Json is not extracted to Java POJO object

Json is not extracted to Java POJO object - java

I'm using rest-assured with Gson for testing when getting a response from the BE service I'm creating a POJO object that deserializes the JSON and creates and object, but for some reason all object fields are null, FYI I'm using the same practice at another API calls and it works, but in this case, it's not.

And do on, in order to create the java object I'm using this code:
OriginalDTO original = response.then().statusCode(200).extract().as(OriginalDTO.class);
but for some reason all OriginalDTO fields values are null.
what I need to fix in this code

I handled this with work around using
Gson gson = new GsonBuilder().create();
OriginalDTO original = gson.fromJson(response.body().asString(), OriginalDTO.class);
instead of
OriginalDTO original =response.then().statusCode(200).extract().as(OriginalDTO.class)

how I change the format of the json array that made by Repository.findAll() in spring boot

I want to change this json list to another format by putting the word "data" before the list and included in Parentheses like I the examples I put it down
the rest controller that I use
#CrossOrigin(origins = "http://localhost:8080")
#GetMapping("/users")
public List<User> getAllUsers() {
return userRepository.findAll();
}
the response is like that
[
{
"id": 1,
"firstName": "test",
"lastName": "test",
"email": "tt",
"createdAt": null,
"createdBy": "12",
"updatedAt": null,
"updatedBy": "12"
},
{
"id": 2,
"firstName": "test",
"lastName": "test",
"email": "tt",
"createdAt": null,
"createdBy": "12",
"updatedAt": null,
"updatedBy": "12"
}
]
I want to make it like that
{
"data": [
{
"id": 1,
"firstName": "test",
"lastName": "test",
"email": "tt",
"createdAt": null,
"createdBy": "12",
"updatedAt": null,
"updatedBy": "12"
},
{
"id": 2,
"firstName": "test",
"lastName": "test",
"email": "tt",
"createdAt": null,
"createdBy": "12",
"updatedAt": null,
"updatedBy": "12"
}
]
}

You can create another model class with `data property
public class UserData {
private List<User> data
// getters and setters
}
Then change the return type in the controller
#CrossOrigin(origins = "http://localhost:8080")
#GetMapping("/users")
public UserData getAllUsers() {
List<User> users = userRepository.findAll();
return new UserData(users);
}
Or if you don't want to create additional models, you can use Map<String, List<User>>
#CrossOrigin(origins = "http://localhost:8080")
#GetMapping("/users")
public Map<String, List<User>> getAllUsers() {
List<User> users = userRepository.findAll();
return Collections.singletonMap("data",users);
}

In the above JSONObject I want to replace key nullable with $nullable and localPart with $localPart etc. Can anyone help me with Java code.

I solved the problem with the following code:
import java.util.Iterator;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
public class ReplaceKeyInNestedJson {
public static void removeJSONField(JSONObject obj) throws JSONException {
obj.put("$nullable", obj.remove("nullable"));
obj.put("$localPart", obj.remove("localPart"));
obj.put("$prefix", obj.remove("prefix"));
obj.put("$precision", obj.remove("precision"));
obj.put("$name", obj.remove("name"));
obj.put("$namespace", obj.remove("namespace"));
obj.put("$scale", obj.remove("scale"));
Iterator<String> it = obj.keys();
while (it.hasNext()) {
String key = it.next();
Object childObj = obj.get(key);
if (childObj instanceof JSONArray) {
JSONArray arrayChildObjs = ((JSONArray) childObj);
int size = arrayChildObjs.length();
for (int i = 0; i < size; i++) {
removeJSONField(arrayChildObjs.getJSONObject(i));
}
}
if (childObj instanceof JSONObject) {
removeJSONField(((JSONObject) childObj));
}
}
}
public static void main(String[] args) {
String jsonStr = "{\n" + " \"nullable\": null,\n" + " \"localPart\": null,\n" + " \"prefix\": null,\n"
+ " \"precision\": null,\n" + " \"name\": \"Put_Location_Request\",\n" + " \"namespace\": null,\n"
+ " \"scale\": null,\n" + " \"unicode\": null,\n" + " \"type\": null,\n" + " \"maxLength\": null,\n"
+ " \"srid\": null,\n" + " \"subEntities\": [\n" + " {\n" + " \"nullable\": null,\n"
+ " \"localPart\": null,\n" + " \"prefix\": null,\n" + " \"precision\": null,\n"

+ " \"maxLength\": null,\n" + " \"srid\": null,\n" + " \"subEntities\": [{\n"

+ " \"localPart\": null,\n" + " \"prefix\": null,.............";
try {
JSONObject obj = new JSONObject(jsonStr);
removeJSONField(obj);
System.out.println(obj);
} catch (JSONException e) {
e.printStackTrace();
}
}}

If you are using faster.Jackson library you can solve like below:
import java.io.IOException;
import java.util.Iterator;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.node.ArrayNode;
import com.fasterxml.jackson.databind.node.ObjectNode;
public class ReplaceKeyInNestedJson2 {
private static final String FIELD_TYPE = "FieldType";
public static JsonNode removeJSONField(JsonNode obj) {
ObjectNode object = (ObjectNode) obj;
object.put("$kind", FIELD_TYPE);
object.set("$nullable", object.get("nullable"));
object.remove("nullable");
object.set("$localPart", object.get("localPart"));
object.remove("localPart");
object.set("$prefix", object.get("prefix"));
object.remove("prefix");
object.set("$precision", object.get("precision"));
object.remove("precision");
object.set("$name", object.get("name"));
object.remove("name");
object.set("$namespace", object.get("namespace"));
object.remove("namespace");
object.set("$scale", object.get("scale"));
object.remove("scale");
Iterator<String> it = obj.fieldNames();
while (it.hasNext()) {
String key = it.next();
JsonNode childObj = obj.get(key);
if (childObj.isArray()) {
ArrayNode arrayChildObjs = ((ArrayNode) childObj);
int size = arrayChildObjs.size();
for (int i = 0; i < size; i++) {
removeJSONField(arrayChildObjs.get(i));
}
}
if (childObj.isObject()) {
removeJSONField(((JsonNode) childObj));
}
}
return obj;
}
public static void main(String[] args) throws IOException {
try {
ObjectMapper mapper = new ObjectMapper();
JsonNode obj = mapper.readTree(StaticData.fieldsJson);
JsonNode result = removeJSONField(obj);
System.out.println(result);
} catch (Exception e) {
e.printStackTrace();
}
}
}

Use the below link or something similar to first create a Java object class to hold the data
http://www.jsonschema2pojo.org/
The use GsonConverterFactory with Retrofit to convert the object. Below link tells you how to add it
https://futurestud.io/tutorials/retrofit-2-adding-customizing-the-gson-converter

Create Pojo class and implementsSerializable. Use this class to get a response.
try this,
class pojo implements Serializable{
#SerializedName("name")
private String name;
public long getName() {
return name;
}
public void setId(String name) {
this.name = name;
}
}

"data": {
"hotels": [
{

}
]
}
}
}
}
My code:-
String getusertypestitlestring = jsonResult.getJSONObject("xyz").getJSONObject("response").getJSONArray("hotels").getJSONArray(0).getString(1);
:: i want to get userTypes>> title
:: i want to get bookings >> group >> code

Try this:
JSONArray userTypesArray = jsonResult.getJSONObject("xyx").getJSONObject("response").getJSONArray("hotels").getJSONObject(0).getJSONArray("userTypes");
for(int i =0 ; i< userTypesArray.length(); i++){
JSONObject userType = userTypesArray.getJSONObject(i);
System.out.println(userType.get("title"));
}

String getusertypestitlestring = jsonResult.getJSONObject("xyz").getJSONObject("response").getJSONArray("hotels").getJSONArray(0).getString(1);
Here it is not xyz, that is xyx

Make pojo of each Json Object in your Json String.
For Ex:
Make class POJO:
public class POJO {
XYX xyx;
public XYX getXyx() {
return xyx;
}
public void setXyx(XYX xyx) {
this.xyx = xyx;
}
}
Make class XYX:
public class XYX implements Serializable{
String version;
String datetime;
Response response;
Request request;
public String getVersion() {
return version;
}
public void setVersion(String version) {
this.version = version;
}
public String getDatetime() {
return datetime;
}
public void setDatetime(String datetime) {
this.datetime = datetime;
}
public Response getResponse() {
return response;
}
public void setResponse(Response response) {
this.response = response;
}
public Request getRequest() {
return request;
}
public void setRequest(Request request) {
this.request = request;
}
}
Make class Response:
class Response {
Status status;
List<Hotels> hotels;
public Status getStatus() {
return status;
}
public void setStatus(Status status) {
this.status = status;
}
public List<Hotels> getHotels() {
return hotels;
}
public void setHotels(List<Hotels> hotels) {
this.hotels = hotels;
}
}
Make Class Request :
class Request {
String method;
String key;
public String getMethod() {
return method;
}
public void setMethod(String method) {
this.method = method;
}
public String getKey() {
return key;
}
public void setKey(String key) {
this.key = key;
}
}
and for List
Make class Hotels:
class Hotels {
String id;
List<UserTypes> userTypes;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public List<UserTypes> getUserTypes() {
return userTypes;
}
public void setUserTypes(List<UserTypes> userTypes) {
this.userTypes = userTypes;
}
}
and make all other pojo classes and use Gson library to set data in your pojos :
POJO pojo = new Gson().fromJson(jsonResponse,POJO.class);
And read Data from pojo :
System.out.println(pojo.getXyx().getDatetime());
System.out.println(pojo.getXyx().getRequest().getKey());
System.out.println(pojo.getXyx().getResponse().getHotels().get(0).getUserTypes().get(0).getTitle());

You can easily use GSON instead of JSON. It's more comfortable to work with the GSON objects. More input is available at:

When trying to fetch this data, I use the following
RestTemplate restTemplate = new RestTemplate();
final IssueDTO[] responseEntity = restTemplate.getForObject("http://localhost:8080/im-access/api/issues", Embedded.class).getIssues();
and my Embedded class is this
#JsonIgnoreProperties(ignoreUnknown = true)
public class Embedded {
private IssueDTO[] issues;
public IssueDTO[] getIssues() {
return issues;
}
public void setIssues(IssueDTO[] issues) {
this.issues = issues;
}
}
However,I get a null pointer exception when trying to get the data.

It looks like your DTO structure is little off. When I generated your DTOs from http://www.jsonschema2pojo.org/ then I get a structure like below. I think you are missing one level of nesting in your DTO structure, thats why your deserializing is failing. So your code should like this,
final List<Issues> issues = restTemplate.getForObject(url,WrapperEmbedded.class).getEmbedded().getIssues();
Here is the trimmed version of DTOs, you can try yourself on http://www.jsonschema2pojo.org/ (make sure to select JSON as source type)
public class WrapperEmbedded {
#JsonProperty("_embedded")
private com.example.Embedded Embedded;
#JsonIgnore
private Map<String, Object> additionalProperties = new HashMap<String, Object> ();
//GETTERS AND SETTERS
}
#JsonInclude(JsonInclude.Include.NON_NULL)
#Generated("org.jsonschema2pojo")
#JsonPropertyOrder({
"issues"
})
public class Embedded {
#JsonProperty("issues")
private List<Issue> issues = new ArrayList<Issue>();

We Keep Coding

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

Json is not extracted to Java POJO object - java

I handled this with work around using Gson gson = new GsonBuilder().create(); OriginalDTO original = gson.fromJson(response.body().asString(), OriginalDTO.class); instead of OriginalDTO original =response.then().statusCode(200).extract().as(OriginalDTO.class)
