Java EE: Logging User Interaction the Aspect-Oriented Way using Interceptors

Mon, 26 May 2014 00:00:00 +0200

Using dependency injection and aspect-oriented mechanisms like interceptors allow us to separate cross-cutting-concerns in our Java enterprise application, to control global aspects of our application and to avoid boilerplate code.

In the following short tutorial we’re going to create an aspect-oriented logger to protocol the initiating user, class and method called and the parameters passed to the method and finally we’re adding this interceptor to a sample RESTful web-service by adding a simple annotation.

Java EE 6, GlassFish and the Interceptor API

Wed, 17 Aug 2011 00:00:00 +0200

Aspect oriented programming and the definition of cross-cutting-concerns is made easy in Java EE 6 using interceptors.

In the following tutorial we’re going to take a look at the different possibilities to apply interceptors to your EJBs at class or method level and how to setup a GlassFish instance to run the examples.

Prerequisites

We don’t need much for the following tutorial – just a JDK, Maven and GlassFish…

Spring 3, Maven and Annotation Based Configuration

Sun, 22 Aug 2010 00:00:00 +0200

There is still the urban myth that using Spring IoC container without thousands lines of XML code isn’t possible – so today we’re taking a look at annotation based configuration with Spring 3 and of course we’re using Maven..

Setup your project

Create a simple Maven project using

mvn archetype:generate // or
mvn archetype:create

Add a lot of dependencies and reference them to the Spring version defined as a property in your pom.xml. A good reference on Spring 3 and Maven artifacts can be found at Springsource.com
