本文介绍了java.lang.IllegalStateException：不是JSON对象的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ 我正在尝试使用SonarQube Web API从SonarQube获取json响应。将 JsonElement 分配到 JsonObject 时，我收到此错误：I am trying to get a json response from SonarQube using the SonarQube web API. While assigning the JsonElement into a JsonObject I am getting this error:java.lang.IllegalStateException: Not a JSON Object 这是我的Java类This is my Java class@Controllerpublic 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(); } }}

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