10.2.7.2. Use Named Beans

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"));
  }
}

@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"));
  }
}

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.

Use the named bean in a JSF view.

<h:form>
  <h:commandButton value="Welcome visitors" action="#{greeter.welcomeVisitors}"/>
</h:form>

<h:form>
  <h:commandButton value="Welcome visitors" action="#{greeter.welcomeVisitors}"/>
</h:form>

Result:

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