small footprint dependency injection java

I am looking for a very lightweight dependency injection framework for java.
With minimum possible dependencies and minimum features.

Just something along the following lines: receive a `java.util.List` of `Class`es, instantiate them and just auto-wire all the objects one into the other.

Maybe you should have a look at Google Guice: [

I would recommend [Spring][1], since this can provide a small footprint when using only the core packages.

If you think Spring is overkill, then perhaps [PicoContainer][2], or [guice][3]?

Definitely look into Guice. Been using it for a year, and absolutely love it.

I have been trying [MentaContainer][1] for less than a week now and I am satisfied by its clean and straightforward API. Instead of using XML or Annotations for the setup it uses a fluent API almost like a DSL which for me felt like like heaven because I am using it to build a small web container with IoC support. It provides a THREAD scope for the components which fits perfectly for the REQUEST scope of the web container. It is very lightweight so it may be what you need.

[Silk DI](

) is about `120K` single jar file with no further runtime dependencies. It has a fluent binder interface like guice but is more flexible and allows to remove features you don't like. E.g. `Collection` or `List` injection can be added in a *one liner*.

Take a look at dagger2, developped at google (forked of square's dagger1), for only 17kb jar.

+ Much less boilerplate than guice
+ compile time verification of injection (with explicit error message. That's something spring, guice does definitly not)
+ generate Facotries, codes upon compile. **Very powerfull**
