Этот запрос может привести к возвращению нулевых рядов, но, поскольку это выбранное запрос, resultset.next () < /code> все еще должен работать, возвращая false.
мы видим То же самое с другими запросами, которые потенциально возвращают 0 строк.
У нас есть несколько тестов для этого (работа с базой данных MySQL в TestContainer), которые также проверяют на наличие NULL < /code> case < /p>
@Test
internal fun `test fetch by auth token for unknown user`() {
val principal = springUserRepository.fetchPrincipalByIdAndAuthToken(
userId = 90210,
token = "auth",
)
assertThat(principal).isNull()
}

Странная вещь в том, что большую часть времени все работает отлично. Это кажется довольно случайным, и что не помогает, так это то, что мы не можем найти никаких подобных проблем на Google или на этом сайте. Чтобы вызвать ошибку, выполнив тест нагрузку в среде разработки. К сожалению, это не вызвало ошибку. Они указывают на то, что не видели никаких баз данных или сетевых ошибок во времена, когда возникла проблема.
