Dependency injection - Dhanji R. Prasanna

HIGHLIGHT

The ?Dependency Injection? (DI) pattern is the primary idea behind the enormously

popular Spring Framework and Google Guice. This book shows Java

developers how to effectively use DI in multiple frameworks and contexts and

presents the most current technologies, techniques and best practices.

Dependency Injection is an in-depth guide to the current best practices for

using the Dependency Injection pattern?the key concept in Spring and the

rapidly-growing Google Guice. It explores Dependency Injection, sometimes

called Inversion of Control, in fine detail with numerous practical examples.

Developers will learn to apply important techniques, focusing on their strengths

and limitations, with a particular emphasis on pitfalls, corner-cases, and best

practices.

This book is written for developers and architects who want to understand

Dependency Injection and successfully leverage popular DI technologies such as

Spring, Google Guice, PicoContainer, and many others. The book explores

many small examples of anchor concepts and unfolds a larger example to show

the big picture.

Written primarily from a Java point-of-view, this book is appropriate for any

developer with a working knowledge of object-oriented programming in Java,

Ruby, or C#.

? Both highly technical and highly practical

? Numerous examples in multiple languages, frameworks, and contexts

? The only book available that covers DI from a framework-agnostic perspective;

most concentrate only on Spring.

Dependency Injection is one of the most important ideas of the past decade for

object-oriented developers, but it isn?t widely understood at a technical level. DI

has increased in importance as developers have embraced the Agile ideas of

building testable and maintainable code. All Java developers need to master the

DI concepts in this book.
