## Class SpringFactoriesLoader

- java.lang.Object
- - org.springframework.core.io.support.SpringFactoriesLoader

-     public abstract class SpringFactoriesLoader
      extends Object

  General purpose factory loading mechanism for internal use within the framework.

  The `SpringFactoriesLoader` loads and instantiates factories of a given type from "META-INF/spring.factories" files. The file should be in `Properties` format, where the key is the fully qualified interface or abstract class name, and the value is a comma-separated list of implementation class names. For instance:

      example.MyService=example.MyServiceImpl1,example.MyServiceImpl2

  where `MyService` is the name of the interface, and `MyServiceImpl1` and `MyServiceImpl2` are the two implementations.

    - #### loadFactories

          public static <T> List<T> loadFactories(Class<T> factoryClass,
                                                  ClassLoader classLoader)

      Load the factory implementations of the given type from the default location, using the given class loader.

      The returned factories are ordered in accordance with the `OrderComparator`.

      Parameters:
        `factoryClass` - the interface or abstract class representing the factory
        `classLoader` - the ClassLoader to use for loading (can be `null` to use the default)

    - #### loadFactoryNames

          public static List<String> loadFactoryNames(Class<?> factoryClass,
                                                      ClassLoader classLoader)
