spring boot crud api receive 404 error from post request: postman

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 ?

Return key value of a JSON request in Spring

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;
}

Your request has to match the #RequestBody object for spring to map the keys appropriately
Try this request -
{
"id":19,
"name":"Alex",
"address":{
"cityname":"california",
"streetname":"ring road",
"Housename":"Housename"
}
}

Please make sure you give input as per your Model.

Unable to fetch json object and array in Retrofit 2

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 */

How to Mock an object which is created in the class under test in Mockito

I need to mock an object which is instantiated from the method under test. Please check the below code for your reference.
Class Under Test:
package org.sambaran.model;
import java.util.List;
public class Book implements Item {
private String isbn;
private String title;
private String description;
private List<Author> authors;
private BSOInterface bsoInterface;
public Book(String isbn, String title, String description,
List<Author> authors) {
super();
this.isbn = isbn;
this.title = title;
this.description = description;
this.authors = authors;
}
public String getIsbn() {
return isbn;
}
public void setIsbn(String isbn) {
this.isbn = isbn;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getDescription() {
return description;
}
public void setDescription(String description) {
this.description = description;
}
public List<Author> getAuthors() {
return authors;
}
public void setAuthors(List<Author> authors) {
this.authors = authors;
}
public void createBook(){
bsoInterface=new BSOInterfaceFactory().getBSOInterface();
bsoInterface.createBook(this);
}
}
This is the test class:
package org.sambaran.model.test;
import static org.junit.Assert.assertEquals;
import static org.junit.Assert.assertNotNull;
import static org.junit.Assert.fail;
import java.util.ArrayList;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
import org.mockito.Mock;
import org.mockito.Mockito;
import org.sambaran.model.Author;
import org.sambaran.model.BSOInterface;
import org.sambaran.model.Book;
import org.sambaran.model.Item;
public class BookTest {
#Mock
BSOInterface bsoInterface;
Item b;
#Before
public void setUp() throws Exception {
b=new Book("123-654-6789", "Head First C", "First Book on C", new ArrayList<Author>());
}
#After
public void tearDown() throws Exception {
}
#Test
public void testGetIsbn() {
assertNotNull(b.getIsbn());
}
#Test
public void testSetIsbn() {
String isbn="111-222-3333";
b.setIsbn(isbn);
assertEquals(b.getIsbn(), isbn);
}
#Test
public void testGetTitle() {
Book book=Mockito.mock(Book.class);
assertNotNull(book.getDescription());
}
#Test
public void testCreateBook(){
/**
* Here I need to mock the bsoInterface but the object is created in this method only.
*/
b.createBook();
}
#Test
public void testSetTitle() {
fail("Not yet implemented");
}
#Test
public void testGetDescription() {
fail("Not yet implemented");
}
#Test
public void testSetDescription() {
fail("Not yet implemented");
}
#Test
public void testGetAuthors() {
fail("Not yet implemented");
}
#Test
public void testSetAuthors() {
fail("Not yet implemented");
}
}
During testing createBook() I need the bsoInterface object which I need to mock. Can you please let me know how to do this?

Just create one more method that gets BSOInterfaceFactory as parameter. You can use the second one in tests.
public void createBook(){
create(new BSOInterfaceFactory());
}
public void create(BSOInterfaceFactory bsoInterfacefactory) {
this.bsoInterface=bsoInterfacefactory.getBSOInterface();
bsoInterface.createBook(this);
}
and the test should look like:
#Test
public void testCreateBook(){
BSOInterfaceFactory bsoInterfaceFactory = mock(BSOInterfaceFactory.class);
b.createBook(bsoInterfaceFactory);
}
