How to name a bean with Java annotation?

Java annotations themselves cannot directly name a Bean. Bean naming is usually achieved by using naming conventions on classes, specifying the Bean’s ID in configuration files, or using Spring annotations.

1. Naming convention: According to Java naming conventions, class names are usually written in camel case with a lowercase first letter. For example, for a class named “Student,” the bean name can be “student.”
2. Specify the ID of the bean in the configuration file: In XML configuration files, you can use the id attribute of an element to specify the ID of the bean. For example:
3. Create a bean with the id “studentBean” that uses the class com.example.Student.
4. Here the Bean of the Student class is named “studentBean”.
5. You can use annotations in Spring such as @Named or @Component to name a Bean. For example:
6. public class StudentBean {
   …
   }
7. Alternatively:
8. Create a class named “Student” with the component name “studentBean”.
9. Here we are naming the Bean of the Student class as “studentBean”.

It is important to note that if a Bean’s ID is not explicitly specified or named using annotations, Spring will automatically generate a default Bean name based on certain naming conventions.
