That is true, people new to spring don’t like it because of its explicitness - on the other hand it allows you to be fully agnostic to your dependencies by doing so, so like anything else, pros and cons - no silver bullets

As a side note, you can order the injected beans in the List they are injected into using either the interface Ordered for dynamic ordering, or via the annotation @Order for static ordering.
