It’s pretty common to find yourself working with generics in Scala, but you may find yourself where you want a generic with some constraints. Generally, these constraints can be boiled down to “Subclass” or “Superclass” and Scala offers functionality out of the box to help facilitate this.

Creating a Java Bean from a Scala Class

Sometimes, you may find yourself in a situation (like using Scala with Spring) where you need to generate a Java bean but would like to do that in Scala. By default, Scala classes don’t adhere to the requirements of the Bean definition, namely autogenerating getters and setters. Thankfully, there is a BeanProperty decorator that can […]
