Spring Recipes: A Problem-Solution Approach

Posted by karldmoore on February 17, 2009

springrecipesI recently had the pleasure of reading Spring Recipes: A Problem-Solution Approach. I first began reading the sample chapters released on the authors website, so when the book was finally finished I was really looking forward to getting hold of a copy. When it arrived I was amazed to see that it weighed in at a hefty 752 pages, but that really shouldn’t put you off.

Spring Recipes covers Spring 2.5 (and earlier versions) taking it from the simplest concepts right through to the most advanced level. The book is divided into nineteen chapters organised into three parts; Core, Fundamentals and Advanced. Each part builds on the previous ones to grow your understanding of all aspects of the Spring framework, for this reason the book is best read cover to cover.

This book is in no way filler and is packed full of content covering not only the Spring framework and but also several common Spring projects including; Spring Security, Spring Web Flow and Spring Web Services. For anyone that knows Spring (and it’s associated projects), this is a huge amount of information to cover in just one book, but this book really does deliver!

As the author puts it; “Reading Spring Recipes will help you master the most important 80 percent of Spring’s features with just 20 percent of the effort you would need to learn them all.” If you are already using Spring, this book will serve as an invaluable reference and companion guide for future development. If you are a newcomer to Spring, this book will serve as an excellent launch pad to get you up, running and productive with Spring very quickly.


Each of the recipes covered in the book follows; a problem, solution and then how it works approach. This approach lays out many of the common FAQ style questions that come up on Spring Forum in an accessible way; clearly outlining the problem and mapping the path to the solution. This book also acts an excellent companion to the Spring Reference manual, which is sometimes difficult to read in places and lacks the array of examples this book provides.


The intended audience for Spring Recipes, is any Java programmer hoping to learn more about Spring. No prior knowledge of Spring is required as this book covers it all right from core concepts such as inversion of control (or Ioc). This book is accessible to anyone who has heard the hype about Spring and simply wants to learn more about it and how they can leverage it’s power. This book gives Java developers hands-on experience using the Spring framework with real-world examples, this experience can be transferred straight into your Spring project.


Part 1: Core

This part focuses on the core concepts and mechanisms of the Spring framework. The chapters in this part aim to familiarize you with Spring’s core. As a newcomer to Spring Chapter 1 introduces the concept of inversion of control the core foundation of Spring. It explains how and IoC container works, but also why it is useful and beneficial to use one. This chapter serves as an excellent introduction to IoC and is invaluable to anyone who isn’t quite sure why they should use a container based approach. This chapter is a must for anyone new to Spring or anyone trying to deliver it to a new audience.

Chapters 2-4 build on the IoC introduction, explaining how to setup and configure a new Spring project and apply the basics of Spring configuration. These first four chapters are the foundation for the rest of the book and are a must read for anyone who has never used Spring before and even advanced users may find useful hints and tips within. Chapters 5-6 cover the extremely powerful approach of AOP, introducing crosscutting concerns and how these can be configured with Spring. This technique can be extremely useful to provide trace logging, caching and other crosscutting concerns such as security. This is a must read for anyone using Spring, even if you are not directly leveraging Spring AOP or AspectJ. Spring AOP lays the foundation for introducing how Spring provides features such as transparent transaction support and method level authorization checking.

Part 2 : Fundamentals

This part has a split focus, it introduces Spring’s Data Access support, Web integration and also Testing support. Chapter 7 introduces one of the most important aspects of Spring’s data access support in the form of JdbcTemplate. This shows the reader how they can use JdbcTemplate to prevent the use of direct JDBC and instead let Spring handle all of the boiler plate code. As JdbcTemplate removes the need for the common try/catch/finally/try/catch code seen with JDBC, the code is much cleaner and much more readable. Along with this support, the Spring DataAccessException hierarchy is introduced which provides a rich set of common exceptions to provide a more granular handling approach.

Chapter 8 introduces Spring’s excellent transaction management support and explains in great detail all of the various propagation behaviours and isolation levels. This chapter is one of my favourites as it not only introduces the concept of Spring transaction support but transactions in general. It’s accessible to everyone and extremely useful when mentoring new developers.

Chapter 9 discusses how to integrate Spring with existing ORM frameworks, making their usage within the application seamless. This provides multiple approaches to integration allowing you to build on existing Spring classes, or completely decouple your classes from Spring removing the need for any Spring imports within your code. Chapters 10-11 discuss Spring’s popular MVC framework and also discuss how many other leading web frameworks can be integrated with a Spring application. As many of the projects I have worked on in the past have used Struts, Chapter 11 was particularly useful to outline all of the options available to use Spring and Struts together.

This part finishes with the introduction of Spring Testing Support, teaching you not only what features Spring has to offer but also how it integrates with popular testing frameworks such as JUnit and TestNG. As the Spring Testing support has been overhauled, it was great that this book covered the TestContextframework, but also legacy test classes to cover older versions of JUnit and TestNG. This chapter helps you leverage not only IoC for your tests but also transaction support, mock testing and also MVC integration testing. This approach enables you to easily decouple your code from your tests, providing first class support for all your testing needs.

Part 3 : Advanced

For anyone that has mastered the first twelve chapters, Chapter 13 is where things start to get really interesting. This chapter is dedicated to one of the most scary Spring projects, namely Spring Security (formerly known as Acegi). Spring Security provides a full range of authentication, authorization and access control options which allow it to secure a standalone Java application or a web-based application. This book focuses on version 2.x onwards which dramatically reduced the size of the required configuration and also its complexity. Spring Security can be a difficult subject to tackle as it’s often hard for developers to understand it’s concepts, but this chapter builds security into the example application in piecemeal steps. This demystifies many of the problematic areas of Spring Security whilst addressing the common problems a new developer might face.

Chapter 14 covers the portlet application development using the Spring Portlet MVC framework, highlighting the portlet-specific features which differ from the standard Spring MVC framework. If you don’t require the portlet features currently within your application, this chapter can safely be skipped as the next one is another gem. Chapter 15 covers the Spring Web Flow framework which addresses the three major pain–points facing web application developers: user interface navigation control, state management, and modularity. Spring Web Flow offers a flow definition language which encapsulates a reusable sequence of steps that can execute in different contexts. This framework is extremely flexible and powerful, but this chapter provides a great introduction into what is a very large subject.

Chapter 16 introduces the remoting integration that Spring provides for various technologies such as RMI, Hessian, Burlap, HTTP Invoker, and Web Services. Having already been familiar with many of these technologies, this chapter provides an excellent insight into how these can be integrated with Spring and how quickly this can be achieved. This chapter concludes with a look at Spring Web Services including how to develop contract-first web services. Chapter 17 discusses how to develop EJB 2.x and 3.0 components with Spring’s EJB support, and how to use Spring’s JMS support to simplify sending, receiving, and listening to JMS messages. This introduces a powerful concept of message-driven POJOsfor those who like the concept of message-driven beans (MDBs) but don’t want the restrictions of an EJB container.

Chapter 18 demonstrates how easily Spring beans can be exported as JMX MBeans with relative ease in comparison to the typical approach. It continues to extend this by providing remote access, auto-detection and notification. This chapter continues by introducing Spring’s email support which removes the reliance on JavaMail specific mail sessions and exceptions. This provides an abstraction which is independent making it easy to switch to another e-mail API. This chapter finishes with a look at the options available for scheduling tasks within the Spring framework, this integrates with the JDK Timer and also Quartz scheduler.

Chapter 19, this part and the book concludes with a look at the various scripting languages that can used with Spring applications including; JRuby, Groovy and BeanShell. One of the most powerful features of using scripts is that any changes made to these can be detected by Spring and thus the beans can be refreshed automatically. This is of great benefit when you wish to avoid the long compile, deploy and test cycles or the application cannot be taken down regularly for maintenance. This chapter demonstrates how scripted beans can be added to your application quickly and simply using Spring.


This book has undertaken a mammoth task, trying to squeeze Spring and associated projects all into one book. This book is very clearly written, with well-structured, concise examples that get to the heart of the problem without complicating it with unnecessary detail. The examples provide solutions to real world problems instead of taking the form of the simplistic examples found in many other technology books. My only real minor criticism of this book is it’s scope and size. Given the huge undertaking, there are obviously going to be some areas which only provide a minimal amount of information. This should be expected given the vast array of information covered, but there are a range of Apress books which can build on this foundation. I would still give this book five out of five and rate it as one of the best framework specific books I’ve read.

This book should accompany anyone starting their journey with the Spring framework and even seasoned developers. It can take you from knowing nothing about the Spring framework to knowing pretty much everything you need to create a fully functional web application with all the bells and whistles you’d expect. It provides information and examples on numerous integration points with other popular open source frameworks and languages allowing you to truly become a Spring expert. Read it, read it again and keep it on your bookshelf as a solid reference for the Spring framework.

Working with Spring Web Flow book is released

Posted by karldmoore on September 5, 2007

I’ve just been informed that Working with Spring Web Flow has been released. It will be the first Spring Web Flow book from the father and co-lead of the framework Erwin Vervaet. If that isn’t official enough, Keith Donald the co-lead of Spring Web Flow and lead of the Web Application Development Products Team for Interface21 is one of the technical reviewers. It really is ‘Spring from Source’.

For those of you who haven’t had the pleasure of working with Spring Web Flow and don’t know what it is, the home page describes it as:

“a next generation Java web application controller framework that allows developers to model user actions as high-level modules called flows. The framework delivers improved productivity and testability while providing a strong solution to enforcing navigation rules and managing application state.”

Spring Web Flow boasts a very active user forum and also an excellent portal containing tips, tricks, and a practical introduction into Spring Web Flow. Working with Spring Web Flow provides an excellent companion to these resources, not only teaching you how to work with Spring Web Flow, but also helping you understand the rationale and motivation behind the framework. To quote the author:

This book aims to teach you how to work with Spring Web Flow. It will cover both basic and advanced use-cases, and provides an in-depth reference to all of the features Spring Web Flow currently offers. You’ll learn how to extend the framework and take it beyond its out of the box feature set. Once you’ve finished this book you’ll be able to call yourself a Spring Web Flow expert!

This book is intended to be a reference for both new and advanced Spring Web Flow users. If you’re a new user, you’ll learn how to get started using Spring Web Flow and leverage all of its powerful features. As an advanced user you’ll learn how to extend the framework and many of its best practices. Advanced users will also find this book provides very interesting insights into the design of Spring Web Flow.

I have already had the pleasure of reading the book, as Erwin very kindly invited me to be the second technical reviewer. Although I’d heard of Spring Web Flow before Erwin approached me, I hadn’t had chance to learn much about it. I found this book an excellent jump-start into the world of Spring Web Flow and it’s now an invaluable reference manual!

I know how hard Erwin has been working on this book and I’m really looking forward to seeing the finished product! Reviewing it has been a really great experience and I’d love to do this again in the future. I’m really grateful to Erwin for the opportunity and hope lots of people buy the book!
