Spring Boot 3

Introduction: In software development, reusing configurations is a smart way to keep your code clean and modular. If you’re working with Spring Boot 3, there are some handy annotations you can use to import existing configurations into your project. In this blog post, we’ll explore how to use @Import and @ImportResource to achieve this. Importing Java Configurations with @Import: The @Import annotation is used to bring in configurations from other Java classes. This is especially useful when you have common configurations that you want to reuse across multiple applications. ...

Logging is an essential aspect of any application, providing critical insights and aiding in debugging and monitoring. In a Spring Boot 3 application, you can easily configure log levels for specific loggers to control the verbosity of logs for different packages or classes. In this blog, we’ll explore how to achieve this using properties files, YAML configuration, and programmatic approaches for both Logback and Log4j. Table of Contents Introduction Using application.properties Using application.yml Programmatic Configuration Customizing Logback Configuration Configuring Log4j Conclusion Introduction Spring Boot uses Logback as the default logging framework, but it also supports Log4j2. You can choose the logging framework that best fits your needs. In this blog, we’ll cover configuration for both Logback and Log4j. ...

Why Externalize Configuration? Externalizing configuration in Spring Boot means separating configuration parameters from the code. This separation allows the same application code to be used in different environments by simply changing the configuration rather than the code, reducing the risk of bugs and simplifying the deployment process. 1. Using application.properties or application.yml Spring Boot’s default approach for configuration is through the application.properties or application.yml files located under src/main/resources. These files are automatically loaded by Spring Boot and can be used to define properties accessible throughout the application. ...

Understanding how to create and manage these beans effectively is crucial for leveraging the full power of Spring Boot. In this blog post, we’ll dive into the various methods available for bean creation, focusing on annotations like @Component, @Service, @Repository, @Controller, and @Bean. What is a Bean in Spring Boot? In Spring Boot, a “bean” is an object that is instantiated, assembled, and otherwise managed by the Spring IoC (Inversion of Control) container. Beans are the building blocks of your application, and managing them properly allows Spring to tie your application together through dependency injection. ...

In this post, we dive deep into one of Spring Boot’s core annotations: @SpringBootApplication. We will explore its components, usage, and some advanced configurations. Whether you’re new to Spring Boot or looking to deepen your understanding of this pivotal annotation, this article will provide you with valuable insights. Understanding @SpringBootApplication Overview @SpringBootApplication is a convenience annotation that encapsulates three major annotations: @Configuration, @EnableAutoConfiguration, and @ComponentScan. Let’s break down each to see how they contribute to simplifying your Spring Boot application setup. ...
