but it should be. The generated api docs is the same for springdoc-openapi-ui 1.3.0 and 1.3.1

• Provide with a sample code (HelloController) or Test that reproduces the problem

    @PostMapping
    public ResponseEntity<HashMap<String, Object>> hello(@RequestBody HashMap<String, Object> map) {
        return ResponseEntity.ok(map);
    }

Expected behavior

• A clear and concise description of what you expected to happen.

When trying out the API in Swagger UI - I should be able to pass in the request body.

Screenshots

Hi @mburri,

In fact its normal that Maps are ignored:

• https://springdoc.org/faq.html#what-are-the-ignored-types-in-the-documentation

With v1.3.4, you have a first workaround which is:

static {
	SpringDocUtils.getConfig().removeRequestWrapperToIgnore(java.util.Map.class);
}

For your case, because if you are using @RequestBody spring annotation before the parameter, it shouldn't be ignored as its required by default.
So the behaviour you are expecting will be out of the box, starting from the next release v1.3.5.
