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
