Spring throwing HttpMediaTypeNotAcceptableException: не удалось найти приемлемое представление из-за точки в URL-адресе

Финальное редактирование

Итак, после изучения этого, потому что ответ не совсем сделал, так как с тем, что я видел, я обнаружил, что Spring делает некоторые странные вещи с расширением соответствия. Если я отправлю запрос, подобный этому byNameOrAtlName/myStringHere.1 или этому byNameOrAtlName/myStringHere.12, все будет в порядке, но byNameOrAtlName/myStringHere.123 заставляет его ломаться, как и byNameOrAtlName/myStringHere.com, но byNameOrAtlName/myStringHere.co в порядке, но byNameOrAtlName/myStringHere.c нет.

В общем, я не знаю, что использует логика Spring для определения материала расширения, но для определенных расширений {varName:.+} работает как своего рода работа, но похоже, что вам нужно полностью отключить суффикс точечного файла чтобы действительно обойти это.

Использование Spring 4.1.6

Spring выбрасывает следующее исключение org.springframework.web.HttpMediaTypeNotAcceptableException: Could not find acceptable representation

У меня есть следующий код, и все работает, если строка (имя) не имеет в ней периода.

@RestController
@RequestMapping(value = "/foo/")
public class Testing{
    @RequestMapping(value = "byNameOrAltName/{name:.+}", method = RequestMethod.GET)
    @Transactional(readOnly = true)
    public Collection<MyDTO> getByNameOrAltNAme(@PathVariable("name") String name) {
        return myRepo.getMyDTOsByNameOrAtlName(name);
    }
}

Итак, это работает. http://localhost:8080/data/foo/byNameOrAtlName/myStringHere, но если я это сделаю, он терпит неудачу http://localhost:8080/data/foo/byNameOrAtlName/myStringHere.fluffy

Я прочитал другие ответы вокруг этого исключения, но ни один из них, похоже, не применим к моему делу. И сначала я подумал, что это проблема, когда Spring не любит, чтобы период находился в пути, и я исправил это раньше с помощью регулярного выражения .+, но я попробовал его как с регулярным выражением, так и без него, и я получаю то же самое ошибка.

Любые идеи относительно того, почему Spring выбрасывает это?

ОТВЕТЫ

Ответ 1

Spring обрабатывает часть после точки в качестве суффикса файла, чтобы попытаться определить, какой тип ответа вы действительно хотите. Здесь - достойная запись в согласовании содержимого в Spring.

Так что происходит, что Spring пытается представить результат в типе контента, к которому он не может найти конвертер.

Чтобы решить эту проблему, вам нужно сообщить Spring об отключении суффикса на основе содержимого:

@Configuration
public class ContentNegotiationConfig extends WebMvcConfigurerAdapter {
    @Override
    void configureContentNegotiation(final ContentNegotiationConfigurer configurer) {
        // Turn off suffix-based content negotiation
        configurer.favorPathExtension(false);
    }
}

Update:

Я вырыл немного глубже, и я думаю, что могу объяснить, что происходит.

Конфигурация по умолчанию игнорирует неизвестные суффиксы пути, поэтому для объяснения этого нам нужно знать, как Spring определяет, что суффикс пути неизвестен и что сводится к этому фрагменту кода в PathExtensionContentNegotiationStrategy:

@Override
protected MediaType handleNoMatch(NativeWebRequest webRequest, String extension)
        throws HttpMediaTypeNotAcceptableException {

    if (this.useJaf) {
        MediaType jafMediaType = JafMediaTypeFactory.getMediaType("file." + extension);
        if (jafMediaType != null && !MediaType.APPLICATION_OCTET_STREAM.equals(jafMediaType)) {
            return jafMediaType;
        }
    }
    if (!this.ignoreUnknownExtensions) {
        throw new HttpMediaTypeNotAcceptableException(getAllMediaTypes());
    }
    return null;
}

Итак, что происходит, вероятно, что Java Activation Framework распознает некоторые ваши суффиксы и возвращает для них тип носителя. Расширение .c, вероятно, возвращает текст /x -c, поскольку это вызывает исключение.
