I don’t think so, but it looks to me it’s going to be a good competitor in what it aims to do: dependency injection. I don’t know much about Guice, just heard about it couple of days ago, but the fact that it is coming from Google, it already has good following — at least in the blogoshpere.
Personally, I like it already. I hate writing the Spring’s XML files. I would much rather do it in Java. Guice claims to do that.
Spring is a good framework, no doubt about that. But you should not be too dependent on it. I know that’s not always the case, which is not good.
Drink some juice, I mean guice.
