在JSF中使用HttpServlet会话属性

jsf session servlets jpa

在JSF中使用HttpServlet会话属性,jsf,session,servlets,jpa,ejb,Jsf,Session,Servlets,Jpa,Ejb,如何在JSF中使用会话属性（该属性是通过第三方HttpServlet获得的，如下所示），以便将其显示给用户并与表单中的其他值一起存储 HttpServlet（通过第三方登录资源远程获取的对象）： JSF（表格）： 在我的JSF中： <p:outputLabel value="UserID (the sessionAttribute):" for="userID" /> <p:inputText id="userID" value="#{userBean.myUser.xChav

如何在JSF中使用会话属性（该属性是通过第三方HttpServlet获得的，如下所示），以便将其显示给用户并与表单中的其他值一起存储

HttpServlet（通过第三方登录资源远程获取的对象）：

JSF（表格）：

在我的JSF中：

<p:outputLabel value="UserID (the sessionAttribute):" for="userID" />
<p:inputText id="userID" value="#{userBean.myUser.xChave}" title="userID" />

<p:outputLabel value="Type the Reason:" for="reason" />
<p:inputText id="reason" value="#{viagensController.selected.reason}" />
使用
FacesContext.getCurrentInstance（）.getExternalRequest（）
，可以将其类型转换为
HttpServletRequest
。从那里您可以访问会话。

John Ament，我已经尝试过了，但没有成功。请查看我尝试过的代码更新并给我帮助。Hmmm。因此，首先，
myUser
的getter非常危险。调用时，您总是创建一个新实例。使用一个实例变量，让post构造完成它的工作。你能包括这个新类的导入语句吗？嗨，John Ament。我将导入放在更新代码部分。我把一个Netbeans（称为iro）项目放在：Ah-ha下载。您需要一致地使用CDI注释或JSF注释。以这种方式混合会导致您面临的问题类型。好的。但是我该怎么办呢？我需要换包裹吗？注释？谢谢。你使用什么j2ee版本？你的UserBean创建了吗？嗨，jjd。所以，我猜UserBean是实例化的，因为它是通过注释声明的——我忘记了JSR，我正在使用的JEE7+Glassfish 4支持的较新的泛型bean管理机制，对吗？完整的（Netbeans）项目可在上获得。谢谢。如果声明了它，并不意味着它已实例化。你调试过了吗？有些情况可能并非如此。例如，CDI不起作用。我了解到ManagedBean是按需实例化的，而不是以前，所以如果它从未在显示视图的xhtml中引用过，它就不会被实例化。如果非JSF代码需要bean，它必须手动构造并初始化它，然后将其放置在HttpSession对象中。JSF代码将在HttpSession中看到它，并且不会尝试重新实例化它，JSF和非JSF代码可以根据通常的线程安全考虑愉快地共享它。因此，我认为只要在view.xhtml中引用#{userBean.userID}就可以实例化MB。你怎么认为？谢谢。嗨，jjd。正如约翰·阿门特（John Ament）在下文中所示，问题是关于进口包装的问题，该问题已得到解决。但现在，问题在于将用户会话属性与用户通知的其他值一起存储在数据库中。（请参见上面的更新代码）。欢迎你的帮助。谢谢
