Как установить описание и пример в Swagger с помощью аннотаций Swagger?

Я создаю REST Api, используя Spring boot, и автоматически генерирую документацию swagger в контроллерах, используя swagger codegen. Однако я не могу установить описание и пример для параметра типа String в запросе POST. Вот ми код:

import io.swagger.annotations.*;

@Api(value = "transaction", tags = {"transaction"})
@FunctionalInterface
public interface ITransactionsApi {
    @ApiOperation(value = "Places a new transaction on the system.", notes = "Creates a new transaction in the system. See the schema of the Transaction parameter for more information ", tags={ "transaction", })
    @ApiResponses(value = {
        @ApiResponse(code = 200, message = "Another transaction with the same messageId already exists in the system. No transaction was created."),
        @ApiResponse(code = 201, message = "The transaction has been correctly created in the system"),
        @ApiResponse(code = 400, message = "The transaction schema is invalid and therefore the transaction has not been created.", response = String.class),
        @ApiResponse(code = 415, message = "The content type is unsupported"),
        @ApiResponse(code = 500, message = "An unexpected error has occurred. The error has been logged and is being investigated.") })

    @RequestMapping(value = "/transaction",
        produces = { "text/plain" },
        consumes = { "application/json" },
        method = RequestMethod.POST)
    ResponseEntity<Void> createTransaction(
        @ApiParam(
            value = "A JSON value representing a transaction. An example of the expected schema can be found down here. The fields marked with an * means that they are required." ,
            example = "{foo: whatever, bar: whatever2}")
        @Valid @RequestBody String kambiTransaction) throws InvalidTransactionException;
}

Свойство примера @ApiParam было вставлено мной вручную, потому что codegen игнорировал эту часть yaml (Это другой вопрос: почему редактор игнорирует часть примера?). Вот часть Ямла:

paths:
  /transaction:
    post:
      tags:
        - transaction
      summary: Place a new transaction on the system.
      description: >
        Creates a new transaction in the system. See the schema of the Transaction parameter
        for more information
      operationId: createTransaction
      parameters:
        - $ref: '#/parameters/transaction'
      consumes:
        - application/json
      produces:
        - text/plain
      responses:
        '200':
          description: Another transaction with the same messageId already exists in the system. No transaction was created.
        '201':
          description: The transaction has been correctly created in the system
        '400':
          description: The transaction schema is invalid and therefore the transaction has not been created.
          schema:
            type: string
            description: error message explaining why the request is a bad request.
        '415':
          description: The content type is unsupported
        '500':
          $ref: '#/responses/Standard500ErrorResponse'

parameters:
  transaction:
    name: kambiTransaction
    in: body
    required: true
    description: A JSON value representing a kambi transaction. An example of the expected schema can be found down here. The fields marked with an * means that they are required.
    schema:
      type: string
      example:
        {
          foo*: whatever,
          bar: whatever2
        }

И, наконец, вот что показывает чванство:

Наконец, зависимости, используемые в build.gradle, следующие:

compile group: 'io.springfox', name: 'springfox-swagger2', version: '2.7.0'
compile group: 'io.springfox', name: 'springfox-swagger-ui', version: '2.7.0'

Итак, вопрос: кто-нибудь знает, как я могу установить описание и пример параметра тела, используя аннотации чванства?

РЕДАКТИРОВАТЬ

Мне удалось изменить описание, используя @ApiImplicitParam вместо @ApiParam, но пример по-прежнему отсутствует:

@ApiImplicitParams({
    @ApiImplicitParam(
        name = "kambiTransaction",
        value = "A JSON value representing a transaction. An example of the expected schema can be found down here. The fields marked with * means that they are required. See the schema of KambiTransaction for more information.",
        required = true,
        dataType = "String",
        paramType = "body",
        examples = @Example(value = {@ExampleProperty(mediaType = "application/json", value = "{foo: whatever, bar: whatever2}")}))})

public void post(@PathParam("userId") @ApiParam(value = "userId", example = "4100003") Integer userId) {}

@ApiModel(subTypes = {BalanceUpdate.class, UserMessage.class})

    private final String status;;

@ApiParam(
