对Java中Json与XML之间相互转换的程序进行了改进

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;

public class JsonXmlConverter {
    private static final ObjectMapper jsonMapper = new ObjectMapper();
    private static final XmlMapper xmlMapper = new XmlMapper();

    public static String jsonToXml(String json) throws Exception {
        Object jsonObject = jsonMapper.readValue(json, Object.class);
        return xmlMapper.writeValueAsString(jsonObject);
    }

    public static String xmlToJson(String xml) throws Exception {
        Object xmlObject = xmlMapper.readValue(xml, Object.class);
        return jsonMapper.writeValueAsString(xmlObject);
    }

    public static void main(String[] args) throws Exception {
        String json = "{\"name\":\"John\", \"age\":30}";
        String xml = "<Person><name>John</name><age>30</age></Person>";

        String convertedXml = jsonToXml(json);
        System.out.println("Json to XML:");
        System.out.println(convertedXml);

        String convertedJson = xmlToJson(xml);
        System.out.println("XML to Json:");
        System.out.println(convertedJson);
    }
}
