We have a good time with it in our work. We don't use everything it has to offer, but we do use dependency injection, Spring MVC and JMS. We write testable classes, we new them up in @Bean methods and group them together in @Configuration classes. Everything is modular - you want to use our in-process message bus? Just @Import the configuration class. You want to include Jetty and use MVC? Just @Import the configuration class, you can set a couple of properties and authentication is enabled using our in house SSO. I think modern Spring lends itself very well to making services this way, if you can make the effort to make your application components modular, you can reuse the common stuff and have it interface nicely with the service specific code.
