I'm trying to parse this structured of json string to Java Object but I failed every attempt.
{
"message": "Test Message",
"status": true,
"users": {
"user_xy": [
{
"time": "2016-08-25 19:01:20.944614158 +0300 EEST",
"age": 24,
"props": {
"pr1": 197,
"pr2": 0.75,
"pr3": 0.14,
"pr4": -0.97
}
}
],
"user_zt": [
{
"time": "2016-08-25 17:08:36.920891187 +0300 EEST",
"age": 29,
"props": {
"pr1": 1.2332131860505051,
"pr2": -0.6628148829634317,
"pr3": -0.11622442112006928
}
}
]
}
}
props field can contain 1 properties or 6 properties, it depends on db record. Also Username part dynamically changing.
Can I parse successfully this structured string with Jackson Lib?
You have to create calss structure like bellow to map your string to java object.
Create one class for Details
public class Details {
private String message;
private String status;
private Map<String, List<UserDetails>> users = new HashMap<String, List<UserDetails>>();
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public String getStatus() {
return status;
}
public void setStatus(String status) {
this.status = status;
}
public Map<String, List<UserDetails>> getUsers() {
return users;
}
public void setUsers(Map<String, List<UserDetails>> users) {
this.users = users;
}
}
Create UserDetails class like bellow.
public class UserDetails {
private String time;
private String age;
private Map<String, String> prop = new HashMap<String, String>();
public String getTime() {
return time;
}
public void setTime(String time) {
this.time = time;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
public Map<String, String> getProp() {
return prop;
}
public void setProp(Map<String, String> prop) {
this.prop = prop;
}
}
Now you can map your string with Details class.
Hope this will help..
public class Details {
private String message;
private boolean status;
Users UsersObject;
// Getter Methods
public String getMessage() {
return message;
}
public boolean getStatus() {
return status;
}
public Users getUsers() {
return UsersObject;
}
// Setter Methods
public void setMessage(String message) {
this.message = message;
}
public void setStatus(boolean status) {
this.status = status;
}
public void setUsers(Users usersObject) {
this.UsersObject = usersObject;
}
}
public class Users {
ArrayList < Object > user_xy = new ArrayList < Object > ();
ArrayList < Object > user_zt = new ArrayList < Object > ();
// Getter Methods
// Setter Methods
}
You can also use online JSON to JAVA Object Converter : https://codebeautify.org/json-to-java-converter

I'm new to mongodb and struggle a bit. I want to store a class which contains a HashMap which contains other objects. When I store the object it works without any error and the document in the database looks good. But retrieving the document results in an error:
Caused by: java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType
My (simplified) classes look like this:

I created morphia and told it how to map:
morphia = new Morphia();
morphia.map(AbbyyParameters.class,
CustomProfile.class,
ProfileProperties.class,
ProfileProperty.class);
After storing the class in the database the document look like this:
{
"_id" : ObjectId("5b2906a0cac45b8d42bbda91"),
"wordListEncoding" : "ISO-8859-15",
"description" : "",
"name" : "1",
"predefinedProfile" : {
"type" : "DEFAULT"
},
"customProfile" : {
"properties" : {
"PageAnalysisParams" : {
"properties" : [
{
"name" : "DetectBarcodes",
"value" : "true"
}
]
},
"RecognizerParams" : {
"properties" : [
{
"name" : "TextLanguage",
"value" : "English,German,Digits,French,Italian,Spanish,Croatian,Slovak,Bulgarian"
}
]
}
}
},
"treatBarcodeAsWord" : false,
"documentExportEnabled" : false,
"creationDate" : ISODate("2018-06-19T13:35:26.019Z"),
"changedDate" : ISODate("2018-06-19T13:35:28.441Z")
}
When I try to retrieve the document I get the following error:
Caused by: java.lang.ClassCastException: java.lang.Class cannot be cast to java.lang.reflect.ParameterizedType
at org.mongodb.morphia.mapping.EmbeddedMapper.readMap(EmbeddedMapper.java:166)
I stepped into the code so I found that this code raises the exception:
new EphemeralMappedField((ParameterizedType) mf.getSubType(), mf, mapper);
mf.getSubType() returns ProfileProperties so I guess I have misconfigured something there?
What do I have to do that I can retrieve my document?
I starting out with RxJava and Retrofit and wanted to create a simple app to show a list of 100 cryptocurrencies.
I am making an api call which results in something like this :
{
"Response": "Success",
"Message": "Coin list succesfully returned!",
"BaseImageUrl": "https://www.cryptocompare.com",
"BaseLinkUrl": "https://www.cryptocompare.com",
"Data": {
"LTC": {
"Id": "3808",
"Url": "/coins/ltc/overview",
"ImageUrl": "/media/19782/ltc.png",
"Name": "LTC",
"CoinName": "Litecoin",
"FullName": "Litecoin (LTC)",
"Algorithm": "Scrypt",
"ProofType": "PoW",
"SortOrder": "2"
}
...
},
"Type": 100
}
But all I want from this is "Response" and "Data". Since it is not practical to create a 100 different model classes for each coin, I want to store information of all the coins in a common class named Coin which would look something like this :
public class Coins {
#SerializedName("Algorithm")
private String mAlgorithm;
#SerializedName("CoinName")
private String mCoinName;
#SerializedName("FullName")
private String mFullName;
#SerializedName("FullyPremined")
private String mFullyPremined;
#SerializedName("Id")
private String mId;
#SerializedName("ImageUrl")
private String mImageUrl;
#SerializedName("Name")
private String mName;
#SerializedName("PreMinedValue")
private String mPreMinedValue;
#SerializedName("ProofType")
private String mProofType;
#SerializedName("SortOrder")
private String mSortOrder;
#SerializedName("Sponsored")
private Boolean mSponsored;
#SerializedName("Symbol")
private String mSymbol;
#SerializedName("TotalCoinSupply")
private String mTotalCoinSupply;
#SerializedName("TotalCoinsFreeFloat")
private String mTotalCoinsFreeFloat;
#SerializedName("Url")
private String mUrl;
public String getAlgorithm() {
return mAlgorithm;
}
public void setAlgorithm(String Algorithm) {
mAlgorithm = Algorithm;
}
public String getCoinName() {
return mCoinName;
}
public void setCoinName(String CoinName) {
mCoinName = CoinName;
}
public String getFullName() {
return mFullName;
}
public void setFullName(String FullName) {
mFullName = FullName;
}
public String getFullyPremined() {
return mFullyPremined;
}
public void setFullyPremined(String FullyPremined) {
mFullyPremined = FullyPremined;
}
public String getId() {
return mId;
}
public void setId(String Id) {
mId = Id;
}
public String getImageUrl() {
return mImageUrl;
}
public void setImageUrl(String ImageUrl) {
mImageUrl = ImageUrl;
}
public String getName() {
return mName;
}
public void setName(String Name) {
mName = Name;
}
public String getPreMinedValue() {
return mPreMinedValue;
}
public void setPreMinedValue(String PreMinedValue) {
mPreMinedValue = PreMinedValue;
}
public String getProofType() {
return mProofType;
}
public void setProofType(String ProofType) {
mProofType = ProofType;
}
public String getSortOrder() {
return mSortOrder;
}
public void setSortOrder(String SortOrder) {
mSortOrder = SortOrder;
}
public Boolean getSponsored() {
return mSponsored;
}
public void setSponsored(Boolean Sponsored) {
mSponsored = Sponsored;
}
public String getSymbol() {
return mSymbol;
}
public void setSymbol(String Symbol) {
mSymbol = Symbol;
}
public String getTotalCoinSupply() {
return mTotalCoinSupply;
}
public void setTotalCoinSupply(String TotalCoinSupply) {
mTotalCoinSupply = TotalCoinSupply;
}
public String getTotalCoinsFreeFloat() {
return mTotalCoinsFreeFloat;
}
public void setTotalCoinsFreeFloat(String TotalCoinsFreeFloat) {
mTotalCoinsFreeFloat = TotalCoinsFreeFloat;
}
public String getUrl() {
return mUrl;
}
public void setUrl(String Url) {
mUrl = Url;
}
}
So finally my mapped response class would look like :
public class CoinsListResponse {
private boolean success;
private List<Coins> coinsList;
public boolean isSuccess() {
return success;
}
public void setSuccess(boolean success) {
this.success = success;
}
public List<Coins> getCoinsList() {
return coinsList;
}
public void setCoinsList(List<Coins> coinsList) {
this.coinsList = coinsList;
}
}
I haven't added #Serialized notations because I don't know what key to annotate it with.
My Retrofit service interface has a method to return the results to this map :
public interface CoinService {
#NonNull
#POST
Observable<CoinsListResponse> getCoinList();
}
Since, I am a starter with Retrofit and RxAndroid, there might be a better method to do this, which I am not aware of. If so, please mention that as well !! I am trying to get my head around this for days but couldn't find any answer on SO as well.
Please Help !!
Change
private List<Coins> coinsList;
to
#SerializedName("Data")
private Map<String, Coins> coinsByName;
You can then either just use coinsByName.values() or call e.g. coinsByName.get("LTC")
I'm trying to read the values from a JSON URL, however I don't know how I can proceed with reading the values from a List inside of an Array? Below you will find my POJO, Main, and JSON code. Thank you so much for your help
POJO:
package org.jcexchange.FBApp;
import java.util.List;
import org.jcexchange.FBApp.Details;
public class Users {
private List<Details> Values;
public List<Details> getValues() {
return this.Values;
}
public void setValues(List<Details> Values) {
this.Values = Values;
}
}
public class Details {
private String user_name;
private String user_password;
private int age;
private String user_email;
public String getUserName() {
return this.user_name;
}
public void setUserName(String user_name) {
this.user_name = user_name;
}
public String getUserPassword() {
return this.user_password;
}
public void setUserPassword(String user_password) {
this.user_password = user_password;
}
public int getAge() {
return this.age;
}
public void setAge(int age) {
this.age = age;
}
public String getUserEmail() {
return this.user_email;
}
public void setUserEmail(String user_email) {
this.user_email = user_email;
}
}
Main:
public class Main {
public static void main(String[] args) {
try {
URL jsonURL = new URL("https://jchtest.herokuapp.com/index.php?
PW=2");
ObjectMapper mapper = new ObjectMapper();
mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES,
false);
Users[] a1 = mapper.readValue(jsonURL, Users[].class);
}
catch (Exception e) {
throw new RuntimeException(e);
}
}
}
I'm able to pull the JSON from a webservice, however I'm stuck trying to figure out how I could retrieve for instance the user_name from the first "Values" index of the JSON array
JSON:
[
{
"Values": {
"user_name": "jhart",
"user_password": "gooddeval1",
"age": 28,
"user_email": "heheh"
}
},
{
"Values": {
"user_name": "bdole",
"user_password": "Passwordd",
"age": 82,
"user_email": "hahah"
}
}
]
Well , it is a little confusing here may be because i dont have the full context. From the de-serializer you are telling me that i expect an Array of Users and then within each User i have a List of "Values" , but the JSON tells me that Values is a singular property for Users. Anyways , here is a sample that works on the assumption i have made. This can be fiddled around to change the collection and singular properties
import org.codehaus.jackson.annotate.JsonProperty;
public class Users {
#JsonProperty("Values")
private Details Values;
public Details getValues() {
return this.Values;
}
public void setValues(Details Values) {
this.Values = Values;
}
}
import org.codehaus.jackson.annotate.JsonProperty;
public class Details {
#JsonProperty("user_name")
private String user_name;
#JsonProperty("user_password")
private String user_password;
#JsonProperty("age")
private int age;
#JsonProperty("user_email")
private String user_email;
public String getUserName() {
return this.user_name;
}
public void setUserName(String user_name) {
this.user_name = user_name;
}
public String getUserPassword() {
return this.user_password;
}
public void setUserPassword(String user_password) {
this.user_password = user_password;
}
public int getAge() {
return this.age;
}
public void setAge(int age) {
this.age = age;
}
public String getUserEmail() {
return this.user_email;
}
public void setUserEmail(String user_email) {
this.user_email = user_email;
}
}
import java.net.URL;
import org.codehaus.jackson.map.ObjectMapper;
public class Main {
public static void main(String[] args) {
try {
URL jsonURL = new URL("https://jchtest.herokuapp.com/index.php?PW=2");
ObjectMapper mapper = new ObjectMapper();
Users[] a1 = mapper.readValue(jsonURL, Users[].class);
System.out.println(a1[0].getValues().getUserName());
} catch (Exception e) {
throw new RuntimeException(e);
}
}
}
This prints "jhart" for me.
Please note : One thing you can try is based on the array/singular property you can populate the Object and write it as JSON. That way you can find what is different in what Jackson Deserializer expects vs What we are actually supplying.

Can you try the following and see whether helps:
ResponseEntity<Events[]> responseEntity = restTemplate
.getForEntity(
"http://primesport.sieenasoftware.com/QryApi
/GetEvents?
username=username&
password=password&
userid=23",
Events[].class);
System.err.println(">>" + responseEntity.getBody().length);
For mapping the fields to the JSON members you can use Jackson annotation JSONProperty("EventId") can be used for the eventId field. Similarly for others.
#JsonProperty("EventId")
private long eventId;
#JsonProperty("Name")
private String name;
Have you tried to see the exact request getting generated? Let's say in a proxy software like fiddler/charles?
Sometimes I have experienced, the framework adds additional constructs(encoding, etc), before the requests actually really gets to the wire(or reaching the server endpoint).
Try this, to create the request. Even the documentation for RestTemplate suggests to avoid double encoding for URL. It may not be very apparent when looking in the IDE.
String url = "http://primesport.sieenasoftware.com/QryApi/GetEvents?";
MultiValueMap<String, String> params = new LinkedMultiValueMap<String, String>();
params.add("username", "username");
params.add("password", "password");
params.add("userid", "23");
UriComponents uriComponents = UriComponentsBuilder.fromHttpUrl(url).queryParams(params).build();
System.out.println(uriComponents.toUri());
Please let me know, how it works out.
Also, please let know, if you cant find steps to setup fiddler proxy. It quite a handy tool, while coding the service clients.
According to the json format, all you need is using the Event class instead of the Result class.
Or change the JSON result to this :
["events": {
"EventId":1000250537,
"Name":"US Open Golf",
"SubTitle":null,
"Description":"US Open Golf Tickets",
"Date":"\/Date(1434873560000)\/",
"LocalDate":"6/20/2015 11:59 PM",
"LocalDateFrom":null,
"ImageUrl":null,
"VenueId":146566,
"Venue":"Chambers Bay Golf Course",
"AvailableTickets":33,
"PerformerId":151551,
"Performer":"US Open Golf",
"PerformerType":"Golf",
"SubcategoryId":55,
"UrlCategoryName":"Sports",

You can try importing Jackson Jar or add dependency in pom.xml if you are using Maven.
ObjectMapper mapper = new ObjectMapper();
try
{
mapper.writeValue(new File("c://temp/employee.json"), Results);
}
I have tried several ways to create follwing format json using java. (Gson , Jackson , ...)
{
"outbound": {
"address": [
"t91",
"t0992"
],
"send": "t678",
"outMessage": {
"message": "Hello World"
},
"client": "156",
"receipt": {
"URL": "http://example.com/Delivery",
"callback": "some-to-the-request"
},
"senderName": "Inc."
}
}
Any help?
Use code below.
Create POJO
public class TestPojo {
private Outbound outbound;
public Outbound getOutbound() {
return outbound;
}
public void setOutbound(Outbound outbound) {
this.outbound = outbound;
}
}
class Outbound {
private String[] address;
private String send;
private OutMessage outMessage;
private Receipt receipt;
private String senderName;
public String[] getAddress() {
return address;
}
public void setAddress(String[] address) {
this.address = address;
}
public String getSend() {
return send;
}
public void setSend(String send) {
this.send = send;
}
public OutMessage getOutMessage() {
return outMessage;
}
public void setOutMessage(OutMessage outMessage) {
this.outMessage = outMessage;
}
public Receipt getReceipt() {
return receipt;
}
public void setReceipt(Receipt receipt) {
this.receipt = receipt;
}
public String getSenderName() {
return senderName;
}
public void setSenderName(String senderName) {
this.senderName = senderName;
}
}
class OutMessage {
private String message;
public OutMessage(String message) {
super();
this.message = message;
}
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
}
class Receipt {
private String URL;
private String callback;
public Receipt(String uRL, String callback) {
super();
URL = uRL;
this.callback = callback;
}
public String getURL() {
return URL;
}
public void setURL(String uRL) {
URL = uRL;
}
public String getCallback() {
return callback;
}
public void setCallback(String callback) {
this.callback = callback;
}
}
Main Class (JSON to Object)
String json = "{'outbound':{'address':['t91','t0992'],'send':'t678','outMessage':{'message':'Hello World'},'receipt':{'URL':'http://example.com/Delivery','callback':'some-to-the-request'},'senderName':'Inc.'}}";
TestPojo testPojo = new Gson().fromJson(json, TestPojo.class);
System.out.println(testPojo.getOutbound().getSenderName());
Output
Inc.
Main Class (Object to JSON)
TestPojo testPojo = new TestPojo();
Outbound outbound = new Outbound();
outbound.setAddress(new String[]{"t91", "t0992"});
outbound.setOutMessage(new OutMessage("Hello World"));
outbound.setReceipt(new Receipt("http://example.com/Delivery", "some-to-the-request"));
outbound.setSenderName("Inc.");
outbound.setSend("t678");
testPojo.setOutbound(outbound);
System.out.println(new Gson().toJson(testPojo));
Output
{"outbound":{"address":["t91","t0992"],"send":"t678","outMessage":{"message":"Hello World"},"receipt":{"URL":"http://example.com/Delivery","callback":"some-to-the-request"},"senderName":"Inc."}}
