java.lang.IllegalStateException：JSONオブジェクトではない

SonarQube Web APIを使用してSonarQubeからjson応答を取得しようとしています。 JsonElementをJsonObjectに割り当てると、次のエラーが発生します。

Java.lang.IllegalStateException: Not a JSON Object

これは私のJavaクラスです

@Controller
public class SonarController {

    @Autowired
    JenkinsDataService jenkinsService;
    @Autowired
    SonarDataService sonarService;
    HttpEntity<String> entity;

    @RequestMapping(value = { "/sonar" })
    public void test(HttpServletRequest request, HttpServletResponse response,ModelMap model ) throws ServletException, IOException{
        try{
            String url= "http://sbstpvmlx818:9000/api/resources?metrics=coverage,sonar&depth=1&metrics=ncloc";
            RestTemplate restTemplate = new RestTemplate();

            HttpHeaders headers = new HttpHeaders();
            headers.setAccept(Arrays.asList(MediaType.APPLICATION_JSON));
            entity = new HttpEntity<String>("parameters", headers);
            ResponseEntity<String> sonarResponse = restTemplate.exchange(url, HttpMethod.POST, entity, String.class);

            JsonElement jelement = new JsonParser().parse(sonarResponse.getBody());
            JsonObject  jobject = jelement.getAsJsonObject();
        } catch(Exception e) {
            e.printStackTrace();
        }

    }
}

これは私のJson応答です

jSONArrayとして読み取ってjsonarrayを読み取る

 if (jelement instanceof JsonObject) {
    JsonObject  jobject = new JsonObject(jelement .getAsJsonObject());
 } else if (jelement instanceof JsonArray) {
    JsonArray  jarray =  new JsonArray(jelement.getAsJsonArray());
 }

JSONオブジェクトではありません：[{"id":2772,"uuid":"AVeKDMBLuPlc0jzh2Dos".....ここでは、API応答の開始点はJSONObjectではなくJSONArrayだったので、Java.lang.IllegalStateException: Not a JSON Object:以下の@rathnaによって回答されたif条件を追加してください

if (jelement instanceof JsonObject) {
    JsonObject  jobject = new JsonObject(jelement .getAsJsonObject());
 } else if (jelement instanceof JsonArray) {
    JsonArray  jarray =  new JsonArray(jelement.getAsJsonArray());
 }

rathna のコードに小さな間違いがあると思います。 jelement.getAsJsonObject()はすでにJsonObjectであるため、コンストラクターは冗長です。これが私のために働くコードです：

if (jelement instanceof JsonObject) {
    JsonObject  jobject = jelement.getAsJsonObject();
 } else if (jelement instanceof JsonArray) {
    JsonArray  jarray = jelement.getAsJsonArray();
 }
