Maven will automatically resolve the other dependencies. Here, we specify the dependencies for the Spring Boot, Spring Boot JPA, and MySQL connector. Now, open the eclipse ide and let us see how to implement this tutorial in the spring boot module using the jpa-starter library to communicate with a relational database.

It provides a powerful batch processing and manages the rest endpoints.

It helps in removing the boilerplate code, extra annotations, and xml configurations.

It automatically identifies the required dependencies and imports them in the application

It simplifies the maven configuration by providing the starter template and helps to resolve the dependency conflicts.

It creates applications that are packaged as jar and are directly started using embedded servlet container (such as Tomcat, Jetty or Undertow).

Spring Boot is a module that provides rapid application development feature to the spring framework including auto-configuration, standalone-code, and production-ready code.

Welcome readers, in this tutorial, we will explore the crud operations in spring boot module of the spring framework.
