Building Microservices with Spring

Overview of this book

Getting Started with Spring Microservices begins with an overview of the Spring Framework 5.0, its design patterns, and its guidelines that enable you to implement responsive microservices at scale. You will learn how to use GoF patterns in application design. You will understand the dependency injection pattern, which is the main principle behind the decoupling process of the Spring Framework and makes it easier to manage your code. Then, you will learn how to use proxy patterns in aspect-oriented programming and remoting. Moving on, you will understand the JDBC template patterns and their use in abstracting database access. After understanding the basics, you will move on to more advanced topics, such as reactive streams and concurrency. Written to the latest specifications of Spring that focuses on Reactive Programming, the Learning Path teaches you how to build modern, internet-scale Java applications in no time. Next, you will understand how Spring Boot is used to deploying serverless autonomous services by removing the need to have a heavyweight application server. You’ll also explore ways to deploy your microservices to Docker and managing them with Mesos. By the end of this Learning Path, you will have the clarity and confidence for implementing microservices using Spring Framework. This Learning Path includes content from the following Packt products: • Spring 5 Microservices by Rajesh R V • Spring 5 Design Patterns by Dinesh Rajput

Common GoF Design Pattern overview


The authors Erich Gamma, Richard Helm, Ralph Johnson, and John Vlissides are often referred to as the GoF, or Gang of Four. They published a book titled Design Patterns: Elements of Reusable Object-Oriented Software, which initiated the concept of design patterns in software development.

In this chapter, you will learn what GOF patterns are and how they help solve common problems encountered in object-oriented design.

The Gang of Four (GoF) patterns are 23 classic software design patterns providing recurring solutions to common problems in software design. The patterns are defined in the book Design Patterns: Elements of Reusable Object-Oriented Software. These patterns are categorized into two main categories:

  • Core Design Patterns
  • J2EE Design Patterns

Furthermore, Core Design Patterns are also subdivided into three main categories of design pattern, as follows:

  • Creational Design Pattern: Patterns under this category provide a way to construct objects when constructors...
