The central artifacts in Spring's Java configuration support are @Configuration -annotated classes and @Bean -annotated methods. The @Bean annotation is used to indicate that a method instantiates, configures, and initializes a new object to be managed by the Spring IoC container.

The `@Bean` annotation in the Java Spring framework is used to indicate that a method produces a bean that should be managed by the Spring container. It is typically used within a configuration class annotated with `@Configuration`. ### Key Uses: 1. **Bean Creation**: Defines a method that returns an object to be registered as a Spring bean. 2. **Configuration Management**: Allows for explicit configuration of beans, specifying properties and dependencies. 3. **Dependency Injection**: Beans created with `@Bean` can have their dependencies automatically injected by Spring. ### Example: ```java @Configuration public class AppConfig { @Bean public MyService myService() { return new MyService(); } } ``` In this example, the `myService` method creates and returns an instance of `MyService`, which is registered as a bean in the Spring application context. This allows other components to use `MyService` through dependency injection. read less
