jsonXML格式化核心代码

json格式化：

依赖：

    com.jayway.jsonpath
    json-path
    2.6.0
    compile

string text = "{\"data\":{\"result\":true},\"path\":null,\"msgCode\":200,\"message\":\"请求成功\"}";
String s = JsonFormatter.prettyPrint(text);

xml格式化：

依赖：import org.xml.sax.InputSource;

调用：
String xml = xmlFormat(text, 4, false);

/**
 * @Description 格式化xml
 * @param xmlString xml内容
 * @param indent 向前缩进多少空格
 * @param ignoreDeclaration 是否忽略描述
 * @return 格式化后的xml
 */
public static String xmlFormat(String xmlString, int indent, boolean ignoreDeclaration) throws Exception{
    try {
        InputSource src = new InputSource(new StringReader(xmlString));
        Document document = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(src);
        TransformerFactory transformerFactory = TransformerFactory.newInstance();
        transformerFactory.setAttribute("indent-number", indent);
        Transformer transformer = transformerFactory.newTransformer();
        transformer.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
        transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, ignoreDeclaration ? "yes" : "no");
        transformer.setOutputProperty(OutputKeys.INDENT, "yes");
        Writer out = new StringWriter();
        transformer.transform(new DOMSource(document), new StreamResult(out));
        return out.toString();
    } catch (Exception e) {
        throw new Exception(e);
    }
}
