Class 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:

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