MEF (.NET) analogue for Java

I got very used to this clean syntax with MEF in .NET

[Export(typeof(ISomething))]
public class Something : ISomething {
}

Is there any analogy with annotations in Java? (& corresponding framework). Any dependency injection containers to be good compatible with?

From what I could find to the moment, I can use Google Guice with its annotations. There (in G.G.) they specify default implementer of interface rather then doing export of implementation (as in MEF). E.g.

@ImplementedBy(Something.class) 
public interface ISomething {
    ...
}

public class Something implements ISomething {
    ...
}

Constructor parameters injections etc are also somewhat possible from documentation.

There are several IoC containers available in Java. The two that comes to my mind are Spring with its IoC Container and Google Guice.

I have mostly worked with Spring IoC and find it very nice to work with.

Here is another good tutorial regarding Spring IoC.
