This is the method in my service. I get the Exception when .stream.map.collect
#Override
public GameDto save(GameRequestDto gameRequestDto) {
Optional<Game> gameOptional = gameRepository.findByTitleAndStudio(gameRequestDto.getTitle(),
gameRequestDto.getStudio());
if (gameOptional.isPresent()) {
throw new InvalidRequestException("Game with title: " + gameRequestDto.getTitle() +
" and studio: " + gameRequestDto.getStudio() + " already exists.");
}
Game gameToBeSaved = buildGameToBeSaved(gameRequestDto);
Game savedGame = gameRepository.save(gameToBeSaved);
GameDto gameDto = gameMapper.gameToGameDto(savedGame);
gameDto.setGameGenres(savedGame.getGenres().stream()
.map(Genre::getGenreName)
.collect(Collectors.toCollection(HashSet::new)));
return gameDto;
}
This is my Test
#InjectMocks
GameServiceImpl gameService;
#Mock
GameRepository gameRepository;
#Mock
GenreRepository genreRepository;
#Test
public void saveGameTest() throws Exception {
Set genres = new HashSet<>();
genres.add("Role Playing");
Game savedGame = buildGame(genres);
Mockito.when(gameRepository.save(any(Game.class))).thenReturn(savedGame);
gameService.save(buildGameRequestDto(genres));
Mockito.verify(genreRepository, Mockito.times(4));
Mockito.verify(gameRepository, Mockito.times(1));
}
And this is the Exception
java.lang.ClassCastException: class java.lang.String cannot be cast to class com.home.myproject.entities.Genre (java.lang.String is in module java.base of loader 'bootstrap'; com.home.myproject.entities.Genre is in unnamed module of loader 'app')

When I run test then it failed at this point ReflectionTestUtils.setField(service, SeRepositoryImpl.class, "isBoolean",true,Boolean.class) complains about Could not find field 'isBoolean' of type not found. Error trace as below.
I am not sure why because my repositoryImpl class has isBoolean variable defined.

I have corrected my question. I've pasted all the code here that pertains to my question. For starters, I would like to simply output the Query result of the repository to the console. But in the form that I just posted here, I get a NullPointerException error and says that in a part of the code: controller.saveSum (); - controller = null.
Create a PaymentService class which should contain the method getTotalPayment. Inject this class in EmailSend (tip: please change this class name from EmailSend to EmailSender as class names should be noun) class. And then in PaymentService Class you should interact Data Repository class. Call this getTotalPayment method from the EmailSend class.
#Component
public class TempTry implements CommandLineRunner{
#Autowired

System.out.println("For email " + mail + " UUID=" + uuid + " is stored at time " + new Date());
System.out.println("UUID generated from String is " + fromString);
}
}
I set run configuration as -e dhanrajtijare#gmail.com ..getting email value as expected.
My problem here is at line tkeRepo.save(tknEntity); tkeRepo is null
Here
TempTry main = new TempTry();
How do you expect #Autowire to work if you are creating instance yoursefl?
Your current instance seems to be in app context by that point, so
#Override
public void run(String... args) throws Exception {
logger.info("ApplicationStartupRunner run method Started !!");
JCommander.newBuilder().addObject(this).build().parse(args);
runtask();
}
I put aside the fact that IMHO its just bad to mix JCommander with Spring CLI - use either one or another.

Everything should work correctly.
The problem, obviously, that List listOfFriends is List<String>, not List<Object[]>. It is strange, because of Select name,presenceStatus from UserPresence should return List<Object[]>.
Maybe Spring set an incorrect implementation of #Autowired
private DetailsDao detailsDao;.
Try this code. This should work for List<String>
private List<FriendsDetails> fetchListOfFriendss(List<?> genericList) {
Iterator<?> itr = genericList.iterator();
List<FriendsDetails> listOfFriend = new ArrayList<FriendsDetails>();
while (itr.hasNext()) {
Object obj = itr.next();
String userName = String.valueOf(obj);
System.out.println(userName);
FriendsDetails obj1 = new FriendsDetails();
obj1.setFriendName(userName);
listOfFriend.add(obj1);
}
return listOfFriend;
}
