使用Apache CXF調用SOAP API時發生ClassCastException

Question

我正在使用Maven，Java 1.6，Apache CXF。 在Apache CXF的某些類中調用Soap API時，出現了一些類強制轉換異常。 這是堆棧跟蹤。

這是我正在使用的代碼：

try
    {
        wsdlURL =
                new URL("some http url with requiring basic authentication");
    }
    catch (MalformedURLException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

    System.out.println(wsdlURL);

    OPSRequestManagement opsRequestManagement = new OPSRequestManagement(wsdlURL, SERVICE_NAME);
    OPSRequestManagementPort opsRequestManagementPort = opsRequestManagement.getOPSRequestManagementPort();

    Map<String, Object> req_ctx = ((BindingProvider) opsRequestManagementPort).getRequestContext();
    req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, wsdlURL);

    Map<String, List<String>> headers = new HashMap<String, List<String>>();
    headers.put("Username", Collections.singletonList("domain\\username"));
    headers.put("Password", Collections.singletonList("password"));
    req_ctx.put(MessageContext.HTTP_REQUEST_HEADERS, headers);

    boolean resp;

    List<CapturedData> capturedDataList = dynamicsDao.getCapturedData(startDate.getTime(), endDate.getTime());
    FKPG fkpg = new FKPG();
    fkpg.getContent().addAll(capturedDataList);
    resp = opsRequestManagementPort.importCapturedData(fkpg);

Answer 1

@sadhu的回答為我解決自己的問題指明了正確的方向，但這對我來說太神秘了。

請使用以下代碼段：

wsdlURL = new URL("some http url with requiring basic authentication");

這告訴我們wsdlURL是java.net.URL類型。 接下來，我們發現：

Map<String, Object> req_ctx = ((BindingProvider) opsRequestManagementPort).getRequestContext();
req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, wsdlURL);

要解決此問題，請將最后一行更改為：

req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, wsdlURL.toExternalForm());

關鍵是您應該在地圖中放置一個String對象，而不是URL實例。

---

為防止將來發生這種情況，請始終檢查Javadoc。 ENDPOINT_ADDRESS_PROPERTY的內容如下：（強調我的意思）

標准屬性：目標服務端點地址。 端點地址規范的URI方案必須與使用中的綁定的協議/傳輸綁定相對應。

類型：java.lang.String

Answer 2

我很確定， wsdlURL的類型是String，而不應該是String。 代替

URL wsdlURL
