Scars from the Journey: Crafting Clean & Effective Java EE applications with DDD

Hands-on Labs

ssj Server Side Java

Ever seen Service classes with hundreds or maybe thousands of LOC cluttered with validation logic, DAO access and some business code? Tired of getting NullPointerExceptions and having to check everything with if != null? Filled up of recurring bugs that could be prevented by unit tests, but your code is simply too clumsy to test effectively? Then you definitely should check this session.

We'll show how Domain-Driven Design, proper encapsulation, immutability, Value Objects, Entities and Aggregates, Repositories and Specifications can help you solve all of these problems. Already knew these concepts but never figured out how to proper apply them in production code? We have these answers with a lot of tips & tricks from the real world. Don't miss this 100% live code where we'll craft an application from the database to the view using Domain-Driven Design, Clean Code and Effective Java on top of Java 8 and Java EE 7. You'll never see your code the same way again.
