Mocking is an essential part of unit testing, and the Mockito library makes it easy to write clean and intuitive unit tests for your Java code.
Get started with mocking and improve your application tests using our Mockito guide:
Handling concurrency in an application can be a tricky process with many potential pitfalls. A solid grasp of the fundamentals will go a long way to help minimize these issues.

Spring 5 added support for reactive programming with the Spring WebFlux module, which has been improved upon ever since. Get started with the Reactor project basics and reactive programming in Spring Boot:
Since its introduction in Java 8, the Stream API has become a staple of Java development. The basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use.
But these can also be overused and fall into some common pitfalls.
To get a better understanding on how Streams work and how to combine them with other language features, check out our guide to Java Streams:

Yes, Spring Security can be complex, from the more advanced functionality within the Core to the deep OAuth support in the framework.
I built the security material as two full courses - Core and OAuth, to get practical with these more complex scenarios. We explore when and how to use each feature and code through it on the backing project.

End-to-end testing is a very useful method to make sure that your application works as intended. This highlights issues in the overall functionality of the software, that the unit and integration test stages may miss.
Playwright is an easy-to-use, but powerful tool that automates end-to-end testing, and supports all modern browsers and platforms.
When coupled with LambdaTest (an AI-powered cloud-based test execution platform) it can be further scaled to run the Playwright scripts in parallel across 3000+ browser and device combinations:

1. Overview
By default, Spring Boot displays a banner on application start-up. The banner is an ASCII art representation of the word ‘Spring‘. However, we can replace this with a custom ASCII art banner.
In this tutorial, we’ll learn how to create a custom banner using ASCII art.
2. Creating a Banner
First, let’s create ASCII art banner using a combination of characters such as @, #,*, and 8 to form the Baeldung logo:
Next, let’s save the ASCII art as banner.txt and place it in the root of the resources folder. Spring Boot automatically detects the banner.txt in this location and uses it instead of the default banner.
3. Using the Custom Banner
In the previous section, we created an ASCII art banner and placed it in the resources folder for automatic detection by Spring Boot.
However, if we want to use a different file name or location, we can specify the banner location using the spring banner.location property in the application.properties file:
spring.banner.location=classpath:/path/to/banner/bannername.txtHere, we specify the path to the custom ASCII art banner.
3.1. Image Support Before Spring Boot 3.0.0 M2
Before Spring Boot version 3.0.0 M2, we could use image banners in formats such as .gif, .png, and .jpg. Like banner.txt, Spring Boot expects this file to be named banner.gif, banner.png, or banner.jpg.
Alternatively, we could place the image in a custom location and reference it using the spring.banner.image.location property in the application.properties:
spring.banner.image.location=classpath:banner.gifPreferably, a text-based banner is better because an image banner could increase the application start-up time based on the complexity of the image used.
Starting from Spring Boot version 3.0.0 M2, image formats such as GIF, JPEG, and PNG are no longer supported, leaving the banner.txt format as the only supported format.
4. Conclusion
In this article, we saw how to create and use a custom ASCII art banner in Spring Boot applications.
