Method Details

loadFactoryImplementations

public static <T> List<T> loadFactoryImplementations(Class<T> factoryType)

Load factory implementations of the given type via the SpringFactoriesLoader mechanism.

This method utilizes a custom SpringFactoriesLoader.FailureHandler and DEBUG/TRACE logging that are specific to the needs of the Spring TestContext Framework.

Specifically, this method looks up and instantiates all factoryType entries configured in all META-INF/spring.factories files on the classpath.

If a particular factory implementation cannot be loaded due to a LinkageError or ClassNotFoundException, a DEBUG message will be logged, but the associated exception will not be rethrown. A RuntimeException or any other Error will be rethrown. Any other exception will be thrown wrapped in an IllegalStateException.

Type Parameters:

T - the factory type

Parameters:

factoryType - the interface or abstract class representing the factory

Returns:

an unmodifiable list of factory implementations
