我正在尝试使用 SonarQube Web API 从 SonarQube 获取 json 响应。在分配JsonElement到 aJsonObject时，我收到此错误：

java.lang.IllegalStateException: Not a JSON Object

这是我的 Java 类

@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();
        }

    }
}

这是我的 Json 回复

read as JSONArray 读取 jsonarray

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

不是 JSON 对象：[{"id":2772,"uuid":"AVeKDMBLuPlc0jzh2Dos"..... 在您的 API 响应起点中，JSONArray 不是 JSONObject，所以java.lang.IllegalStateException: Not a JSON Object:请添加@rathna 回答的 if 条件，如下所示

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

我认为rathna的代码中可能存在一个小错误。由于jelement.getAsJsonObject()已经是 a JsonObject，因此构造函数是多余的。这是对我有用的代码：

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