Consuming a third party RESTful API passing a parameter

Consuming a third party RESTful API passing a parameter - java

I need to consume a third party RESTful API. This is my controller class:
#Controller
public class BrokerController {
#RequestMapping(value = "/broker", method = RequestMethod.POST)
public #ResponseBody MyPojo brokers(#RequestBody BrokerRequest brokerRequest){
RestTemplate restTemplate = new RestTemplate();
final String uri = "http://www.nepalipaisa.com/Modules/MarketMovers/Services/MarketMoversServices.asmx/GetTopBrokers";
MyPojo myPojo = restTemplate.postForObject(uri,brokerRequest,MyPojo.class);
return myPojo;
}
}
Edited:- My pojo class:

The JSON iI need to consume, i.e the exact result given below:
{
"d": [
{
"__type": "SageFrame.MarketMovers.MarketInfo",
"RowTotal": 0,
"StockID": 0,
"CodedCompany": null,
"ClosingPrice": null,
"Amount": 0,
"PreviousClosing": 0,
"DifferenceRS": 0,
"Symbol": null,
"Price": 0,
"Diff": 0,
"PercentageDiff": 0,
"Volume": null,
"TotalTurnOverAmount": 109969058,
"FirmName": "Vision Securities Pvt. Ltd.",
"BrokerID": 0,
"BrokerCode": "34",
"TotalTransactions": 0,
"Traded": null,
"MaxPrice": null,
"MinPrice": null,

},
{
"__type": "SageFrame.MarketMovers.MarketInfo",
"RowTotal": 0,
"StockID": 0,

"Amount": 0,
"PreviousClosing": 0,
"DifferenceRS": 0,

"NoOfTransaction": 0,
"Purchase": 51927902,
"Sales": 52902587,
"Matching": 3049044
}
]
}
Currently when I send a POST request with two parameters
{
"offset":"1",
"limit":"2000"
}
I can get the result given above. Now I need to return the same result but through my own controller. The above controller returns MyPojo class with null value on every properties.

You can always try to put the results from the third party API into a Map.
Map results = restTemplate.postForObject(uri,brokerRequest, Map.class);
Or you can create a new pojo just for that third part API.
ThirdPartyPojo results = restTemplate.postForObject(uri,brokerRequest, ThirdPartyPojo.class);

Right now the issue is that your pojo MyPojo is not compatible with the response of 3rd party API.
Your pojo should be something like following.
-----------------------------------com.example.D.java-----------------------------------
package com.example;
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;
import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.annotation.JsonPropertyOrder;
public class D {
private String type;
private Integer rowTotal;
private Integer stockID;
private Object codedCompany;
private Object closingPrice;
private Integer amount;
private Integer previousClosing;
private Integer differenceRS;
private Object symbol;
private Integer price;
private Integer diff;
private Integer percentageDiff;
private Object volume;
private Integer totalTurnOverAmount;
private String firmName;
private Integer brokerID;
private String brokerCode;
private Integer totalTransactions;
private Object traded;
private Object maxPrice;
private Object minPrice;
private Object openingPrice;
private Object totalShare;
private Integer noOfTransaction;
private Integer purchase;
private Integer sales;
private Integer matching;
// Getter .. Setter//
}
-----------------------------------com.example.MyPojo.java-----------------------------------
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import com.fasterxml.jackson.annotation.JsonAnyGetter;
import com.fasterxml.jackson.annotation.JsonAnySetter;
import com.fasterxml.jackson.annotation.JsonIgnore;
import com.fasterxml.jackson.annotation.JsonInclude;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.annotation.JsonPropertyOrder;
public class Example {
#JsonProperty("d")
private List<D> d = null;
// Getter ... Setter
}
Or simply you can use Map.

This can be accomplished easily not even requiring you to provide custom mappings or whatever like that and guarantee that your controller wil provide the same response (not the same headers, though):
#RestController
final class Controller {
// Both RestTemplate and URI instances can be cached
private static final RestTemplate restTemplate = new RestTemplate();
private static final URI testUri = URI.create("http://www.nepalipaisa.com/Modules/MarketMovers/Services/MarketMoversServices.asmx/GetTopBrokers");
// I'm using GET just to simplify the testing using a web browser
#RequestMapping(method = GET, value = "/")
public void post(final ServletResponse response)
throws IOException {
// Create a POST request entity
final RequestEntity<?> requestEntity = new RequestEntity<>(getRequest(0, 10), POST, testUri);
// And send the request to the remote server
final ResponseEntity<Resource> responseEntity = restTemplate.exchange(requestEntity, Resource.class);
// Now just copy the response input stream to the output stream of this controller
try ( final InputStream inputStream = responseEntity.getBody().getInputStream() ) {
// Or provide HttpServletResponse via the controller method to be able to configure the response more accurately
StreamUtils.copy(inputStream, response.getOutputStream());
}
}
private static Object getRequest(final long offset, final long limit) {
final Map<String, Object> request = new HashMap<>();
request.put("offset", offset);
request.put("limit", limit);
return request;
}
}
The remote server can respond with a non-successful response code, so you can also have a custom controller advice to handle RestTemplate exceptions:
#ControllerAdvice
final class ExceptionControllerAdvice {
#ExceptionHandler(HttpServerErrorException.class)
#ResponseBody
public ResponseEntity<?> handleHttpServerErrorException(final HttpServerErrorException ex) {
return new ResponseEntity<Object>("Bad gateway: " + ex.getMessage(), BAD_GATEWAY);
}
}

Receive array of objects in JSON by Spring Boot RestApi Controller

I want to send array of objects like this to Spring REST Controller:
{
"measureList": [
{
"apiKey": "exampleKEY",
"stationId": "abcdef123",
"date": "2022-02-18T17:43:51.787535Z",
"temp": "20.5",
"humidity": "60.4",
"pressure": "1020.5",

},
{
"apiKey": "exampleKEY",

"date": "2022-02-18T17:43:53.254309Z",
"temp": "20.5",
"humidity": "60.4",
"pressure": "1020.5",
"pm25": "100.0",
"pm25Corr": "150.0",
"pm10": "90.0"
}
]
}
I have created NewMeausurePackageDto like this:
package com.weather.server.domain.dto;
import java.util.ArrayList;
import java.util.List;
public class NewMeasurePackageDto {
private ArrayList<NewMeasureDto> measureList;
public NewMeasurePackageDto(ArrayList<NewMeasureDto> measureList) {
this.measureList = measureList;
}
public NewMeasurePackageDto() {
}
public ArrayList<NewMeasureDto> getNewMeasureListDto() {
return measureList;
}
#Override
public String toString() {
return "NewMeasurePackageDto{" +
"measureList=" + measureList +
'}';
}
}
NewMeasureDto class:
package com.weather.server.domain.dto;
public class NewMeasureDto {
private String apiKey;
private String stationId;
private String date;
private String temp;
private String humidity;
private String pressure;
private String pm25;
private String pm10;
private String pm25Corr;
//station_id
public NewMeasureDto() {
}
private NewMeasureDto(Builder builder){
apiKey = builder.apiKey;
stationId = builder.stationId;
date = builder.date;
temp = builder.temp;
humidity = builder.humidity;
pressure = builder.pressure;
pm25 = builder.pm25;
pm10 = builder.pm10;
pm25Corr = builder.pm25Corr;
}
public String getApiKey() {
return apiKey;
}
public String getStationID() {
return stationId;
}
public String getDate() {
return date;
}
public String getTemp() {
return temp;
}
public String getHumidity() {
return humidity;
}
public String getPressure() {
return pressure;
}
public String getPm25() {
return pm25;
}
public String getPm10() {
return pm10;
}
public String getPm25Corr() {
return pm25Corr;
}
public static final class Builder {
private String apiKey;
private String stationId;
private String date;
private String temp;
private String humidity;
private String pressure;
private String pm25;
private String pm10;
private String pm25Corr;
public Builder() {
}
public Builder apiKey(String apiKey) {
this.apiKey = apiKey;
return this;
}
public Builder stationID(String stationId) {
this.stationId = stationId;
return this;
}
public Builder date(String date) {
this.date = date;
return this;
}
public Builder temp(String temp) {
this.temp = temp;
return this;
}
public Builder humidity(String humidity) {
this.humidity = humidity;
return this;
}
public Builder pressure(String pressure){
this.pressure = pressure;
return this;
}
public Builder pm25(String pm25){
this.pm25 = pm25;
return this;
}
public Builder pm10(String pm10){
this.pm10 = pm10;
return this;
}
public Builder pm25Corr(String pm25Corr){
this.pm25Corr = pm25Corr;
return this;
}
public NewMeasureDto build() {
return new NewMeasureDto(this);
}
}
}
And request mapping in RestController:
#PostMapping(value="/new-measure-package") //addStation id
public ResponseEntity<Void> newMeasure(#RequestBody NewMeasurePackageDto measureList){
//if api key is valid
return measureService.saveMeasurePackage(measureList.getNewMeasureListDto()) ? new ResponseEntity<>(HttpStatus.OK) :
new ResponseEntity<>(HttpStatus.BAD_REQUEST);
}
With this code all I got is error about null measureList in Service function when trying to iterate over the list. I tried changing #RequestBody to
List<NewMeasureDto> measureList, and to Map<String, NewMeasureDto> measureList but still measureList is null or empty.

Thanks to ShaharT suggestion I found the answer.
There was missing setter in NewMeasurePackageDto, the class should look like this:
package com.weather.server.domain.dto;
import java.util.ArrayList;
public class NewMeasurePackageDto {
private ArrayList<NewMeasureDto> measureList;
public NewMeasurePackageDto(ArrayList<NewMeasureDto> measureList) {
this.measureList = measureList;
}
public NewMeasurePackageDto() {
}
public ArrayList<NewMeasureDto> getMeasureList() {
return measureList;
}
public void setMeasureList(ArrayList<NewMeasureDto> measureList) {
this.measureList = measureList;
}
#Override
public String toString() {
return "NewMeasurePackageDto{" +
"measureList=" + measureList +
'}';
}
}
Conclusion is: when dealing with object of arrays in JSON, there must be setter method for variable storing list in DTO.

Output Spring Boot is reversed in Postman

My problem: when I do an #Post in Postman I get data back from the prices, but not kitten data.
I enter the following:
{
"name": "Frizzle",
"dateOfBirth": "2019-07-27",
"weight": 7.1,
"breed": "Birman",
"firstVaccination": "yes",
"secondVaccination": "yes",
"breedPrice": 8000,
"firstVaccinationPrice": 80.50,
"secondVaccinationPrice": 80.10
}
And this is what I get back in Postman:
{
"id": 3,
"name": null,
"dateOfBirth": null,
"weight": 0.0,
"breed": null,
"firstVaccination": null,
"secondVaccination": null,
"fileUpload": null,
"price": {
"id": 3,
"broadPrice": 8000.0,
"firstVaccinationPrice": 80.5,
"secondVaccinationPrice": 80.1,
"totalPrice": 8160.6
}
}
I've tried changing the code in several places, but I can't figure out why it outputs the price part and not the kitten data part. I want it to output the kitten data. So basically what I want is for him to reverse it, return data of the kittens and give data of the prices that are null.
My files look like this.

I have a lot to say about your code here, but let's see what's the main problem here. The problem is simple if you look at your KittenBuilder you create a Kitten using this builder but your Kitten constructor is empty.
public Kitten(String name, LocalDate dateOfBirth, double weight, String breed, String firstVaccination, String secondVaccination) {
this.name = name;
this.dateOfBirth = dateOfBirth;
this.weight = weight;
this.breed = breed;
this.firstVaccination = firstVaccination;
this.secondVaccination = secondVaccination;
}
This will populate the Kitten object and you're ready to go.
Some advices about your code
If you wonder why it's saving the null values when you specified the null constraints is that recent version of spring boot don't include the validation starter in the web starter, you have to include it yourself.
In you pom.xml add the following dependecy:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-validation</artifactId>
</dependency>
And you have to include the annotation #Transactional to your services to make your operations atomic, for example in your create kitten method you want to persist the price and the kitten atomically.
#Service
#Transactional
class KittenServiceImpl implementes ...
And one the best practices also, is to not use your entites directly in your controllers, use DTO (Data Transfer Object), so you map the properties you want from your entity to your DTO (this way you can include only your kitten properties and leave the price entity).
And last bonus:
public Kitten getKittenById(long id) {
if (!kittenRepository.existsById(id)) {
throw new RecordNotFoundException("");
}
return kittenRepository.findById(id).orElse(null);
}
This can be simplified to:
public Kitten getKittenById(long id) {
return kittenRepository.findById(id).orElseThrow(() -> new RecordNotFoundException());
}

But when trying to deserialise with this func

I get the following error:
com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_ARRAY but was BEGIN_OBJECT at line 1 column 2 path $
Any idea what might be the issue? This looks like a fairly simple json that the rest service returns, but I have not been able to get it work, any help would be greatly appreciated.

Right after I had written the question, I found out the answer, of course the top level class should not be a list, just the class it self. But I have a secondary question, can the three mapper classes be mounted into one class, just a cosmetic issue?

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();

Develop Reference

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

Consuming a third party RESTful API passing a parameter - java

You can always try to put the results from the third party API into a Map. Map results = restTemplate.postForObject(uri,brokerRequest, Map.class); Or you can create a new pojo just for that third part API. ThirdPartyPojo results = restTemplate.postForObject(uri,brokerRequest, ThirdPartyPojo.class);
