使用Java HttpURLConnection方式调用webService

第一步（读取配置文件）：
public class PropertiesUtil {
    private static final Logger logger = LoggerFactory
            .getLogger(PropertiesUtil.class);
    private static Properties properties = null;
    private static String fileName = "/app.properties";
    static {
        properties = new Properties();
        try {
            properties.load(PropertiesUtil.class.getResourceAsStream(fileName));
        } catch (IOException e) {
            logger.error("加载配置文件失败", e);
        }
    }

    public static Properties getProperties() {
        return properties;
    }

    public static String getProp(String propName) {
        return properties.getProperty(propName);
    }
}

第二步：
public static Map<String, String> resultInterface(String id,String type, String jsonStr) {
    StringBuilder res = new StringBuilder();
    // 1：创建服务地址
    URL url;
    String resultUserName = PropertiesUtil.getProp("resultUserName");
    String resultPassWord = PropertiesUtil.getProp("resultPassWord");
    Map<String, String> map = new HashMap<String, String>();
    try {
      url = new URL(PropertiesUtil.getProp("resultUrl"));
      // 2：打开到服务地址的一个连接
      HttpURLConnection connection = (HttpURLConnection) url.openConnection();
      // 3：设置连接参数
      // 3.1设置发送方式：POST必须大写
      connection.setRequestMethod("POST");
      // 3.2设置数据格式：Content-type
      connection.setRequestProperty("content-type", "text/xml;charset=utf-8");
      // 3.3设置输入输出，新创建的connection默认是没有读写权限的，
      connection.setDoInput(true);
      connection.setDoOutput(true);
      //"{\"ANNOUNCEMENT_CODE\": \"CSGGBH001\",\"ANNOUNCEMENT_CONNECT\": \"asdfasdfasdfasdfasdfasdfasdfsa\",\"ANNOUNCEMENT_DEADLINE\": \"20181031\",\"ANNOUNCEMENT_GUID\": \"71F15848-C296-4A60-883C-223C55E9E8D8\",\"ANNOUNCEMENT_START_TIME\": \"20181101\",\"ANNOUNCEMENT_TITLE\": \"公告标题\",\"ANNOUNCEMENT_TYPE\": \"1\",\"ANNOUNCEMENT_UNIT\": \"单位\",\"ATTACHMENT_SET_CODE\": \"123\",\"CANCEL_REASON\": \"撤销理由\",\"CHANGE_TIME\": \"20181101\",\"CONTACT_NUMBER\": \"13333333333\",\"CONTACT_PERSON\": \"联系人\",\"CREATE_TIME\": \"20181101\",\"DATA_TIMESTAMP\": \"20181101154911\",\"EMAIL\": \"123@qq.com\",\"END_DATE\": \"20181101\",\"FIELD_NUM\": \"123\",\"LAND_DISTRICT\": \"440601\",\"LIAISON_UNIT\": \"单位\",\"LISTING_DEADLINE\": \"\",\"LISTING_START_TIME\": \"\",\"LISTING_TYPE\": \"0\",\"PLATFORM_CODE\": \"91441900708017879M\",\"PUBLISHING_TIME\": \"20181101\",\"PUB_SERVICE_PLAT_CODE\": \"123707003283632515\",\"RETREAT_TIME\": \"20181101\",\"SUPPLY_TYPE\": \"1\",\"UNIFIED_DEAL_CODE\": \"B01-123707003283632515-20181025-000015-V\",\"UNIT_ADDRESS\": \"单位地址\",\"URL\": \"http://www.baidu.com\",\"ZIP_CODE\": \"215600\"}";

      // 4：组织SOAP协议数据，发送给服务端
      String soapXML = "<soap12:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap12=\"http://www.w3.org/2003/05/soap-envelope\">"

      OutputStream os = connection.getOutputStream();
      os.write(soapXML.getBytes());

      // 5：接收服务端的响应

        }
        
        is.close();
        isr.close();
        br.close();
        String xml = res.toString();
        Document doc = DocumentHelper.parseText(xml); // 将字符串转为XML
