jakarta library

The standard Java injection names, for code that prefers them to the Spring ones: the JSR-330 Provider<T> (a bean looked up on each use) and the JSR-250 annotations @Resource (inject by bean name) and @Priority (rank beans of one type).

They are not part of spring_core_dart.dart because their names clash: Provider with package:provider, Resource with this package's own resource type. Import this library on its own, with a prefix where a name clashes. Applications that use ObjectProvider, @Autowired, @Qualifier and @Order do not need it.

import 'package:spring_core_dart/jakarta.dart' as jakarta;

@Service()
class Reports {
  // Two stores exist; the archive one is wanted here.
  @jakarta.Resource(name: 'archiveStore')
  late final Store store;
}

Classes

Priority

Ranks a bean among others of the same type: the JSR-250 annotation jakarta.annotation.Priority, on a bean class (or @Bean method).

Provider<T extends Object>

A handle that looks up a bean of T each time get is called: the JSR-330 form of a lazy dependency (jakarta.inject.Provider).

Resource

Injects a field or setter with the bean of a given name: the JSR-250 annotation jakarta.annotation.Resource.
