How to Create a CDI Bean

Ahoy there matey! Are you ready to learn how to create a CDI bean? Well, look no further because I’m here to guide you through the process. In this article, we’ll cover how to use the @Named annotation to specify the name of the bean.

What is a CDI bean?

Before we dive into the specifics of creating a CDI bean, let’s first make sure we understand what a CDI bean is. In a nutshell, a CDI bean is a managed bean that is created and managed by the Contexts and Dependency Injection (CDI) container.

CDI beans have many benefits, including modularity and extensibility. They can be easily integrated with other CDI beans and external libraries, making them a powerful tool for building complex applications. Compared to other frameworks, CDI is flexible and allows for a high degree of customization.

Using the @Named annotation

To create a CDI bean, you need to annotate a Java class with the @Named annotation. This annotation specifies the name of the bean that will be used to reference it in other parts of your code.

@Named("myBean")
public class MyBean {
  // class code here
}

In the example above, we’ve created a CDI bean called MyBean and specified its name as "myBean" using the @Named annotation. Now we can use the name "myBean" to reference this bean in other parts of our code.

The @Named annotation can also be used without an argument. In this case, the name of the bean is inferred from the name of the class.

@Named
public class MyBean {
  // class code here
}

In the example above, the name of the CDI bean will be inferred as "myBean" based on the name of the class.

Conclusion

Creating a CDI bean is a simple process, made even simpler with the use of the @Named annotation. By specifying the name of the bean, we can easily reference it in other parts of our code.

Now that you know how to create a CDI bean, you’re one step closer to becoming a master Java developer. Keep exploring and experimenting with CDI to discover all the possibilities it has to offer! Until next time, matey!
