And, you still get access to all Spring Framework features, including easy event handling, validation, data binding, type conversion, and built-in security and testing capabilities. You still are able to use Spring Framework’s very popular annotation system that lets you easily inject extra dependencies (not covered by Spring Starters) into your application. In theory, this comes at the expense of the greater flexibility you get from working directly with Spring Framework.īut, in practice, unless you need or want to implement a very unique configuration, using Spring Booth is worth the tradeoff. Spring FrameworkĪgain, the biggest advantages of using Spring Boot versus Spring Framework alone are ease of use and faster development. (You can opt out of this feature to build applications without an embedded Web server.) Spring Boot vs. As a result, you can launch your application on any platform by simply hitting the Run command. Specifically, it lets you create standalone applications that run on their own, without relying on an external web server, by embedding a web server such as Tomcat or Netty into your app during the initialization process. ![]() Spring Boot helps developers create applications that just run. Spring Boot includes over 50 Spring Starters, and many more third-party starters are available. ‘Spring Security’ is another popular starter dependency that automatically adds authentication and access-control features to your application. You run Spring Boot Initializr by filling out a simple web form, without any coding.įor example, the ‘Spring Web’ starter dependency allows you to build Spring-based web applications with minimal configuration by adding all the necessary dependencies-such as the Apache Tomcat web server-to your project. You can define the needs of your project during the initialization process, during which you choose among multiple starter dependencies-called Spring Starters-that cover typical use cases. Following its own judgment, Spring Boot chooses which packages to install and which default values to use, rather than requiring you to make all those decisions yourself and set up everything manually. Spring Boot uses an opinionated approach to adding and configuring starter dependencies, based on the needs of your project. Even though you can override these defaults once the initialization is complete, Java Spring Boot's autoconfiguration feature enables you to start developing your Spring-based applications fast and reduces the possibility of human errors. As Java Spring Boot comes with built-in autoconfiguration capabilities, it automatically configures both the underlying Spring Framework and third-party packages based on your settings (and based on best practices, which helps avoid errors). AutoconfigurationĪutoconfiguration means that applications are initialized with pre-set dependencies that you don't have to configure manually. Spring Boot mitigates this effort with three important capabilities. What Spring Boot adds to Spring FrameworkĪs capable and comprehensive as Spring Framework is, it still requires significant time and knowledge to configure, set up, and deploy Spring applications. In sum, Spring Framework provides developers with all the tools and features the need to create loosely coupled, cross-platform Java EE applications that run in any environment. It integrates with various Java EE technologies such as RMI (Remote Method Invocation), AMQP (Advanced Message Queuing Protocol), Java Web Services, and others. Spring Framework also offers built-in support for typical tasks that an application needs to perform, such as data binding, type conversion, validation, exception handling, resource and event management, internationalization, and more. This enables developers to create modular applications consisting of loosely coupled components that are ideal for microservices and distributed network applications. Spring Framework offers a dependency injection feature that lets objects define their own dependencies that the Spring container later injects into them. ![]() These features work together to provide you with a tool that allows you to set up a Spring-based application with minimal configuration and setup.
