Get list of JSON objects with Spring RestTemplate

I have two questions:

• How to map a list of JSON objects using Spring RestTemplate.
• How to map nested JSON objects.

I am trying to consume https://bitpay.com/api/rates, by following the tutorial from http://spring.io/guides/gs/consuming-rest/.

First define an object to hold the entity coming back in the array.. e.g.

@JsonIgnoreProperties(ignoreUnknown = true)
public class Rate {
    private String name;
    private String code;
    private Double rate;
    // add getters and setters
}

Then you can consume the service and get a strongly typed list via:

ResponseEntity<List<Rate>> rateResponse =
        restTemplate.exchange("https://bitpay.com/api/rates",
                    HttpMethod.GET, null, new ParameterizedTypeReference<List<Rate>>() {
            });
List<Rate> rates = rateResponse.getBody();

The other solutions above will also work, but I like getting a strongly typed list back instead of an Object[].

Maybe this way...

ResponseEntity<Object[]> responseEntity = restTemplate.getForEntity(urlGETList, Object[].class);
Object[] objects = responseEntity.getBody();
MediaType contentType = responseEntity.getHeaders().getContentType();
HttpStatus statusCode = responseEntity.getStatusCode();

Controller code for the RequestMapping

@RequestMapping(value="/Object/getList/", method=RequestMethod.GET)
public @ResponseBody List<Object> findAllObjects() {

    List<Object> objects = new ArrayList<Object>();
    return objects;
}

ResponseEntity is an extension of HttpEntity that adds a HttpStatus status code. Used in RestTemplate as well @Controller methods. In RestTemplate this class is returned by getForEntity() and exchange().

For me this worked

Object[] forNow = template.getForObject("URL", Object[].class);
    searchList= Arrays.asList(forNow);

Where Object is the class you want
