Why is that happening?, cant I block value or is it something wrong with post code? I am totally new to this reactive abstracion, such implementation of WebTestClient post worked with non reactive approach. Here is code that fails:
Here postAndVerify fails:
@ExtendWith(SpringExtension.class)
@SpringBootTest(webEnvironment = RANDOM_PORT, properties = {"spring.data.mongodb.port: 0"})
public class MovieServiceApplicationTests {
@Autowired
WebTestClient webTestClient;
@Autowired
MovieRepository movieRepository;
@Test
public void getMovie() {
Integer given = 1;
postAndVerify(given, HttpStatus.OK);
getAndVerify(given, HttpStatus.OK)
.jsonPath("$.movieId").isEqualTo(given)
.jsonPath("$.genre").isNotEmpty()
.jsonPath("$.title").isNotEmpty()
.jsonPath("$.address").isNotEmpty();
}
private WebTestClient.BodyContentSpec postAndVerify(Integer id, HttpStatus httpStatus) {
Movie movie = Movie.builder()
.movieId(id)
.title("Title for movie " + id)
.genre("Genre for movie " + id)
.address("Address for movie " + id)
.build();
return webTestClient.post()
.uri("/movie")
.body(Mono.just(movie), Movie.class)
.accept(MediaType.APPLICATION_JSON_UTF8)
.exchange()
.expectStatus().isEqualTo(httpStatus)
.expectHeader().contentType(MediaType.APPLICATION_JSON_UTF8)
.expectBody();
}
}
And implementation of create method looks like this:
@Override
public Movie createMovie(Movie movie) {
MovieEntity movieEntity = movieMapper.apiToEntity(movie);
Mono<Movie> movieMono = movieRepository.save(movieEntity)
.onErrorMap(DuplicateKeyException.class, ex -> new InvalidInputException("Duplicate key for movieId: " + movie.getMovieId()))
.log()
.map(movieMapper::entityToApi);
return movieMono.block();
}
