Get servletcontext for factory class in spring

Question

Hi ...,

I want to create Factory Class. for example is FooFactory. before Foo instanced, FooFacoty must be injected ServletContext to the constructor. I have snippet as follows:

public class FooFactory() {
    public static Foo getFoo() {
        ctx = //getservlet context
        Foo foo = new Foo(ctx);

            return foo;
    }
}
