What this book covers

Chapter 1, Getting Started with the Spring Framework 5.0 and Design Patterns, gives an overview of the Spring 5 Framework and all new features of the Spring 5 Framework, including some basic examples of DI and AOP. You’ll also get an overview of the great Spring portfolio.

Chapter 2, Overview of GOF Design Patterns - Core Design Patterns, gives an overview of the Core Design Pattern of the GoF Design Patterns family, including some best practices for an application design. You'll also get an overview of the common problems solving with design patterns.

Chapter 3, Consideration of the Structural and the Behavioural Patterns, gives an overview of the Structural and Behavioural Design Pattern of the GoF Design Patterns family, including some best practices for an application design. You’ll also get an overview of the common problem solving with design patterns.

Chapter 4, Wiring Beans using Dependency Injection Pattern, explores dependency injection pattern and detail about the configuration of Spring in an application, showing you various ways of configurations in your application. This includes a configuration with XML, Annotation, Java, and Mix.

Chapter 5, Understanding the Bean Life cycle and Used Patterns, gives an overview of Spring Bean Life cycle managed by the Spring container, including an understanding of Spring containers and IoC. You'll also get an overview of the Spring bean life cycle callback handlers and post processors.

Chapter 6, Spring Aspect Oriented Programming with Proxy and Decorator Pattern, explores how to use Spring AOP to decouple cross-cutting concerns from the objects that they service. This chapter also sets the stage for later chapters where you'll use AOP to provide declarative services such as transactions, security, and caching.

Chapter 7, Accessing Database with Spring and JDBC Template Pattern, explores how to access the data with Spring and JDBC; here, you’ll see how to use Spring's JDBC abstraction and JDBC Template to query relational databases in a way that is far simpler than native JDBC.

Chapter 8, Accessing Database with Spring ORM and Transactions Implementing Patterns, shows how Spring integrates with the ORM Frameworks, such as Hibernate and other implementations of the Java Persistence API (JPA) with Spring Transaction Management. Also, this contains magic provided by Spring Data JPA for on-the-fly queries generation.

Chapter 9, Improving Performance of Application using Caching Patterns, shows how to improve application performance by avoiding the database altogether if the data needed is readily available. So, I will show you how Spring provides support for caching data.

Chapter 10, Implementing MVC Pattern in a Web Application using Spring, gives a quick overview of developing a web application with the Spring MVC. You'll learn the MVC pattern, Front Controller pattern, Dispatcher Servlet with the basics of Spring MVC, a web framework built on the principles of the Spring Framework. You'll discover how to write controllers to handle web requests and see how to transparently bind request parameters and payload to your business objects while providing validation and error handling at the same time. This chapter also gives a brief introduction to view and view resolver in the Spring MVC.

Chapter 11, Implementing Reactive Design Pattern, explores the Reactive Programming Model, which is programming with asynchronous data streams. You'll see how the Reactive System is implemented in the Spring Web Module.

Chapter 12, Implementing Concurrency Patterns, takes a closer look at concurrency when handling multiple connections inside a web server. As outlined in our architectural model, request handling is decoupled from application logic.
