Building Microservices with Spring

By: Dinesh Rajput, Rajesh R V

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

Implementing security


It is important to secure the microservices. This will be more significant when there are many microservices communicating with each other. Each service needs to be secured, but at the same time, security shouldn't surface as an overhead. In this section, we will learn some basic measures to secure microservices.

Note

The full source code of this example is available as the chapter3.security project in the code files of this book under the following Git repository:https://github.com/rajeshrv/Spring5Microservice

Perform the following steps for building this example:

  • Create a new Spring Starter project, and select Web and Security (under core)
  • Name the project as chapter3.security
  • Copy rest endpoint from chapter3.bootrest

Securing a microservice with basic security

Adding basic authentication to Spring Boot is pretty simple. The pom.xml file will have the following dependency. This will include the necessary Spring security library files:

    <dependency>
