會話範圍的bean不是一個會話範圍的bean

Question

我有一個Primefaces JSF項目，並與下面的註解我的豆子：

@Named("reportTabBean") 
@SessionScoped 
public class ReportTabBean implements Serializable { 
... 
} 

豆創建各種選項卡，樹木等的登錄使用四郎框架需要在用戶可以訪問應用程序之前。出於某種原因，每個瀏覽器會話共享相同的選項卡，樹等等以及它們的狀態。這就像bean是應用程序範圍。我嘗試了不同的示波器，沒有任何運氣。但是，用戶主體不共享。我收到了正確的登錄用戶。

我都試過

@javax.enterprise.context.SessionScoped

和

@javax.faces.bean.SessionScoped

沒有運氣。

我在做什麼錯？

我使用JDK 32年6月1日。

這裏的咖啡豆之一：

@Named("reportTabBean") 
@ViewScoped 
public class ReportTabBean implements Serializable { 
    private Map<String, TreeNode> model; //Accordian menu which I want initiated upfront 
    private int      activeReportTypeIndex; 
    private TreeNode    selectedNode; 
    .... 
    @PostConstruct 
    public void createModel() { 
     model = treeService.createModel(); 
    } 

    public Map<String, TreeNode> getModel() { 
     return model; 
    } 
    .... 
    public void tabIsChanged(TabChangeEvent event) { 
     FacesContext context = FacesContext.getCurrentInstance(); 
     Map<String, String> params = context.getExternalContext().getRequestParameterMap(); 
     AccordionPanel tabView = (AccordionPanel) event.getComponent(); 
     String activeIndexValue = params.get(tabView.getClientId(context) + "_tabindex"); 

     this.activeReportTypeIndex = Integer.parseInt(activeIndexValue); 
    } 

    public void onNodeSelect(final NodeSelectEvent event) { 
     FacesContext.getCurrentInstance().getExternalContext().getSession(true); 

     try { 
      tabs.add(new ReportListTab(
       event.getTreeNode().getData().toString(), 
       reportService.getReports(
         ((FolderTreeNodeImpl) event.getTreeNode()).getReportType(), 
         ((FolderTreeNodeImpl) event.getTreeNode()).getFolderID() 
         ) 
       ) 
       ); 
     } catch (HibernateException e) { 
      LOGGER.error("[onNodeSelect] HibernateException", e); 

      FacesContext.getCurrentInstance().addMessage(":messages", 
       new FacesMessage(
         FacesMessage.SEVERITY_ERROR, 
         "Fatal Error", 
         "Please try again. If the error occurs, please contact the administrator." 
       ) 
       ); 
     } 
} 


} 

@ViewScoped是org.omnifaces.cdi.ViewScoped但不要緊什麼範圍，我沒有。它表現爲應用程序範圍。如果我以用戶A的身份登錄Chrome並在一點處打開手風琴，則用戶B的Firefox手風琴中的同一點也將被打開。摺疊式菜單定義如下：

<h:form>        
     <p:accordionPanel value="#{reportTabBean.model.keySet().toArray()}" var="reportType" activeIndex="#{reportTabBean.activeReportTypeIndex}"> 

      <p:ajax event="tabChange" listener="#{reportTabBean.tabIsChanged}" /> 

      <p:tab title="${msg[reportType]}"> 

       <p:tree value="#{reportTabBean.model[reportType]}" var="node" dynamic="true" 
        cache="true" selectionMode="single" selection="#{reportTabBean.selectedNode}" id="tree"> 

        <p:ajax event="select" update=":tabViewForm" listener="#{reportTabBean.onNodeSelect}" /> 

        <p:treeNode type="node" expandedIcon="folder-open" collapsedIcon="folder-collapsed"> 
         <h:outputText value="#{node}" /> 
        </p:treeNode> 

        <p:treeNode type="leaf" icon="document-node"> 
         <h:outputText value="#{node}" /> 
        </p:treeNode> 

       </p:tree> 

      </p:tab> 
     </p:accordionPanel> 
    </h:form>

Answer 1

定了！原因是我使用Spring我需要使用Spring的範圍註釋而不是JSF。

@Scope("session") 

而不是

@SessionScoped 

我找到了解決辦法，從this thread。

Answer 2

由於您使用@Named你應該使用@SessionScoped從javax.enterprise.context包，從CDI。

由於某種原因，每個瀏覽器會話共享相同的選項卡，樹等等以及它們的狀態。這就像豆類應用範圍

每一個瀏覽器選項卡訪問同一個Web應用程序將共享相同的用戶會話，所以@SessionScoped豆不表現爲@ApplicationScoped。如果您在不同的瀏覽器中打開相同的Web應用程序，可以注意到這一點Chrome和Firefox，你會看到你正在使用兩個完整的不同會話。

通過描述您的問題，您需要使用@ViewScoped。如果您正在使用Java EE 7，則可以使用JSF 2.2附帶的此範圍：@javax.faces.view.ViewScoped。如果您正在使用Java EE 6或之前的版本，最簡單的解決方案將使用@ViewScoped from OmniFaces（請注意，您至少需要OmniFaces 1.6）或使用@ViewScoped from MyFaces CODI。
