Service Locator Factory Pattern

The Service Locator Factory pattern helps locate services at runtime based on specific criteria. This guide focuses on implementing Spring's service locator pattern to avoid boilerplate code and enhance efficiency. The example provided demonstrates building a payment system with different payment processors (Visa, Amex) by using components such as Client, Service Locator, Initial Context, and Service Factory. The key takeaway includes reducing tight coupling and the need for boilerplate code for service management.
