In this article we will see how to configure and integrate SpringMVC4, Spring Data JPA with Hibernate and SpringSecurity using JavaConfig.

1. Pom.xml

First let’s configure all the necessary dependencies in pom.xml

ORM has a simple, production-ready solution hiding in plain sight in the Java world. Let’s go through it in this post, alongside with the following topics:

• ORM / Hibernate in 2014 – the word on the street
• ORM is still the Vietnam of Computer Science
• ORM has 2 main goals only
• When does ORM make sense?
• A simple solution for the ORM problem
• A production-ready ORM Java-based alternative

Jetty 9.1 is finally released, bringing Java WebSockets (JSR-356) to non-EE environments. It’s awesome news and today’s post will be about using this great new API along with Spring Framework.

JSR-356 defines concise, annotation-based model to allow modern Java web applications easily create bidirectional communication channels using WebSockets API. It covers not only server-side, but client-side as well, making this API really simple to use everywhere.

In some of my recent work I got the request to produce a custom Reason Phrase in the  HTTP status response delivered to one of our REST API consuming clients when an error occurs. In this post I will demonstrate how you can achieve that with Jersey.

Introduction

An incremental software development process requires an incremental database migration strategy.

I remember working on an enterprise application where the hibernate.hbm2ddl.auto was the default data migration tool.

Updating the production environment required intensive preparation and the migration scripts were only created on-the-spot. An unforeseen error could have led production data corruption.
