Spring Book - Chapter 8 - Data Access

One of the very important aspect in any enterprise application is the ability to get data in and out of your application with ease. Thinking on the same lines, Spring framework provides extensive support for data access. In this Chapter we will first explore the various data access technologies and then see the support provided by Spring for using these technologies in your application.

Spring effectively makes data access easier by managing the various resource for you, by providing abstraction and easy API helpers and by supporting all major data access technologies available in the industry so that you don’t have to get yourself bogged down to a particular technology. Going along with the Spring philosophy it lets your Spring application integrate to any data access technology with ease.

In this Chapter we will see the support given the Spring framework in interacting between data access layer and the service layer in your application. Spring compressive support for transaction management will be covered briefly as we have dedicated Chapter 9 for this specific topic. In this chapter we will also be covering various data access frameworks and technologies which the Spring framework integrates with almost ease.

Chapter 8: Data Access

Spring Book - Chapter 7 - Testing

Testing is an integral part of enterprise software development. It is one of the most important phases of the Software Development Lifecycle (SDLC) and has gained more importance in last decade or so. Having said that, there are many constraints either from framework level or project level, which makes testing effort in a project more challenging and time consuming. In this chapter we will first touch upon the importance of testing and see what are the various testing techniques employed in a typical application. Along the way we will see the problems imposed by various frameworks in achieving full test coverage.

After that we will see, how the Spring framework supports you in making your application more testable.

Spring Book - Chapter 6 - Enterprise Integration

Spring’s core support includes its capability of configuring application, enterprise integration, its testing capabilities and data access methodologies. In Chapter 4, I introduced you to various configuration styles available in Spring. In Chapter 5, I continued on to explain the various simplifications that you can do in your application. In this Chapter I will be covering enterprise integration which is one of the core support provided by the spring framework in detail.

I always like to call an application enterprise. For an application to be called enterprise, it needs to have enterprise components/objects on which it is built. I call an object enterprise when it has capability to handle transactions, capable of existing in a secured environment, has capability to integrate with other system, and so forth.

Using Spring framework, you can make simple POJOs getting transformed into what I call as enterprise objects, with minimal involvement of developers. Developers spend more time writing the actual business logic and the Spring container does all the magic behind the scenes.

Spring framework provides comprehensive infrastructural support for what we call an enterprise application. One such important component in any enterprise application is its capability to integrate. Spring handles plumbing involved in integrating various components in an enterprise application so that you can focus on actual business logic/business use case. Integrating enterprise application can be done in many ways. Each way has its own advantages and disadvantages. We will be discussing the various enterprise integration styles available in some detail in subsequent sections and will also cover the support rendered by Spring to achieve these integration styles in your enterprise application.

Chapter 3: Spring Quick Start

Spring Book - Part II - Core Support by Spring

Any enterprise application is typically made of multiple components working in tandem to realize a business case. Usually the objects communicate with each other in some form to achieve this in an application. Achieving component interaction can be cumbersome and difficult to implement in any application. Even if it is considered easy to do, it might become very hard to replace a component with other component due to challenging business scenarios. Spring Framework does this sort of component interaction which can be seamlessly changed with changing scenarios efficiently and easily.

Spring Book - Chapter 2 - Getting started with Spring

Developing enterprise application using Spring Framework is much simpler than using standard Java EE in many ways. Even though Java EE’s declarative programming model using EJB simplifies infrastructural aspects of development such as transactions and security, t still introduces unwanted complexity to the application as a whole. Developers need to still write more Framework code than the application code. Over the period Java EE has also redefined itself to introduce new programming techniques like Aspect Oriented Programming (AOP) and Dependency Injection (DI). So many new Frameworks got evolved using these techniques. Leading from this pack of Framework at the moment is by Spring Framework by a long way. In this chapter I will try to give you details on various aspects of Spring Framework, along with the sample application that will be used throughout this book to show the various concepts in this Framework.

In this chapter, I will give you details on how you can start building applications with Spring Framework. I will also give details on the sample application on which the entire book is based. It also talks about the some basic concepts which are very much essential for understanding Spring in a holistic way.

Chapter 2: Getting Started With Spring

Spring Book - Chapter 1 - Introduction

Over the last few years, Spring has grown substantially, surpassing many other frameworks. Spring enables you to concentrate on writing less Spring-Framework-related code and more application code, which is vital in the fast-changing and cost-sensitive world of enterprise applications. Since its initial release in 2004, Spring has reinvented itself multiple times and become prominent in the industry as a strong force in the framework market. This has not only made the Spring Framework renowned, but it has also put healthy pressure or rather competition on well-known industry specifications (Java EE) and the application-server market. In the Java world, this is a very exciting time and a very important turning point.

In this chapter, I introduce Spring Framework as a whole (If I could, I would compel you to use it). Before explaining the nitty-gritty, I give you reasons to choose Spring for your application. Then I explain the Spring framework architecture and its features and, more important, introduce you to the main modules on which Spring Framework is based.

Chapter 1: Introduction

Spring Book - Part 1 - Overview

Spring Framework is a Java platform that provides all-inclusive infrastructure support for developing JEE applications. It handles the almost all the plumbing/boilerplate code required for your application so that you can focus on your business specific logic while building your enterprise application. Simple Plain Old Java Objects (POJOs) becomes powerful objects having middleware services like security, transaction management etc. inside the Spring Container. Part 1 introduces you to the Spring Framework and also tries to introduce various core concepts on which Spring Framework is built on.

In Chapter 1, “Introduction”, you will get to know overview, history, overall architecture, building blocks, and features of the spring framework in detail.

In Chapter 2, “Getting Started with Spring Framework”, I will show you how to get set up for building applications with Spring Framework, and I will introduce the sample application on which the book is based. Chapter 2 also introduces some basic concepts that are essential for understanding Spring in a holistic way.

So here we go, I hope you will enjoy reading this book as much as I did in writing it for you.
