Мобильная версияjsr 330, согласно этому руководству: < /p>
maven di - это структура впрыскивания зависимости Maven, которая вводится в Maven 4. < /p>
Это преемник для Plexr Ioc (используемый в Maven 2330 и JSRIPSE 2330 и JSRIPSIPSE 230 и JSRIP. SISU (используется в Maven 3) в Maven.
Из того, что я могу сказать, с новыми API есть два способа получить услуги:
- Инъекция зависимости с новым @org.apache.maven.api.di.injecte Inject A Session , а затем Call Session :: Getservice (Class) .
те же услуги при использовании в проекте. И наоборот, получение услуг через Session :: GetService < /code> не удается во время
модульных тестов, но добивается успеха при использовании в проекте. Таким образом, не только получение услуг, по -видимому, имеет различное поведение
между тестами и «производством», но и различные API, которые «делают одно и то же», терпят неудачу в противоположных точках. Я нахожу это довольно странным. Я бы ожидал, что либо GetService будет намного более надежным, чем DI, либо GetService и @Inject
в конечном итоге использует ту же реализацию под капюшоном (что означает, что они должны вести себя то же самое).
Что я делаю неправильно? Должен ли я даже проверить модос для моджного тестирования? Кроме того, желание вводить услуги должно быть обычным явлением
, поэтому я предполагаю, что это хорошо протестированная особенность. < /P>
Я предполагаю, что проблема в том, как модульные тесты «проводятся». Я не верю, что версия Java имеет значение, если это Java 17+.
