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

Chapter 3. Wiring Beans using the Dependency Injection Pattern

In the previous chapter, you learned about the Gang of Four (GOF) design patterns with examples and use cases of each. Now, we will go into more detail about injecting beans and the configuration of dependencies in a Spring application, where you will see the various ways of configuring in a Spring application. This includes configuration with XML, Annotation, Java, and Mix.

Everyone loves movies, right? Well, if not movies, how about plays, or dramas, or theatre? Ever wondered what would happen if the different team members didn't speak to each other? By team I don't just mean the actors, but the sets team, make-up personnel, audio-visual guys, sound system guys, and so on. It is needless to say that every member has an important contribution towards the end product, and an immense amount of coordination is required between these teams.

A blockbuster movie is a product of hundreds of people working together toward a common goal...
