Spring Boot – It is an enterprise-level framework and an open source that helps to create production-grade applications that run on JVM (Java Virtual Machine). It is also a tool, which makes developing microservices and web applications with spring framework simpler and faster via three core abilities such as

1. The capability to make standalone applications
2. Autoconfiguration
3. An opinionated approach or method to configuration

These best features work together and provide with a tool, which allows users to set up a spring-based application with minimal configuration.

Microservices – It is an architectural pattern, which arranges an application as a collection of fine-grained and loosely coupled services and communicates via lightweight protocols. The main aim of microservice is that teams may deploy and develop their services independently of others and this is achieved by reducing many dependencies in the code base. It also enables developers to evolve their several services by limiting restrictions on users. The microservice structure allows a company to deliver large or complex applications rapidly, sustainably, and reliably.

Building Microservices with Spring Boot – In recent years, Microservices architecture has become enhancing popular among developers worldwide This type of architectural style also includes breaking down an application into smaller and independent services which may be deployed and developed separately. Spring Boot is also one of the popular frameworks for building microservices in Java. There are several steps that are involved in making or building microservices with the help of Spring Boot are given below –

1.  Set up a development environment – Firstly, it is important to set up your development environment and ensure that you have Java and the latest version of Spring Boot installed. You can also use an IDE (Integrated Development Environment (IDE) such as IntelliJ or Eclipse to make the development procedure simpler.
2.  Define Microservices architecture – It is also essential to define your microservices architecture before starting coding. You may also use several tools OpenAI or Swagger for defining your RESTful APIs and make sure that they adhere to best practices.
3. Make your Microservices – When you have defined your microservices architecture then you may start making or creating your microservices. You can also start by making a new Spring Boot project for each microservice. Each microservice must have its own database and may use Spring Data JPA (Java Persistence API) to make and manage database entities.
4. Define API Endpoints – It is important to define your API endpoints and use Spring MVC to make or create RESTful endpoints for each microservice. In this step, you can also use several tools such as Rest or Feign Template to create HTTP calls between microservices.
5. Implement Business Logic – Now, you can start implementing your business logic after defining your API endpoints. In this step, you can use Spring Framework’s Dependency Injection feature to inject dependencies into the code. You can also use the feature of Spring Boot’s autoconfiguration to configure or arrange your application which is based on best practices.
6. Test your Microservices – After implementing your business logic, you can test your microservices. To test your microservices, you can use several tools such as JUnit and Mockito to write unit tests for each microservice. You can also use many tools such as Postman to test your APIs.
7. Deploy your Microservices – It is the best time to deploy your microservices to your preferred deployment environment after testing your microservices in the last step. To deploy your microservices, you can use tools such as Kubernetes and Docker for creating containerized deployments. You can also use CI/CD tools such as Jenkins or Travis CI to automate your deployment procedure.

Conclusions – In this blog, you can read several steps about building microservices with the help of Spring Boot. Every step is important to build a reliable and scalable microservices application. You can build microservices, which may be developed and deployed separately that makes your development procedure more productive and efficient by using the new technologies and tools and following best practices.
