Answer 
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.
