将 object 与 setter 转换为 java 中的映射

Question

我需要创建 RequestContext 的映射并将其作为 header 在 BindingProvider 中设置。我目前的代码如下。我需要用各自的 setter 创建一个映射，并将其作为 header.

的 put() 方法的第二个参数传递

RequestContext requestContextBody = new RequestContext();
requestContextBody.setVersion("1.4");
requestContextBody.setLanguage(Language.EN);
requestContextBody.setGroupID("111");
requestContextBody.setRequestReference("UserRef");
requestContextBody.setUserToken(new JAXBElement<String>(new QName("http://purolator.com/pws/datatypes/v1","UserToken"), String.class, "7a0f98ec-6e9f-4eb1-9fcb-40086e2c1040"));

URL wsdlURL = PurolatorClientImpl.class.getClassLoader().getResource("wsdl/EstimatingService.wsdl");
EstimatingService ss = new EstimatingService(wsdlURL, SERVICE_NAME);
EstimatingServiceContract port = ss.getEstimatingServiceEndpoint();

((BindingProvider) port).getRequestContext().put(MessageContext.HTTP_REQUEST_HEADERS, requestContextBody); //THIS IS WHERE I NEED TO PASS THE MAP IN PLACE OF THE REQUESTCONTEXTBODY OBJECT
((BindingProvider) port).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "867aa05887b94f48988b6bf46340c5b3");
((BindingProvider) port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "Ze@5l22N");

如javadocs所述MessageContext.HTTP_REQUEST_HEADERS需要一个java.util.Map

所以你可以试试这个：

Map context = ((BindingProvider) port).getRequestContext();
Map<String, List<String>> requestHeaders = (Map) context.get(MessageContext.HTTP_REQUEST_HEADERS) ;
requestHeaders.put("User-Agent", Collections.singletonList("Mozilla [...]"));
// add all yours setting
context.put(MessageContext.HTTP_REQUEST_HEADERS, headers);
