В Play's application.conf у меня есть несколько конфигов для моего приложения.Например:
pew.server-script {
python {
exec = "python {1}"
filename = "{1}.py"
}
}
Во время миграции Play с 2.6.20 на 2.7.0 я обнаружил, что мои тесты не работают, потому что сценарий pew.server отсутствует в Config.Это пример теста:
private final Application application = prepareApplication();
static Application prepareApplication() {
Map<String, Object> additional = new HashMap<>(inMemoryDatabase("prototype"));
// skipped
additional.put("pew.scriptsFolder", "example");
// skipped
return new GuiceApplicationBuilder()
.overrides(Bindings.bind(HttpExecutionContext.class).to(
() -> new HttpExecutionContext(ForkJoinPool.commonPool())
))
.configure(ConfigFactory.parseMap(additional))
.build();
}
@Test
public void regAndLogin() {
running(application, () -> {
registerUser(application);
Http.RequestBuilder request = fakeRequest()
.method(GET)
.host("localhost")
.header("Authorization", basicKey)
.uri("/user/test");
Result result = route(application, request);
assertEquals(OK, result.status());
});
}
Сбой при инициализации модуля при вызове GuiceApplicationBuilder.build ():
bind(ConfigService.class).asEagerSingleton();
ConfigService выглядит следующим образом:
@Singleton
public class ConfigService {
private Config config;
// skipped
@Inject
public ConfigService(Config config) {
this.config = config;
decodeSettings();
}
@SuppressWarnings("unchecked")
private void decodeSettings() {
Map<String, Map<String, String>> cfg = (Map<String, Map<String, String>>) config.getAnyRef("pew.server-script");
// skipped
}
// skipped
}
За этим исключением:

Также происходит сбой Akka во время создания маршрутизатора с настройками из config и JPA - необходимые настройки не включены в Config.Я проверил с отладкой IntelliJ IDEA - из "pew" в экземпляре Config есть только pew.scriptFolder = "example", который был установлен в дополнительной конфигурации (функция prepareApplication()).Я также попробовал это:
.configure(ConfigFactory.parseFile(new File("conf/application.conf")).resolve())
Но это приводит к краху Config, ApplicationLifecycle, Environment, инъекция конфигурации.Как получить настройки ввода из application.conf в Application?
