我有一个Primefaces JSF项目，并使用以下内容注释我的bean：
@Named("reportTabBean")
@SessionScoped
public class ReportTabBean implements Serializable {
...
}
bean创建各种选项卡，树等。在用户可以访问应用程序之前，需要使用Shiro框架进行登录。由于某种原因，每个浏览器会话共享相同的选项卡，树等以及它们的状态。就像bean是应用程序范围一样。我尝试了不同的范围而没有任何运气。但是，用户主体不是共享的。我正在获取正确的登录用户。
我试过了两次
@javax.enterprise.context.SessionScoped
和
@javax.faces.bean.SessionScoped
没有运气。
我做错了什么？
修改
我正在使用JDK 1.6.32。
这是其中一个豆子：
@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但是我的范围并不重要。它表现为应用范围。如果我在用户A登录的Chrome中的某一点打开手风琴，那么用户B的Firefox手风琴中的同一点也将被打开。手风琴菜单定义如下：
<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>

由于您使用的是@Named，因此您应该使用来自CDI的@SessionScoped包中的javax.enterprise.context。
由于某种原因，每个浏览器会话共享相同的选项卡，树等以及它们的状态。这就像bean是应用程序范围
访问同一个Web应用程序的每个浏览器选项卡都将共享同一个用户会话，因此@SessionScoped bean的行为不是@ApplicationScoped。如果您在不同的浏览器中打开相同的Web应用程序，可以注意到这一点Chrome和Firefox，您将看到您正在使用两个完整的不同会话。
根据您的问题说明，您需要使用@ViewScoped。如果您正在使用Java EE 7，则可以使用JSF 2.2附带的此范围：@javax.faces.view.ViewScoped。如果您使用的是Java EE 6或更早版本，最简单的解决方案是使用@ViewScoped from OmniFaces（请注意，至少需要OmniFaces 1.6）或使用@ViewScoped from MyFaces CODI。

修正了它！事实证明这是因为我使用Spring我需要使用Spring的范围注释而不是JSF。
@Scope("session")
而不是
@SessionScoped
我从this thread找到了解决方案。
