Transform输出xml并且更改版本为1.1

简介

java jdk绑定的jar库以为版本很老，所以不支持生成xml version1.1,所以为了解决这个问题我们需要引入 xalan-2.7.2包，Jdk测试版本jdk1.8.0_40-b26，具体可参考官方文档

gradle引入：

    compile ('xalan:xalan:2.7.2')

测试代码 

@Testpublic void smlVersionTest() throws TransformerException, ParserConfigurationException {TransformerFactory transformerFactory = TransformerFactory.newInstance();Transformer transformer = transformerFactory.newTransformer();Document doc = createResponseDocument();DOMSource source = new DOMSource(doc);StreamResult result = new StreamResult(new File("xmlVerTest.xsd"));transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");transformer.setOutputProperty(OutputKeys.INDENT, "yes");transformer.setOutputProperty(OutputKeys.METHOD, "xml");// 更改版本，xml默认为1.0transformer.setOutputProperty(OutputKeys.VERSION, "1.1");transformer.setOutputProperty(OutputPropertiesFactory.S_KEY_INDENT_AMOUNT, "2");transformer.transform(source, result);}private Document createResponseDocument() throws ParserConfigurationException {DocumentBuilderFactory dbfactory = DocumentBuilderFactory.newInstance();DocumentBuilder builder = dbfactory.newDocumentBuilder();Document responseDocument = builder.newDocument();Element rootElement = responseDocument.createElement("root");responseDocument.appendChild(rootElement);Element statusMessageElement = responseDocument.createElement("statusMessage");rootElement.appendChild(statusMessageElement);Element requestElement = responseDocument.createElement("request");rootElement.appendChild(requestElement);Map<String, String> requestParameter = new HashMap<>();requestParameter.put("xmlVer", "1.1");return responseDocument;}
