Spring AOP Tutorial

What is Spring AOP?

One of the key components of Spring Framework is the Aspect Oriented Programming (AOP) framework. Aspect Oriented Programming entails breaking down program logic into distinct parts called so-called concerns. This tutorial will take you through simple and practical approaches while learning AOP framework provided by Spring.

This Spring AOP tutorial is based on the latest Spring 7.0.0-M9 version.

Applications of Spring

Following is the list of few of the great benefits of using Spring Framework −

• POJO Based - Spring enables developers to develop enterprise-class applications using POJOs. The benefit of using only POJOs is that you do not need an EJB container product such as an application server but you have the option of using only a robust servlet container such as Tomcat or some commercial product.

• Modular - Spring is organized in a modular fashion. Even though the number of packages and classes are substantial, you have to worry only about the ones you need and ignore the rest.

• Integration with existing frameworks - Spring does not reinvent the wheel, instead it truly makes use of some of the existing technologies like several ORM frameworks, logging frameworks, JEE, Quartz and JDK timers, and other view technologies.

• Testablity - Testing an application written with Spring is simple because environment-dependent code is moved into this framework. Furthermore, by using JavaBeanstyle POJOs, it becomes easier to use dependency injection for injecting test data.

• Web MVC - Spring's web framework is a well-designed web MVC framework, which provides a great alternative to web frameworks such as Struts or other over-engineered or less popular web frameworks.

• Central Exception Handling - Spring provides a convenient API to translate technology-specific exceptions (thrown by JDBC, Hibernate, or JDO, for example) into consistent, unchecked exceptions.

• Lightweight - Lightweight IoC containers tend to be lightweight, especially when compared to EJB containers, for example. This is beneficial for developing and deploying applications on computers with limited memory and CPU resources.

• Transaction management - Spring provides a consistent transaction management interface that can scale down to a local transaction (using a single database, for example) and scale up to global transactions (using JTA, for example).

Who Should Learn Spring AOP?

Spring AOP module lets interceptors intercept an application. For example, when a method is executed, you can add extra functionality before or after the method execution. This tutorial is tailored for readers who aim to understand and utilize Spring AOP for development using Java programming language. In this tutorial, we'll cover all the ways of using Spring AOP which helps in solving the common problems developers/users face during java based development.

Prerequisites to Learn Spring AOP?

To maximize the benefits of this tutorial, readers should have a basic understanding of Java programming. Knowledge of I/O Operations, File handling will enhance comprehension. A basic understanding of Eclipse IDE is also required because all the examples have been compiled using Eclipse IDE.
