在Java中将JSON字符串转换为XML字符串

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

public class JsonToXmlConverter {
    public static void main(String[] args) {
        try {
            // JSON字符串
            String json = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";

            // 创建ObjectMapper对象
            ObjectMapper objectMapper = new ObjectMapper();

            // 将JSON字符串转换为Java对象
            Object jsonObject = objectMapper.readValue(json, Object.class);

            // 创建XmlMapper对象
            XmlMapper xmlMapper = new XmlMapper();

            // 将Java对象转换为XML字符串
            String xml = xmlMapper.writeValueAsString(jsonObject);

            System.out.println(xml);
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}
