JSF @Named 目标不可达，标识符'*bean*'解析为空

Question

我检查了许多其他有类似问题的线程，但我找不到这个线程有什么问题。CDI @Named与@ManagedBean不冲突。这是我使用的bean类。

@Named
@RequestScoped
public class UserBean {
    private String name;
    public UserBean() {
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String addValuesToFlashAction() {
        Flash flash = FacesContext.getCurrentInstance()
                .getExternalContext().getFlash();
        flash.put("name", name);
        return "terms?faces-redirect=true";
    }
    public void pullValuesFromFlashAction(ComponentSystemEvent e) {
        Flash flash = FacesContext.getCurrentInstance()
                .getExternalContext().getFlash();
        this.name = (String) flash.get(name);
    }
...
}

这是xhtml索引页的正文

<h:body>
    <f:metadata>
        <f:event type="preRenderView"
                 listener="#{userBean.pullValuesFromFlashAction}"/>
    </f:metadata>
    <h:messages/>
    <h:form>
        Name: <h:inputText value="#{userBean.name}"/>
        <h:commandButton value="Register" 
                         action="#{userBean.addValuesToFlashAction()}"/>
    </h:form>
</h:body>

当我运行这个，我有/flashIndex.xhtml @12,72 listener="#{userBean. html":目标不可达，标识符'userBean'解析为null，并且在glassfish日志中抛出javax.el.PropertyNotFoundException

已解决:我导入了javax.faces.bean。javax.enterprise.context.RequestScoped
