I have been searching in internet for a while to get a API that convert json into tabular format. I don't have any code which I tried. Please direct me if you have any idea about it.
Eg : Json
{"name":"rinu","age":"14","Phone":[{"countryCode":91,"number":"99862656"},{"countryCode":91,"number":"675432"}],"OtherDetails":[{"Active":true}]}
Output can be(with any separated)
rinu|14|91|99862656|true
rinu|14|91|675432|true
I don't want any ready-made stuff, If I get anything similar to this, I can re-write it.
You might need this:

ObjectMapper mapper = new ObjectMapper();
try {
Example example = mapper.readValue(new File("d:\\user.json"),
Example.class);
StringBuilder builder = new StringBuilder();
int i = 0;
for (Phone phone : example.getPhone()) {
builder.append(example.getName()).append("|");
builder.append(example.getAge()).append("|");
builder.append(phone.getCountryCode()).append("|")
.append(phone.getNumber()).append("|")
.append(example.getOtherDetails().get(i).getActive())
.append("|");
builder.append("\n");
}
File file = new File("d:\\user.txt");
// if file doesnt exists, then create it
if (!file.exists()) {
file.createNewFile();
}
FileWriter fw = new FileWriter(file.getAbsoluteFile());
BufferedWriter bw = new BufferedWriter(fw);
bw.write(builder.toString());
bw.close();
} catch (IOException e) {
e.printStackTrace();
}

{"name":"rinu","age":"14","Phone":[{"countryCode":91,"number":"99862656"},{"countryCode":91,"number":"675432"}],"OtherDetails":[{"Active":true}]}
I tried the library json2flat with the json
{"name":"rinu","age":"14","Phone":[{"countryCode":91,"number":"99862656"},{"countryCode":91,"number":"675432"}],"OtherDetails":[{"Active":true}]}
it gives a CSV like ::
rinu|14|91|99862656|
rinu|14|91|675432 |
rinu| | | |true
But if you tweak the json a little bit like ::
{"name":"rinu","age":"14","Phone":[{"countryCode":91,"number":"99862656","Active":true},{"countryCode":91,"number":"675432","Active":true}]}
it gives the csv exactly as you require.
rinu|14|91|99862656|true
rinu|14|91|675432|true
Give it a try. After all the solution depends upon how the user wants to interpret the json.

I am creating a REST API from java where I am returning an object list as follows:
#Path("/order")
public class OrderService implements IService
{
#Override
public Response get()
{
List<DataObj> list = new ArrayList<>();
List<SubDataObj> subList = new ArrayList<>();
subList.add(new SubDataObj("1"));
GenericEntity<List<DataObj>> entity;
list.add(new DataObj("A", "22", TestEnum.test1, DateTime.now(), subList));
list.add(new DataObj("B", "23", TestEnum.test2, DateTime.now(), subList));
entity = new GenericEntity<List<DataObj>>(list){};
return Response.ok(entity).build();
}
}
Here the service returns the Response fine when not using the subList, which is a object list within the DataObj class. However, when I am using it, i get an error as:
SEVERE: MessageBodyWriter not found for media type=application/json, type=class java.util.ArrayList, genericType=java.util.List<dyno.scheduler.restservice.DataObj>.
Here are the DataObj and the SubDataObj classes:
#XmlRootElement

{
private String name;
private String age;
private TestEnum enumVal;
private DateTime currentDate;
private List<SubDataObj> subData;
public DataObj(String name, String age, TestEnum enumVal, DateTime currentDate, List<SubDataObj> subData)

this.age = age;
this.enumVal = enumVal;

this.subData = subData;

{
return subData;
}
/**
* #param subData the subData to set
*/
public void setSubData(List<SubDataObj> subData)
{
this.subData = subData;
}
}
DataSubObj class:
class SubDataObj
{
private String subId;
public SubDataObj(String subId)
{
this.subId = subId;
}
/**
* #return the subId
*/
public String getSubId()
{
return subId;
}
/**
* #param subId the subId to set
*/
public void setSubId(String subId)
{
this.subId = subId;
}
}
I tried adding #XmlRootElement annotation to my SubDataObj class as well, which didn't work.
Any help would be appreciated!

My intention is to build a class to get the items in the response and use them in my Java Android application. The problem is that the first item of the response array is a number and not an object like the next items. So when I parse it with Gson it gives me the error:

Is there any way to make it work? I don't have access to the API server so i cant change how the result is displayed. To generate the class i used http://www.jsonschema2pojo.org/ but i was able to generate it only by removing the counter from the response.
The wrapper class VKSongApi:
public class VKSongApi {
private List<Response> response = new ArrayList<Response>();
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
/**
*
* #return
* The response
*/
public List<Response> getResponse() {
return response;
}
/**
*
* #param response
* The response
*/
public void setResponse(List<Response> response) {
this.response = response;
}
public Map<String, Object> getAdditionalProperties() {
return this.additionalProperties;
}
public void setAdditionalProperty(String name, Object value) {
this.additionalProperties.put(name, value);
}
}
The retrofit interface class is:
public interface VKApi {
#GET("/method/audio.search")
Call<VKSongApi> search(#Query("q") String query, #Query("access_token") String token);
}
Then in the MainActivity i do:
public static final String BASE_URL = "https://api.vk.com/method/";
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.build();
VKApi apiService =
retrofit.create(VKApi.class);
And call the method from the MainActivity with:
Call<VKSongApi> call = apiService.search("test","fff9ef502df4bb10d9bf50dcd62170a24c69e98e4d847d9798d63dacf474b674f9a512b2b3f7e8ebf1d69");
call.enqueue(new Callback<VKSongApi>() {
#Override
public void onResponse(Call<VKSongApi> call, Response<VKSongApi> response) {
int statusCode = response.code();
VKSongApi song = response.body();
Log.d(TAG,response.message());
}
#Override
public void onFailure(Call<VKSongApi> call, Throwable t) {
//Here the error occurs com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was NUMBER at line 1 column 20 path $.response[0]
Log.d(TAG,"Failure");
}
});
I solved by parsing manually the response using a custom deserializer class
firstly i have trouble with creating database,then i want to put my received huge json datas(i converted json to java model by GsonBuilder and i saw all the datas in my entity[] list which made from ReceivedEntityModel class) to database,but i failed at first steps.it never creates my columns,so that after insertion there is 0 rowcount:(, i read all those answers about this topic and they didn't help me at all.I'm stuck.Anyone can help??

this is Setup.java,fetchEntities(),AddNewEntity() functions are calling from there.Gson Builder make me a model.And the i call AddNewEntity()

Where are the column names defined?
The DefaultDimension2 column is not created with the intended name
in your table, because you forgot a space here:
+ DefaultDimension2 + "INTEGER, "
It must be
+ DefaultDimension2 + " INTEGER, "
So, supposing that the DefaultDimension2 column name is defined as
public String DefaultDimension2 = "DefaultDimension2";
it is actually created as "DefaultDimension2INTEGER, " instead of "DefaultDimension2 INTEGER, "
It's really a common mistake, mostly due to hurry.
Can anybody say where I am doing wrong. I have json like that

So I'm using ObjectMapper.readValue(jsontext, responseclass)
JSONObject object = new JSONObject(JsonString);
JsonString = "";
Iterator<String> keys= object.keys();
while (keys.hasNext()){
String keyValue = (String)keys.next();
JsonString= JsonString+ object.getString(keyValue);
}
JsonString= JsonString.substring(1, JsonString.length()-1);
Object response = ObjectMapper.readValue(JsonString, ShardsResponse.class);
At the last I am getting out of START_ARRAY token. Please anybody tell me what's wrong.
Cause I'm trying so much things, but I never find the solution.
How can I fix it.
Your json string is correct, but not for the object you expect, as someone mentioned already, you need to use a List

Edit:
If you expect a ShardsResponse back, your json string should look like this:
{"shards":[{"locales":["foo3"],"name":"foo","hostname":"foo4","slug":"foo2","region_tag":"foo5"},{"locales":["foo3"],"name":"foo","hostname":"foo4","slug":"foo2","region_tag":"foo5"},{"locales":["foo3"],"name":"foo","hostname":"foo4","slug":"foo2","region_tag":"foo5"},{"locales":["foo3"],"name":"foo","hostname":"foo4","slug":"foo2","region_tag":"foo5"}]}
Easiest way to figure out what the json will look like is to dump it out:
ShardsResponse sr = new ShardsResponse(list);
String srString = mapper.writeValueAsString(sr);
System.out.println("srString: " + srString );
Edit:
Adding additional Classes for clarity:
ShardsResponses.java
import java.util.ArrayList;
import java.util.List;
public class ShardsResponse {
private List<Shards> shards = new ArrayList<Shards>();
public ShardsResponse() { }
public ShardsResponse( List<Shards> shards)
{
this.shards = shards;
}
public List<Shards> getShards() {
return shards;
}
public void setShards(List<Shards> shards) {
this.shards = shards;
}
public void printDebug()
{
for ( Shards s : shards)
{
s.printDebug();
System.out.println("");
}
}
}
Shards.java:
import java.util.List;
public class Shards {
private List<String> locales;
private String name;
private String hostname;
private String slug;
private String region_tag;
public List<String> getLocales() {
return locales;
}
public void setLocales(List<String> locales) {
this.locales = locales;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getHostname() {
return hostname;
}
public void setHostname(String hostname) {
this.hostname = hostname;
}
public String getSlug() {
return slug;
}
public void setSlug(String slug) {
this.slug = slug;
}
public void printDebug()
{
System.out.println("name: " + name);
System.out.println("hostname: " + hostname);
System.out.println("slug: " + slug);
System.out.println("region_tag: " + region_tag);
for ( String s : locales )
{
System.out.println("Locals: " + locales);
}
}
public String getRegion_tag() {
return region_tag;
}
public void setRegion_tag(String region_tag) {
this.region_tag = region_tag;
}
}
you have an jsonArray but you are trying to parse a jsonObject. change your method to return a list of objects instead of one object.
