从项目开始的Java开发学习

　　积累了一些项目中见到的代码，希望见一次之后自己也能写出来。

一.通过cxf JaxWsDynamicClientFactory进行WebService 客户端调用

　　代码：在项目中从非项目内的接口获取数据

    public Object hospitalApiResponse(String paramXml,String subHospitalID){
        //打印 入参 xml
        logger.info(">>>>>>>>>>>>调用web Service服务接口入参为："+paramXml+"<<<<<<<<<<<<<");
        //创建客户端
        JaxWsDynamicClientFactory dcf =JaxWsDynamicClientFactory.newInstance();
        //通过缓存获取url
        Object wsdlUrlObj = ConcurrentHashMapCacheUtils.getCache(subHospitalID);
        if (wsdlUrlObj == null) {
            //如果缓存中没有存值，则清空所有缓存，从数据中重新查出来放入缓存中
            ConcurrentHashMapCacheUtils.clear();
            List<HospitalList> hospitalList = appService.findHospitalList();
            for (HospitalList hos : hospitalList) {
                //设置缓存参数
                ConcurrentHashMapCacheUtils.setCache(hos.getHospitalId(), hos.getWsUrl());
            }
        }
        Object wsdlUrlNew = ConcurrentHashMapCacheUtils.getCache(subHospitalID);
        //如果数据库中也没有就返回 null
        if(wsdlUrlNew == null){
            logger.info(">>>>>>>>>>>>调用web Service服务接口地址不正确<<<<<<<<<<<<<");
            return "服务接口地址异常";
        }
        String wsdlUrl =wsdlUrlNew .toString();
        logger.info(">>>>>>>>>>>>调用web Service服务接口地址为："+wsdlUrl+"<<<<<<<<<<<<<");
        //固定 wsdl url配置
//        String wsdlUrl = hisIdTransitionWsdlUrl(subHospitalID);
        Client client = dcf.createClient(wsdlUrl);
        //定义operationID
        String operationID = WjwConstant.HOSPITAL_FUNTION_STR;
        //接 返回结果值
        Object[] response = new Object[0];
        try {
            //operationID对应方法 ，待后续对接认证
            response = client.invoke(operationID,paramXml);
        } catch (Exception e) {
            logger.error("调用医院接口异常", e);
            e.printStackTrace();
        }
        logger.info(">>>>>>>>>>>>调用web Service服务接口返回结果为："+response[0]+"<<<<<<<<<<<<<");
            return response[0];
    }

public Object hospitalApiResponse(String paramXml,String subHospitalID)

二、java Document生成和解析xml

　　代码：

    public static String hospitalDepartmentsXml(String subHospitalID){
        Document doc = DocumentHelper.createDocument();
        Element rootEle = doc.addElement("root");
        Element operationIDEle = rootEle.addElement("operationID");
        Element subHospitalIDEle = rootEle.addElement("subHospitalID");
        operationIDEle.setText("8002");
        subHospitalIDEle.setText(subHospitalID);
        String result = HospitalApiXmlUtil.xmlWriterUtil(doc);
        return result;
    }

public static String hospitalDepartmentsXml(String subHospitalID)
