Why use spring?

Question

 I am very confused if I should use spring

Cause. I want to develop loosely coupled code, which I think can be developed using the Factory template and interfaces ... and dependency injection can be implemented without using spring too ... (by passing parameters) .. why am I using spring, then? ? What are the other benefits of spring that I don’t know about ... It would be very helpful if you could give me some code examples comparing spring codes and simple java code (interfaces) ... indicates how best spring code is ...

thank
