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 

@Test
    public 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1.0
        transformer.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 requestParameter = new HashMap<>();
        requestParameter.put("xmlVer", "1.1");

        return responseDocument;
    }
