![]() ![]() We can use this annotation with a constructor, setter, or field injection. is used to mark a dependency which Spring is going to resolve and inject automatically. If specific packages are not defined, scanning will occur from the package of the class that declares this annotation. is also used to specify base packages using basePackageClasses or basePackage attributes to scan. is used with annotation to allow Spring to know the packages to scan for annotated components. A Java class annotated with is a configuration by itself and will have methods to instantiate and configure the dependencies. is an analog for an XML configuration file – it is configured using Java classes. Spring Core Annotations is used on classes that define beans. Let’s look at all the annotations provided by the Spring Framework. With Spring Boot, we can do almost everything with annotations. Spring Framework started out with XML configuration and over time it has introduced many capabilities to reduce code verbose and get things done quickly. Nowadays, there are so many spring annotations that it could become overwhelming. ![]() 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. The ability to create standalone applications.An opinionated approach to configuration.Java Spring Boot (Spring Boot) is a tool that makes developing a web application and microservices with Spring Framework faster and easier through three core capabilities: Java Spring Framework (Spring Framework) is a popular, open-source, enterprise-level framework for creating standalone, production-grade applications that run on the Java Virtual Machine (JVM). ![]()
