public static String json2xml(String json) {

StringReader input = new StringReader(json);

StringWriter output = new StringWriter();

JsonXMLConfig config = new JsonXMLConfigBuilder().multiplePI(false).repairingNamespaces(false).build();

try {

XMLEventReader reader = new JsonXMLInputFactory(config).createXMLEventReader(input);

XMLEventWriter writer = XMLOutputFactory.newInstance().createXMLEventWriter(output);

writer = new PrettyXMLEventWriter(writer);

writer.add(reader);

reader.close();

writer.close();

} catch (Exception e) {

e.printStackTrace();

} finally {

try {

output.close();

input.close();

} catch (IOException e) {

e.printStackTrace();

}

}

2 当然网上很多都是用：

XMLSerializer serializer = new XMLSerializer();

JSON jsonObject = JSONSerializer.toJSON(json);

return serializer.write(jsonObject);

这种方式转换的，需要的依赖：
