It is but there isn't a heavy emphasis on a DI framework per se. At its core DI is "inversion of control" insofar as an object constructor receives what it needs to do its job as opposed to the constructor instantiating said requirements itself. In my experience Golang devs don't use of a bunch of meta-programming via tags/annotations/decorators to tell a third-party framework what reflect-y magic it has to do at runtime; they typically just abstract everything behind an interface and pass instances of what you need to a New function that instantiates the consumer object. I personally prefer this to Spring-type frameworks because it's more verbose and checked at compile time. This means one can easily follow what's going on instead of having to dig through a bunch of nested stack traces riddled with Aspect4J esoterica to find out why some magical Maven dependency suddenly broke your entire app for no reason at all.
Then again the last time I had to bootstrap a complex Spring project was in 2014. Since then I've used Spring Boot for simple 3-tier microservices and it worked fine... it's likely improved since then but I still wouldn't use it for anything greenfield after the loop it threw me for.
