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

About Packt


After reading this chapter, you should now have a good idea about DI design patterns, and the best practices for applying those patterns. Spring deals with the plumbing part, so, you can focus on solving the domain problem by using the dependency injection pattern. The DI pattern frees the object of the burden of resolving its dependencies. Your object is handed everything that it needs to work. The DI pattern simplifies your code, improves code reusability, and testability. It promotes programming to interfaces, and conceals the implementation details of dependencies. The DI pattern allows for centralized control over the object's life cycle. You can configure DI via two ways--explicit configuration and implicit configuration. Explicit configuration can be configured through XML-or Java-based configuration; it provides centralized configuration. But implicit configuration is based on annotations. Spring provides stereotype annotations for Annotation-based configuration. This configuration...
