Spring I/O 2017 - 18 -19 May, Barcelona Slides: https://docs.google.com/presentation/d/1CRjAKdQEvVNi9JzuudEKlnncJffKi5k8Lw0J335IYMk/edit?usp=sharing The bigger a monolithic application, the larger the dependency set. Adding or changing dependencies becomes a tricky task. Similarly, the complexity is in a number of beans and their dependencies in components container. In this talk, we’ll discuss a way to simplify things by splitting component containers into smaller ones. We’ll see how to split a monolithic ApplicationContext into a number of sub-contexts, how to isolate sub-context internal beans, clear their APIs and avoid non-trivial dependencies. Each sub-context can have its own classpath, which tackles the dependency hell problem. After being divided, a monolithic system becomes easier to split into a set of micro-services or processes. From the talk, attendees will learn several practical tips and tricks on how to split component containers into smaller ones
