不用任何框架开发web service

很讨厌webservice框架配置的繁琐
尤其是axis系列
一怒之下直接用servlet开发了
其实也很简单，关键是要获取到请求soap和响应soap，可借助soapUI来生成
soapUI的使用这里不做介绍

生成请求soap和响应soap后关键就是解析soap了
直接用的java提供的API来解析
解析请求Soap
代码如下：

public class SyncNotifySPReqDecoder {
	private static Logger logger = LoggerFactory.getLogger(SyncNotifySPReqDecoder.class);
	
	public static SyncNotifySPReq decode(InputStream in){
		DocumentBuilderFactory domfac=DocumentBuilderFactory.newInstance();
		String recordSequenceId = "0";
		List<YingZhangReceiptBody> itemList = new ArrayList<YingZhangReceiptBody>();
		
		try {
			DocumentBuilder dombuilder=domfac.newDocumentBuilder();
			Document doc=dombuilder.parse(in);
			
			Element root=doc.getDocumentElement();
			
			//解析recordSequenceId
			NodeList recordSequenceIdNodeList = root.getElementsByTagName("recordSequenceId");
			if(recordSequenceIdNodeList.getLength() >= 1){
				recordSequenceId = recordSequenceIdNodeList.item(0).getTextContent();
			}

			
			//解析item
			NodeList itemNodeList = root.getElementsByTagName("item");
			
			for (int i = 0; i < itemNodeList.getLength(); i++) {
				Node item = itemNodeList.item(i);
				
				String userIdType = getNodeValue(item, "userIdType");
				String userId = getNodeValue(item, "userId");
				String sp_productId = getNodeValue(item, "sp_productId");
				String updateType = getNodeValue(item, "updateType");
				
				//UserIdType填1 为手机号码 ; UserIdType填2 为伪码
				if( "1".equals(userIdType) ){
					YingZhangReceiptBody body = new YingZhangReceiptBody(remove86(userId), sp_productId, escapeServiceCode(updateType));
					itemList.add(body);
				}
			}
			
		} catch (Exception e) {
			logger.error(e.getMessage(), e);
		}
		
		return new SyncNotifySPReq(recordSequenceId, itemList);
	}
	
	

	
	//获取Node Value
	public static String getNodeValue(Node item, String nodeName){
		for(Node n=item.getFirstChild(); n != null; n=n.getNextSibling()){
			if(n.getNodeType() == Node.ELEMENT_NODE){
				if(n.getNodeName().equals(nodeName)){
					return n.getTextContent();
				}
			}
		}
		
		return null;
	}
}

写响应SOAP

public class SyncNotifySPResEncoder {
	
	/**
	 * 返回soap响应
	 * @param recordSequenceId
	 * @param resultCode 0: 成功; 1. 失败
 
	 */
	public static String encode(String recordSequenceId, int resultCode){
		StringBuilder ret = new StringBuilder("<soapenv:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soapenv=\"http://schemas.xmlsoap.org/soap/envelope/\" xmlns:soap=\"http://soap.bossagent.vac.unicom.com\">");
		ret.append("<soapenv:Header/>")
			.append("<soapenv:Body>")
			.append("<soap:orderRelationUpdateNotifyResponse soapenv:encodingStyle=\"http://schemas.xmlsoap.org/soap/encoding/\">")
			.append("<orderRelationUpdateNotifyReturn xsi:type=\"rsp:OrderRelationUpdateNotifyResponse\" xmlns:rsp=\"http://rsp.sync.soap.bossagent.vac.unicom.com\">")
			.append("<recordSequenceId xsi:type=\"soapenc:string\" xmlns:soapenc=\"http://schemas.xmlsoap.org/soap/encoding/\">")
			.append(recordSequenceId)
			.append("</recordSequenceId>")
			.append("<resultCode xsi:type=\"xsd:int\">")
			.append(resultCode)
			.append("</resultCode>")
			.append("</orderRelationUpdateNotifyReturn>")
			.append("</soap:orderRelationUpdateNotifyResponse>")
			.append("</soapenv:Body>")
			.append("</soapenv:Envelope>");
		
		return ret.toString();
	}
	
}

就是这么简单
