Get List of All Managed Beans in JSF at runtime

Question

I'd like to get a list of all managed beans in a JSF application. In Spring, I can do something like context.getBeansOfType(). Is there a corresponding method in JSF?

I have a number of @ManagedProperty beans that implement an interface. I'd like to get a list of these adapters and loop through them rather than invoke each bean explicitly in order to keep the code clean.

Thank you

You can do this with BeanManager class from com.sun.faces.mgbean package:

ApplicationAssociate application = ApplicationAssociate.getInstance(FacesContext.getCurrentInstance().getExternalContext());
BeanManager beanManager = application.getBeanManager();
Map<String, BeanBuilder> beanMap = beanManager.getRegisteredBeans();
Set<Entry<String, BeanBuilder>>beanEntries = beanMap.entrySet();

for (Entry<String, BeanBuilder> bean: beanEntries) {
  String beanName = bean.getKey();
  if (beanManager.isManaged(beanName)) {
    BeanBuilder builder = bean.getValue();
    System.out.println("Bean name: " + beanName);
    System.out.println("Bean class: " + builder.getBeanClass());
    System.out.println("Bean scope: " + builder.getScope());
  }
}

NOTE: This is tightly coupled with Mojarra JSF implementation and doesn't work on other implementations.
