Spring RestTemplate how to use POJO with application/x-www-form-urlencoded?

When I try to use POJO with MediaType.APPLICATION_FORM_URLENCODED

    ExampleRequest exampleRequest = exampleRequest();
    exampleRequest.setId("id");
    exampleRequest.setName("name");

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

    HttpEntity<ExampleRequest> exampleRequestEntity = new HttpEntity<>(exampleRequest, headers);

    restTemplate.postForObject(url, exampleRequestEntity, String.class)

I get:

org.springframework.web.client.RestClientException: No HttpMessageConverter for [ExampleRequest] and content type [application/x-www-form-urlencoded]

Is there any way to use POJO with application/x-www-form-urlencoded instead of MultiValueMap<String, String> map?

FormHttpMessageConverter might be missing. Have you tried adding it manually? 

@SpringBootApplication
public class App extends WebMvcConfigurerAdapter {

    public static void main(String[] args) {
        SpringApplication.run(App.class);
    }

    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        FormHttpMessageConverter converter = new FormHttpMessageConverter();
        MediaType mediaType = new MediaType("application","x-www-form-urlencoded", Charset.forName("UTF-8"));
        converter.setSupportedMediaTypes(Arrays.asList(mediaType));
        converters.add(converter);
        super.configureMessageConverters(converters);
    }
}

(Relevant for spring boot)

There is possible to use the FormHttpMessageConverter which is able to convert data to/from a MultiValueMap<String, String> required for the application/x-www-form-urlencoded media type. Add the following configuration to the class implementing WebMvcConfigurer.

@Bean
public FormHttpMessageConverter formHttpMessageConverter() {

    MediaType mediaType = new MediaType("application", "x-www-form-urlencoded", 
        Charset.forName("UTF-8"))

    FormHttpMessageConverter formHttpMessageConverter= new FormHttpMessageConverter();
    formHttpMessageConverter.setSupportedMediaTypes(Collections.singletonList(mediaType));
    return formHttpMessageConverter;
}

@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
     converters.add(formHttpMessageConverter());
     super.configureMessageConverters(converters);
}
