这期内容当中小编将会给大家带来有关Java中怎么将xml转换为Json，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。
public class XmlToJsonUtils { private static Log log = LogFactory.getLog(Xml2JsonUtils.class); public static String xml2json(String xml) { //读取Xml文件 StringReader input = new StringReader(xml); StringWriter output = new StringWriter(); //开启自动配置 JsonXMLConfig config = new JsonXMLConfigBuilder().autoArray(true).autoPrimitive(true).prettyPrint(true).build(); try { //输入流事件 XMLEventReader reader = XMLInputFactory.newInstance().createXMLEventReader(input); XMLEventWriter writer = new JsonXMLOutputFactory(config).createXMLEventWriter(output); writer.add(reader); reader.close(); writer.close(); } catch (Exception e) { e.printStackTrace(); } finally { try { output.close(); input.close(); } catch (IOException e) { e.printStackTrace(); } } //json特殊格式 需要去除特殊符号，并保证源xml文件能符合要求 否则转换失败 return output.toString().replace("@", "").replace("#", "").replace("\"{", "{").replace("}\"", "}").replace("\\", ""); } }
demo测试
public static void main(String[] args) throws Exception { StopWatch stopWatch = new StopWatch(); stopWatch.start(); String text = FileUtils.readFileToString(new File("F:\\pom.xml"), "UTF-8"); System.out.println(Xml2JsonUtils.xmlTojson(text)); stopWatch.stop(); System.out.println("用时"+stopWatch.getTotalTimeMillis()+"ms"); }
控制台输出
