У меня есть простой тест с использованием Spring Data MongoDB для сохранения объекта в хранилище и последующего его считывания. Проверка не удалась, потому что, когда я пытаюсь прочитать содержимое объекта, входной поток не возвращает никаких данных, даже через объект GridFsResource, говорит, что размер составляет 33 байта (это правильно).
РЕДАКТИРОВАТЬ : Я создал новый проект из spring boot initializr .... maven / java 8 / boot 2.2.5, единственной зависимостью является Spring Data Mon go DB. После загрузки я добавил только тестовый документ к ресурсам теста и один метод тестирования. По-прежнему не удается.
EDIT2: обновлен пример проекта для использования в памяти mon go сервера. Ссылка для скачивания.
Вот мой простой тестовый пример:
@Test
public void test_getDocument() throws Exception {
Resource resource = new ClassPathResource("grid/testDocument.txt");
String fileContent = "This is a Test Document";
ObjectId reference = gridFsOperations.store(resource.getInputStream(), "foo.txt");
List<GridFSFile> files = new ArrayList<>();
GridFSFindIterable result = gridFsOperations.find(new Query(Criteria.where("_id").is(reference)));
result.into(files);
assertEquals(1, files.size());
assertEquals(reference, files.get(0).getObjectId());
GridFSFile fsFile = files.get(0);
assertEquals("foo.txt", fsFile.getFilename());
GridFsResource fsResource = new GridFsResource(fsFile);
assertEquals(fsFile.getLength(), fileContent.length()); // This test passes.
String fileValue = StreamUtils.copyToString(fsResource.getInputStream(), StandardCharsets.UTF_8);
assertEquals(fileValue, fileContent); // This test fails
}
