Dependency Injection and Service Locator, two different ways to implement Inversion of control principle.
A dependency injector container acts as an assembler of objects, decoupling your business logic from their dependencies. But sometimes is more complex to debug when we have a issue.
On the other hand, Service Locator hides the implementation details too, but your class has dependency with the Service Locator class. Only, when this dependency is not a problem, the Service Locator pattern is a good choice.
Most important of all, is to split the configuration code from the use code. Take it into account , and analyze when one option is better than the other.
Until next post!
