Mastering Spring Boot 2.0

By: Dinesh Rajput

Overview of this book

Spring is one of the best frameworks on the market for developing web, enterprise, and cloud ready software. Spring Boot simplifies the building of complex software dramatically by reducing the amount of boilerplate code, and by providing production-ready features and a simple deployment model. This book will address the challenges related to power that come with Spring Boot's great configurability and flexibility. You will understand how Spring Boot configuration works under the hood, how to overwrite default configurations, and how to use advanced techniques to prepare Spring Boot applications to work in production. This book will also introduce readers to a relatively new topic in the Spring ecosystem – cloud native patterns, reactive programming, and applications. Get up to speed with microservices with Spring Boot and Spring Cloud. Each chapter aims to solve a specific problem or teach you a useful skillset. By the end of this book, you will be proficient in building and deploying your Spring Boot application.

Configuring the Spring Cloud application


One of the major issues of the cloud-native application is maintaining and distributing configuration across the distributed services; developers spend lot of time configuring each environment-specific configuration. But at the time of scaling our service horizontally, we have to again reconfigure our services. Spring Cloud provides a module or sub-project for this cloud-native problem. This module is known as a Spring Cloud Config.

Spring Cloud Config is a sub-project of the Spring Cloud ecosystem. It provides a server and client approach to store and sever distributed configurations across several environments and distributed systems.

External configuration management is centralized and upheld by a Git repository. The configuration assets delineate to the Spring environment, but could be utilized by non-Spring applications if we wanted. We can create an external configuration and we can use the existing configuration on the central place, such Git...
