Json使用restTemplate在android中解析（BEGIN_ARRAY但是BEGIN_OBJECT）

我使用android rest模板解析我的android项目中的json服务 . 当我尝试解析json我有一些错误 .

error:

**org.springframework.http.converter.HttpMessageNotReadableExeption:
Could not read JSON:java.lang.IllegalStateExeption:
Exepted BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2;
nested exception in com.google.gson.JsonSyntaxException:java**

.......等等

Here is my json:

{
    "kategorijaartikla": [
        {
            "id": "1",
            "kategorija": "kategorija1"
        },
        {
            "id": "2",
            "kategorija": "kategorija2"
        }
    ]
}

Here is my RestTemplate code:

String url = "http://tomcat.fit.ba/asdf/rest/GetAllKategorije";
    HttpHeaders requestHeaders = new HttpHeaders();
    requestHeaders.setAccept(Collections.singletonList(new MediaType("application","json")));

    HttpEntity<?> requestEntity = new HttpEntity<Object>(requestHeaders);       
    GsonHttpMessageConverter messageConverter = new GsonHttpMessageConverter();
    List<HttpMessageConverter<?>> messageConverters = new ArrayList<HttpMessageConverter<?>>();

    messageConverters.add(messageConverter);
    RestTemplate restTemplate = new RestTemplate();

    restTemplate.getMessageConverters().add(messageConverter);
    restTemplate.getMessageConverters().add(new org.springframework.http.converter.json.GsonHttpMessageConverter());

    ResponseEntity<kategorijaartikla[]> responseEntity = restTemplate.exchange(url, HttpMethod.GET, requestEntity, kategorijaartikla[].class);
    kategorijaartikla[] events = responseEntity.getBody();

kategorijaartikla.java

public class kategorijaartikla {private Integer id; private String kategorija; public kategorijaartikla（）{} public Integer getId（）{return id; public void setId（Integer newId）{this.id = newId; public String getKategorija（）{return kategorija; public void setKategorija（String newKategorija）
