10.2.7.2. Use Named Beans

  1. Use the @Named annotation to assign a name to a bean.

    @Named("greeter")
public class GreeterBean {
  private Welcome welcome;

  @Inject
  void init (Welcome welcome) {
    this.welcome = welcome;
  }

  public void welcomeVisitors() {
    System.out.println(welcome.buildPhrase("San Francisco"));
  }
}
    Copy to Clipboard Toggle word wrap
    The bean name itself is optional. If it is omitted, the bean is named after the class name, with the first letter decapitalized. In the example above, the default name would be greeterBean.

  2. Use the named bean in a JSF view.

    <h:form>
  <h:commandButton value="Welcome visitors" action="#{greeter.welcomeVisitors}"/>
</h:form>
    Copy to Clipboard Toggle word wrap
Result:

Your named bean is assigned as an action to the control in your JSF view, with a minimum of coding.
