In the previous Spring Boot JdbcTemplate Tutorial we have seen how to initialize database using schema.sql and data.sql scripts. This may be useful for demos and quick prototypes, but for real world applications we should use a database migration tool.

Spring provides a high-level abstraction on top of JDBC with JdbcTemplate to make it easier to perform database operations. Spring also provides a high-level abstraction on top of JPA with Spring Data JPA to make it easy to implement CRUD operations, sorting, pagination, etc.

Introducing Spring Boot JDBC Support

Spring’s JdbcTemplate provides high-level abstraction on top of DataSource to perform database operations. In addition to that Spring’s declarative Transaction Management capabilities helps to manage database transactions in a simplified way without having to write boilerplate code.

Introducing Spring Profiles

Typically, software applications run in different environments. During development, it will be local, and then we may deploy it on QA, Staging, Performance and finally in Production environments. You may have to configure your application with different configuration properties while running the application in different environments.

Logging is a common and important requirement for running applications in production. Spring Boot provides great support for application logging out of the box and offers various customization options. In this tutorial, you will learn how to implement logging in your Spring Boot application using Logback and Log4j2.

In the previous Spring Boot Testing Tutorial, we have learned how to write unit, slice and integration tests for a Spring Boot application.

In this tutorial, you will learn how to configure your Spring Boot application using properties and YAML files for running the application in different environments.

In the previous Getting Started with Spring Boot tutorial, we have learned how to create a Spring Boot application and built a simple REST API.

In this tutorial, you will learn how to write unit, slice and integration tests for your Spring Boot application.

Introducing Spring Boot

Spring Boot is the most popular framework for building applications in the Java world. Spring Boot is an Opinionated and Convention Over Configuration based approach to building Spring framework based applications.

Using Spring Boot, you can build different kinds of applications such as monolithic applications, microservices, serverless applications, Batch applications, etc.

TLDR;

I am happy to announce that I am starting the SpringBoot - The Missing Guide video series on my SivaLabs YouTube Channel. This SpringBoot - The Missing Guide video series is for those who need help understanding SpringBoot’s magic. In this series, I will explain the core concepts used in Spring and SpringBoot with practical examples.

Spring Framework 6 implemented the Problem Details for HTTP APIs specification, RFC 7807. In this article we will learn how to handle exceptions in SpringBoot 3 REST API(which uses Spring Framework 6) and provide error responses using ProblemDetails API.
