Json to XML – Java setting

Remark : Json 형식을 XML 로 변경

1.Jackson ObjectMapper 사용


import java.io.IOException;
import java.io.StringWriter;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import com.fasterxml.jackson.dataformat.xml.ser.ToXmlGenerator;
public class SimpleTesting{
    public static void main(String[] args) throws IOException{
        final String jsonStr = "{\"name\":\"JSON\",\"integer\":1,\"double\":2.0,\"boolean\":true,\"nested\":{\"id\":42},\"array\":[1,2,3]}";
        ObjectMapper jsonMapper = new ObjectMapper()
                     .configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false);;
        JsonNode node = jsonMapper.readValue(jsonStr, JsonNode.class);
        XmlMapper xmlMapper = new XmlMapper();
                xmlMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
                xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, true);
                xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_1_1, true);
        StringWriter sw = new StringWriter();
        xmlMapper.writeValue(sw, node);
        System.out.println(sw.toString());
    }
}

import java.io.IOException;

import java.io.StringWriter;

import com.fasterxml.jackson.databind.JsonNode;

import com.fasterxml.jackson.databind.ObjectMapper;

import com.fasterxml.jackson.databind.SerializationFeature;

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

import com.fasterxml.jackson.dataformat.xml.ser.ToXmlGenerator;

public class SimpleTesting{

public static void main(String[] args) throws IOException{

final String jsonStr = "{\"name\":\"JSON\",\"integer\":1,\"double\":2.0,\"boolean\":true,\"nested\":{\"id\":42},\"array\":[1,2,3]}";

ObjectMapper jsonMapper = new ObjectMapper()

.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,false);;

JsonNode node = jsonMapper.readValue(jsonStr, JsonNode.class);

XmlMapper xmlMapper = new XmlMapper();

xmlMapper.configure(SerializationFeature.INDENT_OUTPUT, true);

xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, true);

xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_1_1, true);

StringWriter sw = new StringWriter();

xmlMapper.writeValue(sw, node);

System.out.println(sw.toString());

}

2.Gson 사용

Spring


package com.example.demo;

import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;
import com.fasterxml.jackson.dataformat.xml.XmlMapper;
import com.fasterxml.jackson.dataformat.xml.ser.ToXmlGenerator;

import com.google.gson.GsonBuilder;
import com.google.gson.JsonElement;
import com.google.gson.JsonParser;

import org.apache.catalina.LifecycleException;
import org.json.simple.JSONObject;
import org.springframework.boot.autoconfigure.SpringBootApplication;

import java.io.*;
import java.net.HttpURLConnection;

import java.net.URL;
import service.SimpleRead;

import vo.JsonNode;

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) throws IOException, LifecycleException {

        //SpringApplication.run(DemoApplication.class, args);
        DemoApplication demo = new DemoApplication();

        JSONObject sJson = demo.TestJsonRead("TestData.json"); //class 정의

        GsonBuilder gsonBuilder = new GsonBuilder();
        gsonBuilder.serializeNulls();
        Gson gson = gsonBuilder.create();

        try {

            JsonNode node =gson.fromJson(sJson.toJSONString(), JsonNode.class);

            XmlMapper xmlMapper = new XmlMapper();
            xmlMapper.configure(SerializationFeature.INDENT_OUTPUT, true);
            xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_DECLARATION, true);
            xmlMapper.configure(ToXmlGenerator.Feature.WRITE_XML_1_1, true);
            StringWriter sw = new StringWriter();
            xmlMapper.writeValue(sw, node);
            System.out.println(sw.toString());


            } catch (Exception e) {

                throw new RuntimeException("Unexpected error during parsing body param.", e);
            }

        System.out.println("ok");
    }
