Spring消耗剩余JSON Web服務錯誤

Question

下面的代碼導致錯誤

public ArrayList<model.SampleObject> getObjectByNameGet(String name) {

    final String uri = "http://127.0.0.1:8080/services/example/{name}" ;


    Map<String, String> map = new HashMap<String, String>();
    map.put("name", name);


    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<SampleObject[]> responseEntity = null;
    try {
        responseEntity = restTemplate.getForEntity(uri, SampleObject[].class,map);
    } catch (HttpStatusCodeException e) {
        String errorpayload = e.getResponseBodyAsString();
        throw e;
    } catch (RestClientException e) {
        throw e;
    }

    model.SampleObject result = restTemplate.getForObject(uri, model.SampleObject.class);
    SampleObject resultOut[] = responseEntity.getBody();

    ArrayList<SampleObject> arrayList = new ArrayList<SampleObject>(Arrays.asList(resultOut));
    return arrayList;

}

在這條線上：

responseEntity = restTemplate.getForEntity(uri, SampleObject[].class,map);

但是服務是實時且可訪問的，其本地服務已運行

錯誤：

org.springframework.web.client.ResourceAccessException: I/O error on GET request for "http://127.0.0.1:8080/services/example/m":Permission denied: connect; nested exception is java.net.SocketException: Permission denied: connect

我添加-Djava.net.preferIPv4Stack = true到intellij VM選項也沒有運氣。

錯誤原因是什么？ 提前致謝

Answer 1

經過長時間的Google和研究，我發現了問題的根源。 窗口8中存在一個錯誤，該錯誤導致Java套接字無法連接到任何URL。

在Windows 7測試中沒有問題。
