xml 和json互转工具

 工具1

有个问题会导致springboot返回捕获的异常编程xml格式

 import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import org.json.JSONObject;
import org.json.XML;
import org.w3c.dom.Document;import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import java.io.ByteArrayInputStream;
import java.io.InputStream;public class XmlJsonConverter {private static final ObjectMapper objectMapper = new ObjectMapper(); // JSON处理private static final XmlMapper xmlMapper = new XmlMapper(); // XML处理// JSON转XMLpublic static String jsonToXml(String json) throws Exception {// 将JSON转换为MapObject jsonObj = objectMapper.readValue(json, Object.class);// 将Map转换为XMLreturn xmlMapper.writeValueAsString(jsonObj);}// XML转JSONpublic static String xmlToJson(String xml) throws Exception {// 将XML转换为MapObject xmlObj = xmlMapper.readValue(xml, Object.class);// 将Map转换为JSONreturn objectMapper.writeValueAsString(xmlObj);}// 将XML字符串转换为XML文档对象private static Document toXmlDocument(String xml) throws Exception {DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();DocumentBuilder builder = factory.newDocumentBuilder();InputStream inputStream = new ByteArrayInputStream(xml.getBytes("UTF-8"));return builder.parse(inputStream);}// 将XML文档对象转换为JSON字符串public static String xmlDocumentToJson(Document doc) throws Exception {// XML文档转换为Map对象Object xmlObj = xmlMapper.readValue(xmlMapper.writeValueAsString(doc), Object.class);// Map转换为JSONreturn objectMapper.writeValueAsString(xmlObj);}// 测试代码public static void main (String[] args) {try {// JSON 转 XMLString json = "{\"name\":\"John\", \"age\":30}";String xml = jsonToXml(json);System.out.println("JSON to XML: \n" + xml);// XML 转 JSONString xmlStr = "<person><name>John</name><age>30</age></person>";String jsonResult = xmlToJson(xmlStr);System.out.println("XML to JSON: \n" + jsonResult);}

      <dependency><groupId>org.json</groupId><artifactId>json</artifactId><version>20210307</version></dependency>import org.json.JSONObject;
import org.json.XML;public class XmlJsonConverter {public static String jsonToXml(String json) {JSONObject jsonObject = new JSONObject(json);return XML.toString(jsonObject);}public static String xmlToJson(String xml) {JSONObject jsonObject = XML.toJSONObject(xml);return jsonObject.toString();}
