Year After Switching from Java to Go: Our Experiences
Never really heard of Dagger before, but I love what I'm seeing: https://dagger.dev/
On the other hand, using DI with Spring is both powerful and really annoying when things blow up due to unsatisfied dependencies, I'd much rather see that at compile time, so Dagger seems right up my alley! Thanks for mentioning it!

Dependency Injection in Go: Comparing Wire, Dig, Fx & More
Dagger is a compile-time dependency injection tool widely used in Java and Kotlin. Although not officially supported in Go, some developers have experimented with using it.
- Dagger 2.49 (KSP, @AssistedInject with @HiltViewModel, more)
- Dagger 2.48 adds alpha KSP support
- Dagger KSP update & Breaking changes required to use Dagger KSP

Performance and memory impact of the @Singleton annotation in Dagger
There used to be a thing called "releasable references" which was that. It was removed, though: https://github.com/google/dagger/issues/1117

Dependency injection with AWS Lambdas in java
As said in the title, we will focus on the dependency inversion principle and one of its application : dependency injection. For production-ready applications, it would be better to rely on a framework and not implement its own container. For it, the java ecosystem have 3 frameworks available : Spring, Guice and Dagger.

Refactoring our Dependency Injection using Anvil
At Reddit, we use Dagger 2 for handling dependency injection (DI) in our Android application. As we’ve scaled the application over the years, we’ve accrued a bit of technical debt in how we have approached this problem.

I've been using CDI for something like this. The project is temporarily hosted here.

Show HN: I finished v5 of a JVM framework I've spent spent half a decade making
Any DI lib would probably work, it depends on your preferences and use cases though.
I'm personally a fan of Weld since its the reference implementation of the CDI spec.

- Weld 5.0.0.Beta1 released!

Non Spring users what are you using ??
Need only Dependency injection? Perhaps JBoss Weld, a reference CDI implementation, might interest you.
What are some alternatives?
When comparing Dagger2 and Weld you can also consider the following projects:
Guice - Guice (pronounced 'juice') is a lightweight dependency injection framework for Java 11 and above, brought to you by Google.
Apache DeltaSpike - Mirror of Apache Deltaspike
HK2
Toothpick - A scope tree based Dependency Injection (DI) library for Java / Kotlin / Android.
