一、场景

在对接第三方接口时，由于接口返回的并不是常见的Json，而是XML，所以需要将XML转为Json，方便后续处理

二、工具类

package com.xxx.util;import org.apache.commons.lang.StringUtils;
import org.dom4j.Document;
import org.dom4j.Element;
import org.dom4j.io.SAXReader;import java.io.ByteArrayInputStream;
import java.util.List;/*** @author hcs* * @date 2024/1/19 10:55*/
public class XmlConverToJsonUtil {/*** 将xml转为json* * @param xml* @return*/public static com.alibaba.fastjson.JSONObject xmlConversionToJSON(String xml) {System.out.println("要转换的XML：\n" + xml);if (StringUtils.isBlank(xml)) {return null;}Document document = null;Element root = null;List<Element> elementList = null;List<Element> parantList = null;List<Element> childList = null;SAXReader reader = null;try {reader = new SAXReader();try {document = reader.read(new ByteArrayInputStream(xml.getBytes(Constant.default_encoding)));} catch (Exception e) {e.printStackTrace();return null;}root = document.getRootElement();elementList = root.elements();com.alibaba.fastjson.JSONObject map = new com.alibaba.fastjson.JSONObject();for (Element e : elementList) {String strName = e.getName();//map.put(strName, e.getText());map.put(strName, getElementValue(e, new com.alibaba.fastjson.JSONObject()));}return map;} catch (Exception e) {e.printStackTrace();} finally {document = null;root = null;if (elementList != null) {elementList.clear();}elementList = null;if (parantList != null) {parantList.clear();}parantList = null;if (childList != null) {childList.clear();}childList = null;reader = null;}return null;}/*** 遍历，获取元素值* * @param e* @param map* @return*/private static Object getElementValue(Element e, com.alibaba.fastjson.JSONObject map){List<Element> elements = e.elements();if (elements == null || elements.size() < 1) {return e.getText();} else {for (Element element : elements) {List elements2 = element.elements();if (elements2 == null || elements2.size() < 1) {map.put(element.getName(), element.getText());} else {map.put(element.getName(), getElementValue(element, new com.alibaba.fastjson.JSONObject()));}}return map;}}
}

三、测试类

package com.xxx;import com.xxx.util.XmlConverToJsonUtil;public class XmlTest {public static void main(String[] args) {String xmlStr = "<USER_INFO>\n" +"\t<NAME>张三</NAME>\n" +"\t<COMPANY>XXX股份有限公司</COMPANY>\n" +"\t<AUDIT_STATUS>3</AUDIT_STATUS>\n" +"\t<REGISTRANT>张三</REGISTRANT>\n" +"\t<PHONE_NUMBER>12345678901</PHONE_NUMBER>\n" +"\t<MAILBOX></MAILBOX>\n" +"\t<USER_GUID>eee-ddd-ccc-bbb-aaa</USER_GUID>\n" +"\t<SOURCE_APP_CODE>AAA</SOURCE_APP_CODE\n" +"\t><EXPERT_GRADE></EXPERT_GRADE>\n" +"</USER_INFO>";System.out.println("\n转为JSON对象：\n" + XmlConverToJsonUtil.xmlConversionToJSON(xmlStr));}
}
