我正在使用Maven，Java 1.6，Apache CXF。我在某些Apache CXF类中调用Soap API时遇到了一些Class Cast异常。这是堆栈跟踪。

以下是我正在使用的代码：
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);

List<CapturedData> capturedDataList = dynamicsDao.getCapturedData(startDate.getTime(), endDate.getTime());
FKPG fkpg = new FKPG();
fkpg.getContent().addAll(capturedDataList);
resp = opsRequestManagementPort.importCapturedData(fkpg);
答案 0 :(得分：3)
@sadhu的回答指出了我自己问题的正确方向，但这对我来说太过神秘了。
拿这个片段：
wsdlURL = new URL("some http url with requiring basic authentication");
这告诉我们wsdlURL的类型为java.net.URL。接下来我们发现：
Map<String, Object> req_ctx = ((BindingProvider) opsRequestManagementPort).getRequestContext();
req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, wsdlURL);
要解决此问题，请将最后一行更改为：
req_ctx.put(BindingProvider.ENDPOINT_ADDRESS_PROPERTY, wsdlURL.toExternalForm());
关键是你应该在地图中放置一个String对象，而不是URL个实例。
为了防止将来发生这种情况，请始终检查Javadoc。这就是ENDPOINT_ADDRESS_PROPERTY所说的:(强调我的）
标准属性：目标服务端点地址。端点地址规范的URI方案必须与正在使用的绑定的协议/传输绑定相对应。
输入：java.lang.String
答案 1 :(得分：0)
我很确定， wsdlURL 的类型是String，它不应该是。代替
URL wsdlURL
