Post HashMap as a POST request Value in Android Retrofit Post call - java

Here I want to send a hashMap as a Post request data.
In my Post request I have to send Data like
{
"dd98e151-3a57-45f5-b201-e7f5250bce8b": {
"ratingid": "64d2fa13-bf17-4242-9106-c1a722cd1063",
"compid": "dd98e151-3a57-45f5-b201-e7f5250bce8b",
"avgrat": "4.00",
"continue": " ",
"improve": " ",
"ratingindicators": [
{
"internalname": "c1",
"name": "CI 1",
"rating": "4"
},
{
"internalname": "CI 3",
"name": "CI 3 only ",
"feedback": "text"
},
{
"internalname": "I2",
"name": "CI 2",
"rating": "0"
}
]
},
"e6c6d37c-a9e6-491f-9f76-8375cee2096f": {
"ratingid": "64d2fa13-bf17-4242-9106-c1a722cd1063",
"compid": "dd98e151-3a57-45f5-b201-e7f5250bce8b",
"avgrat": "4.00",
"continue": " ",
"improve": " ",
"ratingindicators": [
{
"internalname": "c1",
"name": "CI 1",
"rating": "4"
},
{
"internalname": "CI 3",
"name": "CI 3 only ",
"feedback": "text"
},
{
"internalname": "I2",
"name": "CI 2",
"rating": "0"
}
]
}
}
To post that data in API call I have created a HashMap like
Map<String,PostIndicatorsModel>> map=new HashMap<String,PostIndicatorsModel>();
And Here PostIndicatorsModel is an pojo/model class
PostIndicatorsModel.java
public class FeeddbackPostIndicatorsModel {
#SerializedName("ratingid")
#Expose
private String feedbackratingid;
#SerializedName("compid")
#Expose
private String competencyid;
#SerializedName("avgrat")
#Expose
private String avgrating;
#SerializedName("continue")
#Expose
private String whattocontinue = "";
#SerializedName("improve")
#Expose
private String whattoimprove = "";
#SerializedName("ratingindicators")
#Expose
private List<Ratingindicator> ratingindicators = null;
public String getRatingid() {
return ratingid;
}
public void setRatingid(String ratingid) {
this.ratingid = ratingid;
}
public String getCompid() {
return compid;
}
public void setCompid(String compid) {
this.compid = compid;
}
public String getAvgrat() {
return avgrat;
}
public void setAvgrat(String avgrat) {
this.avgrat = avgrat;
}
public String getContinue() {
return _continue;
}
public void setContinue(String _continue) {
this._continue = _continue;
}
public String getImprove() {
return improve;
}
public void setImprove(String improve) {
this.improve = improve;
}
public List<Ratingindicator> getRatingindicators() {
return ratingindicators;
}
public void setRatingindicators(List<Ratingindicator> ratingindicators) {
this.ratingindicators = ratingindicators;
}
public static class Ratingindicator{
#SerializedName("internalname")
#Expose
private String internalname;
#SerializedName("name")
#Expose
private String name;
#SerializedName("rating")
#Expose
private String rating;
#SerializedName("feedback")
#Expose
private String feedback;
public String getInternalname() {
return internalname;
}
public void setInternalname(String internalname) {
this.internalname = internalname;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getRating() {
return rating;
}
public void setRating(String rating) {
this.rating = rating;
}
public String getFeedback() {
return feedback;
}
public void setFeedback(String feedback) {
this.feedback = feedback;
}
}
}
Please help me to understand how to call post API with this HashMap
Map<String,PostIndicatorsModel>> map=new HashMap<String,PostIndicatorsModel>();
In API call
#FormUrlEncoded
#POST(SURL.POST_INDICATORS)
Call<PostIndicatorsModel> postRate360(#Path("rateId") String rateId, #Body Map<String,PostIndicatorsModel> post);
I tried with #Body, #FeildMap,#QueryMap but it shows an error in call or server not getting data from post-call as required.
Please help me to understand how can i do this

Getting Json object and Json Array in Same KEY

I am getting JSON Object when their is only one response(Plan) and JSON Array when their is more than one response(plan).How to handle JSON Response?
JSON ARRAY when their is more than one plan.
{
"ocrNumber": "0123456",
"userName": "dddd",
"plan": [{
"lat": "13.1234",
"long": "7.1234",
"imagepath": "sd / image / demo.jpg"
},{
"lat": "13.1234",
"long": "7.1234",
"imagepath": "sd / image / demo.jpg"
}]
}
JSON OBJECT when their is only one plan.
{
"ocrNumber": "0123456",
"userName": "dddd",
"plan": {
"lat": "13.1234",
"long": "7.1234",
"imagepath": "sd / image / demo.jpg"
}
}

add dependencies in your app level gradle file.
implementation 'com.google.code.gson:gson:2.8.5'
Create MyResponse.java
public class MyResponse {
#SerializedName("ocrNumber")
private String ocrNumber;
#SerializedName("userName")
private String userName;
#SerializedName("plan")
private ArrayList<Plan> plan;
public String getOcrNumber() {
return ocrNumber;
}
public void setOcrNumber(String ocrNumber) {
this.ocrNumber = ocrNumber;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public ArrayList<Plan> getPlan() {
return plan;
}
public void setPlan(ArrayList<Plan> plan) {
this.plan = plan;
}
}
create Plan.java class
public class Plan {
#SerializedName("lat")
private String lat;
#SerializedName("long")
private String longStr;
#SerializedName("imagepath")
private String imagepath;
public String getLat() {
return lat;
}
public void setLat(String lat) {
this.lat = lat;
}
public String getLongStr() {
return longStr;
}
public void setLongStr(String longStr) {
this.longStr = longStr;
}
public String getImagepath() {
return imagepath;
}
public void setImagepath(String imagepath) {
this.imagepath = imagepath;
}
}
Convert your jsonString to object using Gson
Gson gson = new Gson();
MyResponse response = gson.fromJson(yourJsonString, MyResponse.class);

Parsing JSON in Java returns empty result

I am trying to parse a JSON with Java and I do not get the expected result.
Example json:
"productId": "NDAtOS0wLS0=",
"branchId": 5,
"branchCustomers":[
{"branchId":615,"customerNumber":4918,"products":[]},
{"branchId":615,"customerNumber":9753,"products":[]},

],
"customerNumber": 240,
"subAccountNumber": 0,
"productType": 9,
"openingDate": "2016-10-02",
"values": [
{
"key": "accountingMethod",
"value": "1"

]
}

}],
"instances": []
}
Not all the JSONs have this structure, some may miss some of the fields. I created some DTO classes for parsing it. This is my code:
public class Response {
private String partnerId;
private byte branchId;
private long customerNumber;
private Long subAccountNumber;
private Byte productType;
private String openingDate;
private String closingDate;
private List<Values> values;
private List<Instances> instances;
private List<BranchCustomers> branchCustomers;
public String getProductid() {
return partnerId;
}
public void setProductid(String productid) {
this.partnerId = productid;
}
public byte getBranchid() {
return branchId;
}
public void setBranchid(byte branchid) {
this.branchId = branchid;
}
public long getCustomernumber() {
return customerNumber;
}
public void setCustomernumber(long customernumber) {
this.customerNumber = customernumber;
}
public Long getSubaccountnumber() {
return subAccountNumber;
}
public void setSubaccountnumber(Long subAccountNumber) {
this.subAccountNumber = subAccountNumber;
}
public Byte getProducttype() {
return productType;
}
public void setProducttype(Byte productType) {
this.productType = productType;
}
public String getOpeningdate() {
return openingDate;
}
public void setOpeningdate(String openingDate) {
this.openingDate = openingDate;
}
public String getClosingdate() {
return closingDate;
}
public void setClosingdate(String closingDate) {
this.closingDate = closingDate;
}
public List<Values> getValues() {
return values;
}
public void setValues(List<Values> values) {
this.values = values;
}
public List<Instances> getInstances() {
return instances;
}
public void setInstances(List<Instances> instances) {
this.instances = instances;
}
public List<BranchCustomers> getBranchCustomers() {
return branchCustomers;
}
public void setBranchCustomers(List<BranchCustomers> branchCustomers) {
this.branchCustomers = branchCustomers;
}
}
public class BranchCustomers {
private byte branchId;
private long customerNumber;
private List<Products> products;
public byte getBranchid() {
return branchId;
}
public void setBranchid(byte branchId) {
this.branchId = branchId;
}
public long getCustomernumber() {
return customerNumber;
}
public void setCustomernumber(long customerNumber) {
this.customerNumber = customerNumber;
}
public List<Products> getProducts() {
return products;
}
public void setProducts(List<Products> products) {
this.products = products;
}
}
public void parseJson(String response) {
try{
ObjectMapper mapper = new ObjectMapper();
mapper.registerModule(new JavaTimeModule());
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
Response result = mapper.readValue(response, Response.class);
System.out.println(result);
} catch (JsonMappingException e) {
e.printStackTrace
} catch (JsonProcessingException e) {
e.printStackTrace();
}
The other DTO classes "Values", "Instances" and "Products" are empty at this moment, but I do not need them yet. The problem is that the "result" value has the right structure and the right fields, but they are null or 0, depending on their data type and I cannot see what I have done wrong.
Can anyone help me?

Your getters, setters have incorrect names.
As an example, in your Response object, you have getProductid, getBranchid, and getCustomernumber with similar setter methods. Your JSON however has productId, branchId, and customerNumber. They differ as you didn't use the correct capitalization. You should use camelCase, which would turn your naming to getProductId, getBranchId, and getCustomerNumber. This then matches the JSON and it will map accordingly.
This:
public class Response {
private String partnerId;
private byte branchId;
private long customerNumber;
private Long subAccountNumber;
private Byte productType;
private String openingDate;
private String closingDate;
private List<BranchCustomers> branchCustomers;
public String getProductId() {
return partnerId;
}
public void setProductId(String productid) {
this.partnerId = productid;
}
public byte getBranchId() {
return branchId;
}
public void setBranchId(byte branchid) {
this.branchId = branchid;
}
public long getCustomerNumber() {
return customerNumber;
}
public void setCustomerNumber(long customernumber) {
this.customerNumber = customernumber;
}
...
Leads to:
Response{productId='NDAtOS0wLS0=', branchId=5, customerNumber=240 ...
As a sidenote, I suggest either auto-generating the boilerplate code with your IDE or look into Project Lombok which can generate the boilerplate code by just adding an annotation. This also stops you from making naming mistakes.
Also, try and get a toString method for each pojo, as it will help you during logging or debugging.

Incorrectly processing RestTemplate response into object

I'm having some difficulty in parsing a response from a RestTemplate into an instance of a class I've defined.
When I come to process the results, it does give me the correct number of items in the array, but they are all set to default values - it seems unable to process the actual contents from each entry in the response.
This is my class:
public class Authority {
private long localAuthorityId;
private String localAuthorityIdCode;
private String name;
private String friendlyName;
private String url;
private String schemeUrl;
private String email;
private String regionName;
private String fileName;
private String fileNameWelsh;
private int establishmentCount;
private String creationDate;
private String lastPublishedDate;
private int schemeType;
private Link[] links;
public Authority() {}
public Authority (long localAuthorityId, String localAuthorityIdCode, String name, String friendlyName, String url, String schemeUrl,
String email, String regionName, String fileName, String fileNameWelsh, int establishmentCount, String creationDate,
String lastPublishedDate, int schemeType, Link[] links) {
this.localAuthorityId = localAuthorityId;
this.localAuthorityIdCode = localAuthorityIdCode;
this.name = name;
this.friendlyName = friendlyName;
this.url = url;
this.schemeUrl = schemeUrl;
this.email = email;
this.regionName = regionName;
this.fileName = fileName;
this.fileNameWelsh = fileNameWelsh;
this.establishmentCount = establishmentCount;
this.creationDate = creationDate;
this.lastPublishedDate = lastPublishedDate;
this.schemeType = schemeType;
this.links = links;
}
public long getLocalAuthorityId() {
return this.localAuthorityId;
}
public String getLocalAuthorityIdCode() {
return this.localAuthorityIdCode;
}
public String getName() {
return this.name;
}
public String getFriendlyName() {
return this.friendlyName;
}
public String getUrl() {
return this.url;
}
public String getSchemeUrl() {
return this.schemeUrl;
}
public String getEmail() {
return this.email;
}
public String getRegionName() {
return this.regionName;
}
public String getFilename() {
return this.fileName;
}
public String getFileNameWelsh() {
return this.fileNameWelsh;
}
public int getEstablishmentCount() {
return this.establishmentCount;
}
public String getCreationDate() {
return this.creationDate;
}
public String getLastPublishedDate() {
return this.lastPublishedDate;
}
public int getSchemeType() {
return this.schemeType;
}
public Link[] getLinks() {
return this.links;
}
}
This is my response wrapper (where I've confirmed it only ever calls the empty constructor):
public class MyResponseWrapper {
private Authority[] authorities;
public MyResponseWrapper() {
// this is always being called
}
public MyResponseWrapper(Authority[] authorities) {
this.authorities = authorities;
}
public Authority[] getAuthorities() {
return this.authorities;
}
}
And this is how I'm using the RestTemplate:
RestTemplate restTemplate = new RestTemplate();
HttpHeaders headers = new HttpHeaders();
headers.set("Accept", "application/json");
HttpEntity<String> entity = new HttpEntity<>("parameters", headers);
ResponseEntity<MyResponseWrapper> res = restTemplate.exchange(url, HttpMethod.GET, entity, MyResponseWrapper.class);
Here is the JSON I am attempting to parse (I only need the id and name parameters to be stored in MyClass):

I know I'm making a really basic mistake in attempting to parse this response. Would really appreciate if someone could point it out. Cheers.

Parse Json array with multiple objects using retrofit 2 in android

I'm using retrofit 2 for networking functions in my project, and I'm able to parse the json object responses from the server but now I'm supposed to parse a json array that look like this
[

Is my pojo is right ?
My problem is, I can't parse this response. Any help will be appreciated.
Thanks in advance
EDIT :
This is my request to server (using rest api)
#GET("url")
Call<AssetResponse> getAssetList();
EDIT 2: I've changed the code to List, as suggested by Niko Adrianus Yuwono.
This is the new changes
private void getAssets() {
HttpLoggingInterceptor logging = new HttpLoggingInterceptor();
logging.setLevel(HttpLoggingInterceptor.Level.BODY);
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(logging);
Retrofit retrofit = new Retrofit.Builder()
.baseUrl(Constants.BASE_URL)
.addConverterFactory(GsonConverterFactory.create())
.client(httpClient.build())
.build();
final ApiInterface apiInterface = retrofit.create(ApiInterface.class);
final AssetRequest assetRequest = new AssetRequest();
assetRequest.setAcc_tok(ACCESS_TOKEN);
final Call<List<AssetResponse>> assetList = apiInterface.getAssetList();
assetList.enqueue(new Callback <List<AssetResponse>>() {
#Override
public void onResponse(Call<List<AssetResponse>> call, Response<List<AssetResponse>> response) {
int statusCode = response.code();
List<AssetResponse> assetResponseList = response.body();
if (statusCode == 200) {
for (int i = 0; i < assetResponseList.size(); i++ ){
Integer id_asset = assetResponseList.get(i).getId_asset();
Integer id_category = assetResponseList.get(i).getId_category();
Integer status = assetResponseList.get(i).getStatus();
String name = assetResponseList.get(i).getName();
Log.d("Assets ","Asset id_asset bb : " + id_asset);
Log.d("Assets ","Asset id_category bb : " + id_category);
Log.d("Assets ","Asset name bb : " + name);
Log.d("Assets ","Asset status bb : " + status);
Double val = assetResponseList.get(i).getAssetRate().getValue();
Log.d("val ","val is : " +val);
}
} else {
Toast.makeText(getContext(), "network error " + statusCode, Toast.LENGTH_LONG).show();
}
}
#Override
public void onFailure(Call<List<AssetResponse>> call, Throwable t) {
Log.d("Asset GET Failure", "onFailure: " + t.getMessage());
//showProgress(false);

}
and this is the response from the server

Whenever I access the inner objects it throws error like the above

Your POJO looks right, but your JSON response is a JSONArray so you need to declare it as a List of Objects rather than an Object
#GET("url")
Call<List<AssetResponse>> getAssetList();
And you need to change your inner class access to public so GSON can see the setter and getter of that class.

Your Json key value data is changing from one index to another.
Wrong Json:
[{
//Make this either integer or boolean
"rank": 1,
// best rate is object here in the next index, it's treated as boolean.
"best_rate": {
"id_asset": "1",
"value": "5000",
"loan_to_value": "50",
"offered": "2500",
"annual_rate": "3",
"quantity": "5",
"rank": "1"
}
},
{
"rank":false,
"best_rate":false,
}
]
I have a complete project shared on github with your json.
https://github.com/lingarajsankaravelu/retrofit2v.git
Retrofit code should be like this as i mentioned in the question comment.
#GET("url")
Call<List<AssetResponse>> getAssetList();
As you have requested to explain the changes in your pojo class it should be like this.

Seperate your inner class like above. Seperating your inner class model will be useful if you are working on a large project. where you don't have to write the same pojo class again. you can use this seperate class structure instead.

You can use this site to generate POJO class. Just enter your JSON response and choose which JSON type you using like GSON,Jackson.etc. and You get perfect POJO classes. no need to change anything.
http://www.jsonschema2pojo.org/

Your Retrofit interface should be
#GET("url")
Call<List<AssetReponse>> getAssessList();
And make sure that your variable name same with key on JSON Response Or you can use annotation #SerializedName for that & for make it simple you can use JSON to POJO Online converter : http://www.jsonschema2pojo.org/

Rest Assured - Post nested POJO in Body

I'm trying to write an API class to send requests and handle responses from an API. Parts of the API have requests that require JSON bodies attached to the request such as this sample:
{
"Title": "string",
"Status": "string",
"ActFinish": "Date",
"ActHrs": "float",
"ActStart": "Date",
"ActualResults": "string",
"AssigneeUserId": "int",
"CustomFields": [
{
"Id": "string",
"Name": "string",
"Value": "string"
}
],
"Description": "string",
"EstFinish": "Date",
"EstHrs": "float",
"EstHrsRemaining": "float",
"EstStart": "Date",
"ExpectedResults": "string",
"FolderId": "int",
"FunctionalAreaCode": "string",
"HowFoundCode": "string",
"IssueCode": "string",
"ModuleCode": "string",
"PctComplete": "int",
"PriorityCode": "string",
"Resolution": "string",
"ResolutionCode": "string",
"SeverityCode": "string",
"SoftwareVersionCode": "string",
"StepsToRepro": "string"
}
The best way to do this I found through reading the Rest Assured documentation is with POJOs mentioned here: https://github.com/rest-assured/rest-assured/wiki/Usage#serialization
My POJO looks like this:
public class RequestDefectPost {
public String title;
public String status;
public Timestamp actFinish;
public float actHours;
public Timestamp actStart;
public String actualResults;
public int assigneeUserId;
public String[] customFields;
public String id;
public String name;
public String value;
public String description;
public Timestamp estFinish;
public float estHours;
public float estHrsRemaining;
public Timestamp estStart;
public String expectedResults;
public int folderId;
public String functionalAreaCode;
public String howFoundCode;
public String issueCode;
public String moduleCode;
public int pctComplete;
public String priorityCode;
public String resolutionCode;
public String severityCode;
public String softwareVersionCode;
public String stepsToRepro;
public RequestDefectPost(String title, String status) {
this.title = title;
this.status = status;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public Timestamp getActFinish() {
return actFinish;
}
public void setActFinish(Timestamp actFinish) {
this.actFinish = actFinish;
}
public float getActHours() {
return actHours;
}
public void setActHours(float actHours) {
this.actHours = actHours;
}
public Timestamp getActStart() {
return actStart;
}
public void setActStart(Timestamp actStart) {
this.actStart = actStart;
}
public String getActualResults() {
return actualResults;
}
public void setActualResults(String actualResults) {
this.actualResults = actualResults;
}
public int getAssigneeUserId() {
return assigneeUserId;
}
public void setAssigneeUserId(int assigneeUserId) {
this.assigneeUserId = assigneeUserId;
}
public String[] getCustomFields() {
return customFields;
}
public void setCustomFields(String id, String name, String value) {
this.customFields = new String[]{this.id = id, this.name = name, this.value = value};
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public Timestamp getEstFinish() {
return estFinish;
}
public void setEstFinish(Timestamp estFinish) {
this.estFinish = estFinish;
}
public float getEstHours() {
return estHours;
}
public void setEstHours(float estHours) {
this.estHours = estHours;
}
public float getEstHrsRemaining() {
return estHrsRemaining;
}
public void setEstHrsRemaining(float estHrsRemaining) {
this.estHrsRemaining = estHrsRemaining;
}
public Timestamp getEstStart() {
return estStart;
}
public void setEstStart(Timestamp estStart) {
this.estStart = estStart;
}
public String getExpectedResults() {
return expectedResults;
}
public void setExpectedResults(String expectedResults) {
this.expectedResults = expectedResults;
}
public int getFolderId() {
return folderId;
}
public void setFolderId(int folderId) {
this.folderId = folderId;
}
public String getFunctionalAreaCode() {
return functionalAreaCode;
}
public void setFunctionalAreaCode(String functionalAreaCode) {
this.functionalAreaCode = functionalAreaCode;
}
public String getHowFoundCode() {
return howFoundCode;
}
public void setHowFoundCode(String howFoundCode) {
this.howFoundCode = howFoundCode;
}
public String getIssueCode() {
return issueCode;
}
public void setIssueCode(String issueCode) {
this.issueCode = issueCode;
}
public String getModuleCode() {
return moduleCode;
}
public void setModuleCode(String moduleCode) {
this.moduleCode = moduleCode;
}
public int getPctComplete() {
return pctComplete;
}
public void setPctComplete(int pctComplete) {
this.pctComplete = pctComplete;
}
public String getPriorityCode() {
return priorityCode;
}
public void setPriorityCode(String priorityCode) {
this.priorityCode = priorityCode;
}
public String getResolutionCode() {
return resolutionCode;
}
public void setResolutionCode(String resolutionCode) {
this.resolutionCode = resolutionCode;
}
public String getSeverityCode() {
return severityCode;
}
public void setSeverityCode(String severityCode) {
this.severityCode = severityCode;
}
public String getSoftwareVersionCode() {
return softwareVersionCode;
}
public void setSoftwareVersionCode(String softwareVersionCode) {
this.softwareVersionCode = softwareVersionCode;
}
public String getStepsToRepro() {
return stepsToRepro;
}
public void setStepsToRepro(String stepsToRepro) {
this.stepsToRepro = stepsToRepro;
}
}
With my current POJO, the JSON being spit out by Rest Assured looks like this:
{
"title": "Test",
"status": "New",
"actFinish": null,
"actHours": 0.0,
"actStart": null,
"actualResults": null,
"assigneeUserId": 0,
"customFields": [
"Test",
"test",
"tesT"
],
"id": "Test",
"name": "test",
"value": "tesT",
"description": null,
"estFinish": null,
"estHours": 0.0,
"estHrsRemaining": 0.0,
"estStart": null,
"expectedResults": null,
"folderId": 0,
"functionalAreaCode": null,
"howFoundCode": null,
"issueCode": null,
"moduleCode": null,
"pctComplete": 0,
"priorityCode": null,
"resolutionCode": null,
"severityCode": null,
"softwareVersionCode": null,
"stepsToRepro": null
}
My question is how do I write the the customFields such that it is nested correctly, as outlined in the sample JSON?

You need another POJO that represents a "CustomFields". For example:
public class CustomFields {
private String Id;
private String Name;
private String Value;
<getters and setters>
}
and use List<CustomFields> CustomFields instead of String[] customFields. Also note that your JSON example doesn't use camel case for the property names so your POJO shouldn't use camel case either.
There are ways to avoid using a POJO at all in REST Assured. You can for example use a HashMap instead which could be easier in some situations.
