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.
