For the first time, a service is required, Service Locator looks up in JNDI and caches the service object. The service locator pattern is different from dependency injection in the way the elements are consumed. In this article I will show you how we can solve a problem using factory method and strategy pattern using spring service locator. Nevertheless in a particular scenario, I can't determine which implementation to be used until run-time. The other pattern you can use to do this is Service Locator, and I'll discuss that after I'm done with explaining Dependency Injection.
