Where is javax inject named

If you want to create annotations that act like Named , use the Qualifier annotation when creating them. Those JSR standard annotations are scanned and retrieved the same way as Spring annotation as long as the following jar is in your classpath. This package provides dependency injection annotations that enable portable classes, but it leaves external dependency configuration up to the injector implementation.

So it's up to the provider to determine which objects are available for injection. In the case of Spring it is all Spring beans. The primary role of the Named annotation is to define a bean for the purpose of resolving EL statements within the application, usually through JSF EL resolvers. Injection can be performed using names but this was not how injection in CDI was meant to work since CDI gives us a much richer way to express injection points and the beans to be injected into them.

My questions are: What is the difference between Named and Qualifier How are you supposed to tell the Runtime system a class should be injectable in other classes what's the annotation for that?

The equivalent of Component in Spring? The fields and methods of the parent class are injected into the fields and methods that take precedence over the subclasses, and the fields and methods in the same class are not sequential. The constructor of the Inject annotation can be a constructor with no parameters or multiple parameters. Inject annotates at most one constructor per class. In Spring 3. I feel that if I leave Spring environment, I should instantiate new objects every time.

Of course, according to the different jar packages implemented, otherwise the Singleton annotation under javax. It's useless. The Named and Spring's Component functions are the same. Named can have a value, and if there is no value, the default Bean name is the same as the class name. In the case of Spring it is all Spring beans.
