webservice cxf客户端自定义参数

序

WebService真是烦，为了不想写那些烦人的适配代码，使用了CXF 生成的客户端，但遇到要填自定义参数的时候，却无从入手。。。
经过几天的研究，各种尝试，解读原码。终于把问题解决，项目终于可以顺序进行下去了。。

遇到的问题

1：SAP 提供的webService 要求输入账号验证信息，如下图所示，但是使用生成的CXF客户端却没有一个属性可以配置。

问题解决

整个代码如下（已经脱敏）：
实现的是一个定时把需要地接的数据，通过webservice 发送到目标系统。

                BeanUtils.copyProperties(wrap,en);
                data.getWTYPOST().add(en);

                com.ly.mp.swcas.wsInvoker.DTWTYPOSTRes wsResult = _port.siWTYPOST(data);
                if (wsResult != null && !CollectionUtils.isEmpty(wsResult.getWTYPOST())) {
                    task.setResponseContent(new Gson().toJson(wsResult));
                    DTWTYPOSTRes.WTYPOST it = wsResult.getWTYPOST().get(0);
                    if ("S".equals(it.getStats())) {
                        task.setSendStatus("1");
                    } else {
                        task.setSendStatus("2");
                    }
                }
            } catch (Exception ex) {
                ex.printStackTrace();
                StringWriter stringWriter = new StringWriter();
                ex.printStackTrace(new PrintWriter(stringWriter));
                task.setResponseContent(stringWriter.toString());
            }
            watch.stop();
            task.setSendCost(BigDecimalUtils.val(watch.getTotalTimeSeconds()));
            task.setLastUpdatedDate(new Date());
            task.setTryAcc(task.getTryAcc() + 1);
            biz.updateTask(task);
        }
        System.out.println("-------------end SapFinanceSendTask job--------------");
        return rs;
    }

}

关键:把Port转换成BindingProvider，然后给port赋值，如下：

 public SIWTYPOST getPort() throws MalformedURLException {

        if (_port != null) return _port;
        URL wsdlURL = new URL(wsdlPath);
        QName SERVICE_NAME = new QName("http://**.com/SWCAS/I080302WarrantyPost", "SI_WTY_POSTService");
        SIWTYPOSTService ss = new SIWTYPOSTService(wsdlURL, SERVICE_NAME);
        _port = ss.getHTTPPort();
        ((BindingProvider) _port).getRequestContext().put(BindingProvider.USERNAME_PROPERTY, "userName");
        ((BindingProvider) _port).getRequestContext().put(BindingProvider.PASSWORD_PROPERTY, "password");
        return _port;
    }

PS：原代码主要关注初始化，与及getHttpPort两个方法。说实话，原代码真的很臭，希望不要再见。。
