Please refere this

XmlMapper xmlMapper = new XmlMapper();

String xml= FileUtils.readFileToString(new File("test_4.xsd.xml"),Charset.defaultCharset());

JsonNode node = xmlMapper.readTree(xml.getBytes());

ObjectMapper jsonMapper = new ObjectMapper();

String json = jsonMapper.writeValueAsString(node);

System.out.println(json);
