Understanding the Difference Between Managed Beans and CDI Beans in JSF

In JavaServer Faces (JSF), a key distinction to note is the difference between managed beans and CDI beans.

Managed Beans

Managed beans in JSF are traditional Java beans that are managed by the JSF framework. They are typically defined using the @ManagedBean annotation or configured in the faces-config.xml configuration file. Managed beans are initialized by the JSF framework and can be used for handling the business logic in JSF applications.

CDI Beans

CDI (Context and Dependency Injection) beans, on the other hand, are part of the CDI specification introduced in Java EE. CDI beans offer more sophisticated dependency injection capabilities and are managed by the CDI container. CDI beans are typically defined using annotations such as @Named and @Inject.

Overall, the main difference between managed beans and CDI beans in JSF lies in their management and dependency injection mechanisms, with CDI beans offering more advanced features and flexibility.

For optimal performance and maintainability in JSF applications, understanding the distinctions between managed beans and CDI beans is crucial for effective bean management and dependency injection.
