[BUG] [SPRING] Missing Java Bean Validation annotations on RequestBody

Created by: Mintas

Description

We are unable to generate beanValidation annotations for RequestBody params. Looks like the feature was missing in revision 8952815b

Proposed changes should cover this bug and allow beanValidation annotations to be generated on RequestBody params too.

openapi-generator version

6.2.1 , current master

OpenAPI declaration file content or url

Provided configuration:

paths:
  /add:
    post:
      requestBody:
        content:
          application/json:
            schema:
              type: integer
              title: quantity
              minimum: 2
        required: true
      responses:
        '200':
          description: OK
          content:
            application/json:
              schema:
                type: boolean

Generates:

@Operation(
        operationId = "addPost",
        responses = {
            @ApiResponse(responseCode = "200", description = "OK", content = @Content(mediaType = "application/json", schema = @Schema(implementation =  Boolean.class)))
        }
    )
    @RequestMapping(
        method = RequestMethod.POST,
        value = "/add",
        produces = { "application/json" },
        consumes = { "application/json" }
    )
    default ResponseEntity<Boolean> cartKekPost(
        @Parameter(name = "body", description = "", required = true) @Valid @RequestBody Integer body
    ) {
        return new ResponseEntity<>(HttpStatus.NOT_IMPLEMENTED);

    }

Must have:

    default ResponseEntity<Boolean> addPost(
        @Min(2)  @Parameter(name = "body", description = "", required = true) @Valid @RequestBody Integer body
    ) {
        return new ResponseEntity<>(HttpStatus.NOT_IMPLEMENTED);

    }

Command line used for generation

Plugin configuration: (beanValidation is enabled by default)

generatorName = 'spring' configOptions = [ dateLibrary: 'java8', interfaceOnly: 'true', openApiNullable: 'false', java8: 'false' ] importMappings = ['java.time.OffsetDateTime': 'java.time.Instant'] typeMappings = ['OffsetDateTime': 'Instant']

Steps to reproduce

./gradlew openApiGenerate
