Getting null from POJO after using JACKSON ObjectMapper

Getting null from POJO after using JACKSON ObjectMapper - java

I'm struggling whit this problem for a while and can't find a solution.
My intention is to retrieve a POJO from the following JSON using Jackson:
{
"date": "2018-11-27",
"rates": {
"BGN": 1.9558,
"CAD": 1.5018,
"BRL": 4.4011,
"HUF": 324.06,
"DKK": 7.4617,
"JPY": 128.66,
"ILS": 4.2215,
"TRY": 5.9313,
"RON": 4.6583,
"GBP": 0.88748,
"PHP": 59.439,
"HRK": 7.4275,
"NOK": 9.7325,
"USD": 1.1328,
"MXN": 23.1784,
"AUD": 1.5631,
"IDR": 16410.59,
"KRW": 1279.17,
"HKD": 8.8679,
"ZAR": 15.632,
"ISK": 141,
"CZK": 25.914,
"THB": 37.371,
"MYR": 4.7498,
"NZD": 1.6647,
"PLN": 4.2902,
"SEK": 10.2823,
"RUB": 75.6401,
"CNY": 7.8708,
"SGD": 1.5582,
"CHF": 1.1309,
"INR": 80.162
},
"base": "EUR"
}
I solved it with the following code:
public class JsonToPojo {
private static final String URL_LATEST = "https://api.exchangeratesapi.io/latest";
public static String getJson() {
try {
URL url = new URL(URL_LATEST);
HttpURLConnection urlConnection = (HttpURLConnection)url.openConnection();
urlConnection.setRequestMethod("GET");
BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
String inputLine;
StringBuffer response = new StringBuffer();
while ((inputLine = bufferedReader.readLine()) != null) {
System.out.println(inputLine);
response.append(inputLine);
}
bufferedReader.close();
urlConnection.disconnect();
return response.toString();
} catch (IOException e) {
e.getStackTrace();
return null;
}
}
}
This is my POJO:
public class Currency {
private String date;
private Rates rates;
private String base;
public String getBase() {
return base;
}
public void setBase(String base) {
this.base = base;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public Rates getRates() {
return rates;
}
public void setRates(Rates rates) {
this.rates = rates;
}
}
Class using ObjectMapper:
public class CurrencyService {
public static Currency getLatestCurrency(){
try {
ObjectMapper mapper = new ObjectMapper();
Currency currency = mapper.readValue(JsonToPojo.getJson(), Currency.class);
return currency;
}catch (IOException e){
e.getStackTrace();
return null;
}
}
}
When I'm trying to call the get method on my POJO object, I'm getting a NullPointException, so something is wrong with databinding.

I've checked your code locally, and have got it working. I didn't have a Rates class, so I used a Map instead (to map the name, with the rate (float)):
import java.util.Map;
public class Currency {
private String date;
private Map<String, Float> rates;
private String base;
public String getBase() {
return base;
}
public void setBase(String base) {
this.base = base;
}
public String getDate() {
return date;
}
public void setDate(String date) {
this.date = date;
}
public Map<String, Float> getRates() {
return rates;
}
public Float getSingleRate(String rateKey) {
if (rates.containsKey(rateKey)) {
return rates.get(rateKey);
}
return 0.0F;
}
public void setRates(Map<String, Float> rates) {
this.rates = rates;
}
}
I have added the following main() method to your JSonToPojo class:
public static void main(String[] args) {
ObjectMapper mapper = new ObjectMapper();
Currency currency = new Currency();
String jsonStr = getJson();
try {
currency = mapper.readValue(jsonStr, Currency.class);
} catch (IOException e) {
e.printStackTrace();
}
System.out.println(jsonStr);
System.out.println(currency.getSingleRate("BGN"));
System.out.println("finished");
}
Running the main() method, produces the following output (I have used [snip] instead of printing out all the JSon (twice)):
{"date":"2018-11-27","rates": {"BGN":1.9558, [snip] }
{"date":"2018-11-27","rates": {"BGN":1.9558, [snip] }
1.9558
finished
The output for "BGN" is:
1.9558

You can refer to http://www.jsonschema2pojo.org/ to get the correct pojo for your json.
Below is the one I created (moderatley modified)
You can replace like Object date with Date date and so on. If it doesn't work than there is probably some error in your POJO
import com.fasterxml.jackson.annotation.JsonProperty;
import java.util.HashMap;
import java.util.Map;
import com.fasterxml.jackson.annotation.JsonAnyGetter;
import com.fasterxml.jackson.annotation.JsonAnySetter;
import com.fasterxml.jackson.annotation.JsonIgnore;
public class Example {
#JsonProperty("date")
private Object date;
#JsonProperty("rates")
private Object rates;
#JsonProperty("base")
private Object base;
#JsonIgnore
private Map<String, Object> additionalProperties = new HashMap<String, Object>();
#JsonProperty("date")
public Object getDate() {
return date;
}
#JsonProperty("date")
public void setDate(Object date) {
this.date = date;
}
#JsonProperty("rates")
public Object getRates() {
return rates;
}
#JsonProperty("rates")
public void setRates(Object rates) {
this.rates = rates;
}
#JsonProperty("base")
public Object getBase() {
return base;
}
#JsonProperty("base")
public void setBase(Object base) {
this.base = base;
}
#JsonAnyGetter
public Map<String, Object> getAdditionalProperties() {
return this.additionalProperties;
}
#JsonAnySetter
public void setAdditionalProperty(String name, Object value) {
this.additionalProperties.put(name, value);
}
#Override
public String toString() {
return "date:" + date.toString() +
",\nrates:" + rates.toString() +
",\nbase: " + base.toString();
}
}
And here is the driver class in which you can read the object and pass in the user defined file path ( i have set it to "test-json.json"). You can update this with your local file path address.
import com.fasterxml.jackson.databind.ObjectMapper;
import java.io.IOException;
import java.nio.file.Files;
import java.nio.file.Paths;
import java.util.stream.Collectors;
import java.util.stream.Stream;
public class Main {
public static void main(String... args){
Main main = new Main();
Example example = main.readObjectDataFromJsonFile(Example.class,"test-json.json");
System.out.println(example);
}
public <T> T readObjectDataFromJsonFile(Class<T> clazz, String jsonFilePath) {
T populatedObject = null;
try {
ObjectMapper objectMapper = new ObjectMapper();
String objectJson = "";
Stream<String> lines = Files.lines(Paths.get(jsonFilePath));
objectJson = lines.collect(Collectors.joining());
lines.close();
populatedObject = objectMapper.readValue(objectJson, clazz);
} catch (IOException ioException) {
System.out.println("Exception in reading json file");
System.out.println(ioException.getMessage());
}
return populatedObject;
}
}

you can use
mapper.configure(MapperFeature.ACCEPT_CASE_INSENSITIVE_PROPERTIES, true);
without any change to your Pojos, but I had to add MXN as a property to Rates class. But ideal way to handle this is having a Map for the rates. Because it can change any time as I understood, either way its easier for access. So change Currency class as follows.
public class Currency {
private String date;
private Map<String, Float> rates;
private String base;
// getters and setters
}
access exchange rates as getRates().get('MXN') // returns value.

Can't get all data from my model class using Retrofit

I need a little help, I'd already run out of ideas, tried to run this program out for two days, but I'm literally out of any ideas. So, I want from program to:
Display actual currency exchange
In another activity, the program should have a possibility to calculate currencies (let's say, we have a String with value "CZK" so the program should get from Model class currency value, to get that possibility to calculate the currencies, and here's the problem, I can't get those values. Actually, I can display it, but I want to call methods like getCZK(); because there are the actual values of those currencies. To be more accurate, ill try to explain it in other way: Let's say, the base currency is EUR, user selected option, that he want converse EUR to CZK, so program should have a String based of user choice (in this case it's String with value "CZK") now, program should search in switch case for value such as CZK, when it will find it, it should pass method like getCZK(); to suitable variable, to make conversion possible. I hope I explained it well to you guys.

these lines here
#SerializedName("rates")
private Map<String, Double> rates;
Should instead be like this
#SerializedName("rates")
private Rates rates;
Then in the onResponse you can get each of the values from the response like
Log.d("check", "CAD: "+response.body().getRates().getCAD());
Log.d("check", "GBP: "+response.body().getRates().getGBP());
Which returns
2019-05-14 17:27:16.015 6816-6816/com.test.testing D/check: CAD: 1.5117
2019-05-14 17:27:16.015 6816-6816/com.test.testing D/check: GBP: 0.86723
Does this answer your question?

My Problem is that how can send the data in model.
My Model Should contain data Like id,displayName,amountMin,eta,image,amountMax

First of all you need to make two different models for category and ride_estimate.Because they both are in different loops. Also try this
for (j = 0; j < ride_estimate.length(); j++) {
Log.e("sushil", String.valueOf(j));
rideestimate = ride_estimate.getJSONObject(j);
distance = rideestimate.getString("distance");
amount_min = rideestimate.getString("amount_min");
amount_max = rideestimate.getString("amount_max");
category = rideestimate.getString("category");
OlaUberModel olaUberModel = new OlaUberModel(category, display_name, amount_min, eta, image, amount_max);
arrayList.add(olaUberModel);
}
May be this would helpful for you..
Thanks!

replace
eta = jsonObject.getString("eta");
by
int eta = jsonObject.getInt("eta");

On the basis of id of any cab type "prime" you can fetch image. what say

create some class as per your data

Now compile a library compile 'com.google.code.gson:gson:2.8.2'
then write few line to get your data fill in class
Gson gson = new Gson();
Example example = gson.fromJson(mainObj, Example.class);
Now you can try to fetch your categories like this
example.getCategories();

List of class objects from list of strings

I am getting data from gemfire
List<String> objects = restTemplate.getForObject(geodeURL+"/gemfire-api/v1/queries/adhoc?q=SELECT * FROM /region s",List.class);
which is like below:
[('price':'119','volume':'20000','pe':'0','eps':'4.22','week53low':'92','week53high':'134.4','daylow':'117.2','dayhigh':'119.2','movingav50day':'115','marketcap':'0','time':'2015-11-25 05:13:34.996'), ('price':'112','volume':'20000','pe':'0','eps':'9.22','week53low':'92','week53high':'134.4','daylow':'117.2','dayhigh':'119.2','movingav50day':'115','marketcap':'0','time':'2015-11-25 05:13:34.996'), ('price':'118','volume':'20000','pe':'0','eps':'1.22','week53low':'92','week53high':'134.4','daylow':'117.2','dayhigh':'119.2','movingav50day':'115','marketcap':'0','time':'2015-11-25 05:13:34.996')]

How do I create a List of StockInfo class object from the value I am getting from restTemplate.getForObject

I think you could just use:
List<StockInfo> objects = restTemplate.getForObject(geodeURL+"/gemfire-api/v1/queries/adhoc?q=SELECT * FROM /region s",List.class);
