I'm a .NET developer primarily but am looking to use IoC in a Java project.
I have strong familiarity with Autofac. Is there an IoC container for Java that is substantially similar to Autofac in the way it is built, configured, etc.?
I don't think there is anything similar. Autofac is quite unique and rely strongly on lambdas.
I could only recommend you google guice, which is more similar to ninject. IMO it's quite powerful, easy to pick and fun to code.
