I'm trying to parse the json from the api http://badiyajobs.com/apis/v1/rolesbut response.isSuccess is returning false
my modal class is,
package arpit.retrodemo;
import java.util.List;
import java.util.ArrayList;
public class Modal {
private List<RolesEntity> roles = new ArrayList<>();
public void setRoles(List<RolesEntity> roles) {
this.roles = roles;
}
public List<RolesEntity> getRoles() {
return roles;
}
public static class RolesEntity {
private String id;
private String role;
private String description;
private String icon_url;
private String created_at;
private String updated_at;
public void setId(String id) {
this.id = id;
}
public void setRole(String role) {
this.role = role;
}
public void setDescription(String description) {
this.description = description;
}
public void setIcon_url(String icon_url) {
this.icon_url = icon_url;
}
public void setCreated_at(String created_at) {
this.created_at = created_at;
}
public void setUpdated_at(String updated_at) {
this.updated_at = updated_at;
}
public String getId() {
return id;
}
public String getRole() {
return role;
}
public String getDescription() {
return description;
}
public String getIcon_url() {
return icon_url;
}
public String getCreated_at() {
return created_at;
}
public String getUpdated_at() {
return updated_at;
}
}
}
Sample json is,
{"roles":[
{
"id":"1",
"role":"Retail Sales Executive",
"description":"As a sales assistant....",
"icon_url":"",
"created_at":"2015-10-02 12:03:03",
"updated_at":null
}
]
}
APIService.java is,
package arpit.retrodemo;
import retrofit.Call;
import retrofit.http.GET;
public interface APIService {
#GET("/roles")
Call<Modal> getDetails();
}
MainActivity.java is,
package arpit.retrodemo;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import java.util.ArrayList;
import java.util.Iterator;
import java.util.List;
import retrofit.Call;
import retrofit.Callback;
import retrofit.GsonConverterFactory;
import retrofit.Response;
import retrofit.Retrofit;
public class MainActivity extends AppCompatActivity {
private static final String ENDPOINT = "http://badiyajobs.com/apis/v1";
private APIService service;
private Modal mod;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Retrofit retrofit = new Retrofit.Builder()
.addConverterFactory(GsonConverterFactory.create())
.baseUrl(ENDPOINT)
.build();
service = retrofit.create(APIService.class);
Call<Modal> userList = service.getDetails();
userList.enqueue(new Callback<Modal>() {
#Override
public void onResponse(Response<Modal> response) {
if(response.isSuccess()){
Log.d("findRes", response.body().toString());
}else{
Log.d("find", "Something is wrong! " + response.errorBody().toString());
}
}
#Override
public void onFailure(Throwable t) {
Log.d("findError", t.getMessage());
}
});
}
}
Here i'm getting the following on logcat,
D/find: Something is wrong! com.squareup.okhttp.ResponseBody$1#52715c98
instead of the string representation of response.body()
You need to do the following:
public interface APIService {
#GET("roles") /*removed the / here */
Call<Modal> getDetails();
}
private static final String ENDPOINT = "http://badiyajobs.com/apis/v1/"; /* added the / here */

I am working on the CRUD rest API and application is turning on but when I'm trying to make a post request there is a: "status": 404, "error": "Not Found". On the postman, I also add header content-type: application/JSON and requesting at URL: http://localhost:8080/tickets.
Do you know guys how to fix this?
Here is the code.

im trying to make a post request at postman and getting 404 error
Have you specify the POST method in Postman ?
And the body of your request ?
Postam sample
I'm trying to create a route to perform a GET Request to /winner to show the restaurants that had the count of 3 votes in the JSON, but every time I do the GET, it returns the value of null instead of the value I would like.
I was expecting something like that:
{
"id": 1,
"restaurant": "Burger King",
"address": "Av. Ipiranga, 1600",
"website": "https://www.burgerking.com.br/",
"description": "Rede de fast-food famosa com hambúrgueres grelhados, batata frita e milk-shakes.",
"count": 3
}
Instead that, I'm just getting an empty JSON with the null value.

you didn't access dao in the method findWinner.
restaurants instance has just created without accessing dao.
#Transactional(readOnly = true)
public Restaurant findWinner(Integer count) {
List<Restaurant> restaurants = new ArrayList<>();
for (Restaurant restaurant: restaurants) {
if(restaurant.getCount().equals(3)) {
return restaurant;
}
}
return null;
}
because in the find winner method you have initialized restaurants with an empty array list.
It should be like this.
#Transactional(readOnly = true)
public Restaurant findWinner(Integer count) {
List<Restaurant> restaurants = repository.findAll();
for (Restaurant restaurant: restaurants) {
if(restaurant.getCount().equals(3)) {
return restaurant;
}
}
return null;
}
Failed to receive body from response. i used php as back end server in android using Retrofit . in my every project i used retrofit but this time i failed getting response body from server i don't know where is the problem.
I search all over the internet but i failed to get out myself from the problem. in below i put all of my code. Thanks you a lot in advance

}
}
You seem to be wrong in the attributes you parse. I expect that from this line:
Log.d("VIDEOLINK", "onResponse: "+link);
You get the output
"onResponse: null"
Correct your SerializedName definitions:
#SerializedName("name")
#Expose
private String categoryName;
#SerializedName("link")
#Expose
private String videoLink;
I am basing my answer on what I see as response from your API.

jsonArray.put(data);

}
In your test class, what you must do is separate the test data creation to a different class and pass that as data provider to your test method. This is from design point of view.
Coming to your problem:
You are already using gson, why are you constructing a JSONObject. Instead do something like below;
Gson gson = new Gson();
String _my_obj = gson.toJson(example);
Hope this is what you are looking for.
A similar question with a different issue has been answered before. I have a bidirectional #ManyToMany relationship using Hibernate. The data persists to the separate entity tables, but the id column that maps to the entity tables is empty. I have tried the suggestions in Empty Join Table resulting from JPA ManyToMany, ManyToMany relationship, deleting records from relationship table and Hibernate Many-to-many association: left hand side collection contains elements, but right hand side collection is empty, but have not had success so far. Below is my code for completeness (I am still learning java and the spring framework, so I apologise for any rookie mistakes in advance):

I have tried deleting the database and creating it again, but it hasn't solved the problem so far.
Below is the code for persisting the data to the database

I am able to get data populated to the join table, but it seems to populate endlessly. It happens when the water quality data is added.
It is not clear in code posted, how you are trying to save associated entity. You should persist like this...
WaterQuality waterQuality = new WaterQuality();
//Set other fields too
CaseStudy caseStudy1 = new CaseStudy();
CaseStudy caseStudy2 = new CaseStudy();
CaseStudy caseStudy3 = new CaseStudy();
CaseStudy caseStudy4 = new CaseStudy();
//Set other fileds of case study too
List<CaseStudy> caseStudyList = waterQuality.getCaseStudyList();
caseStudyList.add(caseStudy1);
caseStudyList.add(caseStudy2);
caseStudyList.add(caseStudy3);
caseStudyList.add(caseStudy4);
waterQualityService.save(waterQuality);
If you will assign WaterQuality objects to CaseStudy Entity and save CaseStudy, then associations won't be populated in JoinTable.
And one more important thing, use Set instead of List for Collection.In case of List, Suppose, You already have 100 case study for waterQuality and if you want to delete one of them, Then it will delete entire case studies first and then add all case study again except the deleted one. Use Set if your collection does not contain duplicates. If your collection contains duplicates too, Then use List with index.
