Java实现JSON到XML的转换

import com.google.gson.Gson;
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;
import com.google.gson.stream.JsonWriter;

import java.io.StringWriter;
import java.io.Writer;

public class JsonToXmlConverter {
    public static void main(String[] args) {
        String jsonString = "{\"name\":\"John\", \"age\":30, \"city\":\"New York\"}";
        String xmlString = convertJsonToXml(jsonString);
        System.out.println(xmlString);
    }

    public static String convertJsonToXml(String jsonString) {
        Gson gson = new Gson();
        JsonElement jsonElement = JsonParser.parseString(jsonString);
        Writer writer = new StringWriter();
        JsonWriter jsonWriter = new JsonWriter(writer);
        jsonWriter.setIndent("  ");
        gson.toJson(jsonElement, jsonWriter);
        return writer.toString();
    }
}
