Попытка модульного тестирования получения страницы из весенней загрузки. При использовании Javascript страницу можно легко десериализовать, но при использовании Java это не удается. Добавил конструктор по умолчанию для Spring (это принятый ответ в другом сообщении stackoverflow), но здесь он не работает.
Юнит-тест
@Test
public void test_read_pagination_happy(@Autowired ObservationSet set) {
repository.save(set);
final HttpEntity authHeaders = authentication.convert("", authSuccess);
final ParameterizedTypeReference responseType = new ParameterizedTypeReference() {
};
// final ResponseEntity result = restTemplate.exchange(base + "/api/v1/observationset", HttpMethod.GET, authHeaders, String.class);
final ResponseEntity result = restTemplate.exchange(base + "/api/v1/observationset", HttpMethod.GET, authHeaders,
responseType);
System.out.println(result.getBody());
assertSame(HttpStatus.OK, result.getStatusCode(), "incorrect status code");

При десериализации выдается следующая ошибка:
