java - jsf中不能调用Bean？

Question

我正在使用 jave 的 JSF 框架。我有一个问题。当我使用 url-pattern 是 /faces/* 时，我可以调用 bean。但是当我将 url-pattern 更改为 *.xhtml 时，我不能。我必须如何解决这个问题。

@ManagedBean
@Named(value = "employerBean")
@SessionScoped
public class EmployerBean implements Serializable {

//    private final static EmployerService epmservice = new EmployerService();

    /**
     * Creates a new instance of EmployerBean
     */
    public EmployerBean() {
    }


    public List<String> getCompanies() {
        List<String> messages = Arrays.asList("Hello", "World!", "How", "Are", "You");
        return messages;
    }
}
