Most Spring Boot applications start with a beautifully boring main class.

Then one day we need caching. We add @EnableCaching.

Then we need async processing. We add @EnableAsync.

Then scheduling. Then JPA auditing. Then maybe something else.

Before we know it, the main class has become the place where every framework feature goes to live.

At first glance, this feels harmless. The application starts. The feature works. Everybody moves on.

This works great… until a slice test gets involved.

Let’s look at why adding every @EnableXXX annotation to the Spring Boot main class can make your tests more fragile, and what I prefer to do instead.

A Value Object is a domain concept defined by its values rather than by identity. For example, we can represent EventId, EventCode or Email as a value object. In this article, let’s explore the benefits of using value objects over primitive types.

As a Java Developer Advocate at JetBrains, I frequently demonstrate IntelliJ IDEA features through videos and articles. To do this, I usually create small demo applications focused on specific features. While this works well initially, the number of such applications grows quickly. Soon, it becomes difficult to remember which app was built for what purpose, turning it into a maintenance headache.

ChatGPT and other Generative AI tools took the world by a storm. People are using these AI tools for various purposes such as to explore a topic, to seek answers to their questions or to get help in coding, etc. ChatGPT and Google’s Gemini are very popular AI tools that are available for free with some usage limitations.

Spring Boot 3.1.0 introduced support for Testcontainers to simplify local development and testing. Testcontainers helps in writing tests using real dependencies instead of mocks, but it may also increase the test execution time.

If you ever worked with Spring Boot, then you are probably aware of Spring Initializr. The Spring Initializr is a web application that you can use to create a Spring Boot application.

Do you know Spring Initializr itself is an open-source Spring Boot application? You can fork it, customize it, deploy on your infrastructure and use it to generate Spring Boot applications.

Spring Boot is the most popular framework in the Java world to build enterprise applications. Also, Spring Boot is the most sought-after skill to get hired as a Java developer.

Here is my recommended approach to learn Spring Boot.

Typically, in Spring Boot + Thymeleaf applications, we use thymeleaf-layout-dialect to define the common layout of the web pages and it works fine.

But when we compile the Spring Boot application to GraalVM native image, it is failing due to this error. I tried many suggestions mentioned in the above issue, but none of them worked for me.
