JSF1094错误在cluster env中使用闪存时发生了

发布于 2025-01-26 00:52:46 字数 831 浏览 2 评论 0原文

我在集群Env（Alb + Two Wildfly 17 +可分布设置）中使用PrimeFaces 11。当我使用Flash从Page1传递参数到Page2时，我会收到以下错误，并且不能传递参数。

 [javax.enterprise.resource.webcontainer.jsf.flash] (default task-29) JSF1094: Could not decode flash data from incoming cookie value Invalid characters in decrypted value.  Processing will continue, but the flash is unavailable for this request.

如果我仅在一台服务器中运行它，则可以正常传递参数。

设置数据

  flash flash = faceScontext.getCurrentInstance（）.getExternalContext（）。getflash（）;
 flash.put（redirect_data_key，rdata）;

获取数据

  flash flash = faceScontext.getCurrentInstance（）.getExternalContext（）。getflash（）;
 返回（redirectData）flash.get（redirect_data_key）;

我如何解决？

I am using primefaces 11 in a cluster env(alb + two wildfly 17 + distributable setting).
when I use Flash to pass parameter from page1 to page2, I got the following error, and the parameters can no be passed.

 [javax.enterprise.resource.webcontainer.jsf.flash] (default task-29) JSF1094: Could not decode flash data from incoming cookie value Invalid characters in decrypted value.  Processing will continue, but the flash is unavailable for this request.

If I run it in only one server, the parameters can be passed normally.

set data

 Flash flash = FacesContext.getCurrentInstance().getExternalContext().getFlash();
 flash.put(REDIRECT_DATA_KEY, rData);

get data

 Flash flash = FacesContext.getCurrentInstance().getExternalContext().getFlash();
 return (RedirectData) flash.get(REDIRECT_DATA_KEY);

How I can solve it?

JSF/FlashSecretkey是Base64编码AES 256BIT键，用于加密闪存示波器cookie（例如CSFCFC = K8AUYBA％3D;。
键可以通过以下代码生成：

import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import java.security.NoSuchAlgorithmException;
import java.util.Base64;

public class Main {
    public static void main(String ... args) throws NoSuchAlgorithmException {
        KeyGenerator keyGen = KeyGenerator.getInstance("AES");
        keyGen.init(256); // key length is 256 byte
        SecretKey secretKey = keyGen.generateKey();
        System.out.println("key: " + Base64.getEncoder().encodeToString(secretKey.getEncoded()));
    }
}

flash cookie值set-cookie：csfcfc = k8auyba％3D;默认情况下是AES加密的。如果未设置jndi键java：comp/env/jsf/jsf/flashsecretkey，则Mojarra将尝试创建一个随机秘密键，该密钥用于flash cookie值中的AES加密中使用。

在群集环境的情况下，该行为将导致每个聚类EAP实例具有不同的秘密密钥。结果，Mojarra无法通过以下错误消息恢复聚类的Flash Cookie值：

20:09:40,317 SEVERE [javax.enterprise.resource.webcontainer.jsf.flash] (default task-1) 
JSF1094: Could not decode flash data from incoming cookie value Invalid characters in decrypted value.  Processing will continue, but the flash is unavailable for this request.

jsf/FlashSecretKey is base64 encoded AES 256bit key which used for encrypting flash scope cookie like csfcfc=K8auYBA%3D;.
The key can generate by the following code:

import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import java.security.NoSuchAlgorithmException;
import java.util.Base64;

public class Main {
    public static void main(String ... args) throws NoSuchAlgorithmException {
        KeyGenerator keyGen = KeyGenerator.getInstance("AES");
        keyGen.init(256); // key length is 256 byte
        SecretKey secretKey = keyGen.generateKey();
        System.out.println("key: " + Base64.getEncoder().encodeToString(secretKey.getEncoded()));
    }
}

The flash cookie value Set-Cookie: csfcfc=K8auYBA%3D; is AES encrypted by default. If JNDI key java:comp/env/jsf/FlashSecretKey is not set, Mojarra will try to create a random secret key that is used in AES encryption for the flash cookie value.

In case of cluster environment, that behavior will cause each clustered EAP instance has a different secret key. As a result, Mojarra is unable to restore clustered flash cookie value with the following error message:

20:09:40,317 SEVERE [javax.enterprise.resource.webcontainer.jsf.flash] (default task-1) 
JSF1094: Could not decode flash data from incoming cookie value Invalid characters in decrypted value.  Processing will continue, but the flash is unavailable for this request.
