I just started with rest services and i have read this https://spring.io/guides/gs/consuming-rest/. Then according to this tutorial i have a service to consume and display.
The service is a rest api and i get a json like that
{
"disclaimer": "1",
"license": "2",
"timestamp": 1458057661,
"base": "someValue",
"rates": {
"one": 3.673019,
"two": 68.449999,
"three": 124.168,
"four": 488.669996,
...,
...,
...
}
}
Then i have created 2 Java class like that
#JsonIgnoreProperties(ignoreUnknown = true)
public class Cur {
private String disclaimer;
private String license;
private String timestamp;
private String base;
private Rates rates;
public Cur() {
super();
}
///get/set
///tostring
}
#JsonIgnoreProperties(ignoreUnknown = true)
public class Rates {
public Rates(){
//// i am not sure here how should i get the rates value.
}
}
the problem is how do i fill the Rates class to get the data into variables so that later i can present the on view.
I use RestTemplate. Here is the test.It works but i have no rates value.
I think i need a Map because rates it's a collection.Any idea how to implement it.
#Test
public void getCurTest() {
String URL="some url";
String JSONTYPE="some json type";
String API="some id";
RestTemplate restTemplate = new RestTemplate();
Cur cur= restTemplate.getForObject(URL+JSONTYPE+API, Cur.class);
log.info("cur");
System.out.println(cur);
}
I had the same some years ago it's a little weird. Here what you can do.
First solution
The simple way is
CloseableHttpClient httpclient = HttpClients.createDefault();
HttpGet httpget = new HttpGet("your rest service api");
CloseableHttpResponse response = httpclient.execute(httpget);
try {
HttpEntity entity = response.getEntity();
if (HttpStatus.SC_OK == response.getStatusLine().getStatusCode()) {
String responseValue = EntityUtils.toString(entity);
System.out.println(responseValue);
} else {
// log error
}
} finally {
response.close();
}
}
you can then get everything as a String and with regex parse it and get what you want.
Second solution
you can save all your rest to a database as it is. Use mongodb for faster.
Then you can get it form there to a class and use it.
Third solution
use this tool http://www.jsonschema2pojo.org/ just paste your json and it will create your java classes to use them. You can choose what ever you want to add. This will create your classes then you can use them.
Here for your convenience.

I hope all this helps. Take care.
The way your JSON is, to get the Rates populed your class should look like this.
public class Cur {
private String disclaimer;
private String license;
private Integer timestamp;
private String base;
private Rates rates;
}
public class Rates {
private Double one;
private Double two;
private Double three;
private Double four;
//This would be better but the JSON dosnt fit this
//private Map<String, Double> rates;
}
Which API are you triyng to use?

i am trying to pass a custom object via retrofit2, and my question is that does the server writes my custom object to json automatically or do i have to write a php file for that. In the meanwhile I am posting successfully to the server but unable to write to json.
My aim is to write custom object to server, and write the contents of custom objects to json file.
Here is my Retrofit Api
public interface ApsaraCatalogAPI {
#GET("/apsaratrendz/data/apsara_json_document_v2.json")
Call<List<ApsaraCatalogModel>> getFeed();
#POST("/apsaratrendz/data/apsara_json_orders_document.json")
Call<Void> setOrder(#Body OrderModel orderModel);
}
Here is my calling api function
#Override
public void onClick(View v) {
int total = 0;
if(v.getId()==R.id.fabButtonCart && cartlist.size()!=0)
{
// get details from shared preferences
OrderModel orderModel = new OrderModel();
orderModel.setDate(getDate());
orderModel.setName("ssdfs");
orderModel.setEmail("sdf#gmail.com");
orderModel.setNoofitems(String.valueOf(cartlist.size()));
orderModel.setOrderno("32335");
orderModel.setPhone("9896566444");
for(int i=0; i<cartlist.size();i++){
Productdetail pd = new Productdetail();
pd.getSellingprice(String.valueOf(cartlist.get(i).getSellingPrice()));
pd.getPid(cartlist.get(i).getEANCode());
total += cartlist.get(i).getSellingPrice();
orderModel.getProductdetails().add(pd);
}
//
// now go for insertion using retrofit
requestData(orderModel);
Toast.makeText(getApplicationContext(), "Total Price : Rs."+total+"/-", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getApplicationContext(), "Cart is Empty", Toast.LENGTH_LONG).show();
}
}

Retrofit generates the json based on your POJO and set it on the post payload.
So, in this case:
#POST("/apsaratrendz/data/apsara_json_orders_document.json")
Call<Void> setOrder(#Body OrderModel orderModel);
the body of the post will be a json representation of orderModel.
If you need to change the names of the atributtes generated in the json you can use SerializedName Annotation, its very useful:
public class OrderModel {
#SerializedName("other_name_for_json")
private String name;
Hope it helps.
I have a search dialog in my MainActivity that when used sends the user query to a SearchActivity. From there I send a JSON request using volley and then deserialize the JSON using GSON. all of this is working good and I can even print, for an example, the latitude value of my request using:
System.out.println(cam[0].getLat());
However, all of this must be done within the onResponse of the volley request. I'm trying to send some of the values back to my MainActivity which I know how to do already. I just need to know how to store some of the strings so that I can access them outside of onResponse.
Method that sends request and deserializes it:
private void fetchJsonResponse() {
JsonArrayRequest req = new JsonArrayRequest(myUrl, new Response.Listener<JSONArray>() {
#Override
public void onResponse(JSONArray response) {
Gson gson = new Gson();
String nominatimData = response.toString();
NominatimModel[] cam = gson.fromJson(nominatimData, NominatimModel[].class);
// i'd like to using cam[0].getLat(); outside of this method
}
}, new Response.ErrorListener() {
#Override
public void onErrorResponse(VolleyError error) {
// TODO Auto-generated method stub
}
});
mRequestQueue.add(req);
}

I'm fairly new to java and Android development so if someone can help me out a bit i'd appreciate it and if I left out any information let me know.
Figured I'd answer this question now that time has passed and I've learned a ton about Android, including how to accomplish this. So I had all my models implement Serializable, and then just bundled the response data and passed it to the other activity. I later, got rid of this and was able to accomplish everything I needed within the onResponse.
I'd steer away from using Serializable if you must do what I was trying to accomplish and instead check out the Parcelable interface, it has the advantage of being faster.
Hope this helps to anyone who comes across this question!
I have a logical problem to understand, how create a private set of inhabitant object. Here my two classes:
package main;
import java.util.Set;
/**
* #author
* #version 0.1
*
*/
public class City {
private String name;
/**
*HERE is my Problem*/
private Set<Inhabitants> Inhabitants {
}
/**
* standard cunstructor
*/
public City(String n, ) {
setName(n);
}
/**
* Search a particular name of inhabitant
* #return object of inhabitant
*/
static Set<Inhabitants> Search(){
return inhabitants;
}
/**
* Creates a inhabitant object and
* add to the set of inhabitants of the city
*
* #param name
* #param datebirth
* #param maritalStatus
* #
*/
public void Add(String name,String datebirth,String maritalStatus) {
}
/**
* Return all inhabitants objects of the city
* #return
*/
static Set<Inhabitants> ReturnAll(){
return inhabitants;
}
/**
* Return city name
* #return
*/
static Set<Inhabitants> ReturnCityName(){
return inhabitants;
}
/**
* #return the name
*/
public String getName() {
return name;
}
/**
* #param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the inhabitants
*/
public Set<Inhabitants> getInhabitants() {
return inhabitants;
}
/**
* #param inhabitants the inhabitants to set
*/
public void setInhabitants(Set<Inhabitants> inhabitants) {
this.inhabitants = inhabitants;
}
}
package main;
/**

*/
public class Inhabitants {
private String name;

private Boolean maritalStatus;
/**

public Inhabitants() {
}
/**

*/
public String getName() {
return name;
}
/**
* #param name the name to set
*/
public void setName(String name) {
this.name = name;
}
/**
* #return the datebirth
*/
public String getDatebirth() {
return datebirth;
}
/**

It sounds like a simple problem. You didn't need so much code:

this.name = name;
}
public String getName() {
return name;
}
#Override
public boolean equals(Object o) {
if (this == o) return true;
if (o == null || getClass() != o.getClass()) return false;
Person person = (Person) o;
return name.equals(person.name);
}
#Override
public int hashCode() {
return name.hashCode();
}
#Override
public String toString() {
final StringBuilder sb = new StringBuilder("Person{");
sb.append("name='").append(name).append('\'');

Please help me.
Also I do not understand in case I will have many different

What could I do easy and simply?
I mean this case:
<resData>
<data name="crDate">2004-12-17</data>
<data name="exDate">2009-01-02</data>
<data name="password">7fe11fd9d97ee40bdf57e561427c0a6</data>

Thank you Blaise Doughan.
But after dug more over 10 topics I decide I HAD TO to start with opposite way.
I created new test which MARSHALLING my data (objects). Actually, I used TDD (test Driven Development) way I think.
So, I filled up my Objects with test data and applied Marshalling (created XML from DATA) and saw that I got. Data Was Incorrect. I looked to other topic also (thanx this one Java/JAXB: Unmarshall Xml to specific subclass based on an attribute ) and correct my data Structure
remember Id like to get
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<response>
<code>1000</code>
<message>Big message</message>

<data name="svDate">2013.03.14</data>
