Mojarra JSF 中的闪存异常

【中文标题】Mojarra JSF 中的闪存异常

【英文标题】：Exception about flash in Mojarra JSF

【发布时间】：2013-07-14 04:30:36

【问题描述】：

我升级到 Mojarra JSF 2.2.1（从 2.1.22 开始），从那时起，对于我的每个请求，我在控制台中都遇到了异常：

GRAVE: JSF1094: Could not decode flash data from incoming cookie value /?.  
Processing will continue, but the flash is unavailable for this request.
com.sun.faces.lifecycle.InvokeApplicationPhase execute

当我没有在其上使用 Flash 范围时，请求成功完成。但是，由于我将此范围用于FacesMessages，因此如果我在此处输入一条消息，我就会有一个NullPointerException 并且导航流程被中断：

GRAVE: El Servlet.service() para servlet Faces Servlet lanzó una excepción

我对 2.1.x 分支 (2.1.24) 的最新版本也有同样的问题。顺便说一句，这就是我的addInfoMessage 方法的作用：

/**
 * Add information message.
 * 
 * @param msg
 *            the information message
 */
public void addInfoMessage(String msg) 
    addInfoMessage(null, msg);


/**
 * Add information message to a specific client.
 * 
 * @param clientId
 *            the client id
 * @param msg
 *            the information message
 */
public void addInfoMessage(String clientId, String msg) 
    Messages.addFlashInfo(clientId, msg);

作为Messages 类的org.omnifaces.util.Messages 类型。

当我清除浏览器的 cookie 时，该问题仅在 firefox 和涉及视图参数时发生，似乎消失了。它似乎也持续存在于整个 2.2.x 和 2.1.x 分支中（至少到 2.2.4-2.1.26），显示略有不同的痕迹：

com.sun.faces.context.flash.ELFlash getCurrentFlashManager 坟墓：JSF1094：无法从传入的 cookie 值解码闪存数据 解密值中的字符无效。处理将继续，但闪存不适用于此请求。

根据@BalusC here（2013 年 8 月）：

我们在 Mojarra 2.1.24 中也遇到过这种情况。我们得出的结论是 ELFlash 课程 - 老实说 - 一个可怕的烂摊子，似乎最初是由一个没有扎实的 HTTP 问题背景知识的实习生编写的。

【问题讨论】：

我也有同样的问题。当存在活动闪存并且您重新启动服务器时，这似乎会发生。如果您清除浏览器 cookie（用于您的 url），那么它就会消失。

【参考方案1】：

我可以在任何浏览器上重现问题。我刚刚打开https://java.net/jira/browse/JAVASERVERFACES-2973 来解决这个问题。

【讨论】：

绝对是bug。

似乎他们在 2.1.25 中修复了它。但是，我仍然遇到问题，因为插入的闪存值在两个以上的请求中仍然存在。我使用 POST-REDIRECT-GET 模式。

【参考方案2】：

我没有足够的代表发表评论，所以我写一个答案....

正如 Stan Silvert 所说，它发生在任何浏览器上。 2.1.25 正在修复它，但 https://java.net/jira/browse/JAVASERVERFACES-2862 已在 2.1.27 上修复 2.1.x 分支：https://java.net/jira/browse/JAVASERVERFACES-3089

2.1.27 的截止日期为 2014 年 1 月 2 日。

【参考方案3】：

我认为 Mojarra 2.2.2 / 2.1.25 会解决这个问题，考虑到：https://java.net/jira/browse/JAVASERVERFACES-2955

【讨论】：

那个bug是关于IE的，我用的是火狐
