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

Spring Boot actuators for microservices instrumentation


The previous sections explored most of the Spring Boot features required for developing a microservices. In this section, we will explore some of the production-ready operational aspects of Spring Boot.

Spring Boot actuators provide an excellent out-of-the-box mechanism for monitoring and managing Spring Boot microservices in production.

Note

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

Create another Spring starter project, and name it as chapter3.bootactuator.application; this time, select the Web, HAL browser, hateoas, and Actuator dependencies. Similar to chapter3.bootrest , add a GreeterController endpoint with the greet method. Add management.security.enabled=falseto the application.properties file to grant access to all endpoints.

Do the following to execute the application:

  1. Start...
