Implementing lambda expressions using anonymous inner classes

The implementation of functional programming principles in Java has started with the use of anonymous inner classes. Starting with Java 1.7, an abstract method of a certain interface now can be implemented using anonymous inner classes, and even without using the implements keyword, given that it has only one abstract method.

Getting started

Create an Eclipse Maven project, ch06, and pattern the Maven configurations from the previous chapter's pom.xml. Copy the previous SpringContextConfig, SpringDbConfig, SpringDispatcherConfig, and SpringWebinitializer and place them inside their new respective packages under the org.packt.functional.codes core package. Update the DispatcherServlet configuration details and all the copied context definition classes to set up the new project. Reuse also the Employee model and DAO classes used previously.

How to do it...

Functional programming in Java can be illustrated by an interface with one abstract...

Building RESTful Web Services with Spring 5

Building RESTful Web Services with Spring 5

REST is an architectural style that tackles the challenges of building scalable web services. In today's connected world, APIs have taken a central role on the web. APIs provide the fabric through which systems interact, and REST has become synonymous with APIs.The depth, breadth, and ease of use of Spring makes it one of the most attractive frameworks in the Java ecosystem. Marrying the two technologies is therefore a very natural choice.This book takes you through the design of RESTful web services and leverages the Spring Framework to implement these services.
