ajax - Spring Remember Me 身份验证后 JSF/Primefaces Ajax 请求的 ViewExpiredException

Question

我对 Primefaces 和客户端 View 状态有疑问

<context-param>
    <param-name>javax.faces.STATE_SAVING_METHOD</param-name>
    <param-value>client</param-value>
</context-param>

当尝试恢复 AJAX 请求的 View 时，我收到 ViewExpiredException。目前，仅当通过 Spring RememberMe 执行身份验证时才会发生这种情况，并且仅适用于 AJAX 请求，如果页面完全重新加载，则不会。

一些分析:

系统尝试恢复 View

com.sun.faces.renderkit.ClientSideStateHelper.doGetState(String stateString)

然后调用

com.sun.faces.renderkit.ByteArrayGuard.decrypt(byte[] bytes)

这里是方法

 Arrays.equals(macBytes, macBytesCalculated)

失败并出现错误

ERROR: MAC did not verify!

被触发，这会阻止 View 恢复。我猜想这与 AJAX 请求的给定内容和 ByteArrayGuard 中的解密之间的加密逻辑不同有关。

我还测试了 https://java.net/jira/browse/JAVASERVERFACES-2553 中提供的最新版本然而，它并没有改变行为。 (与 JAVASERVERFACES-2553 相反，我的问题与线程安全无关......)

有什么想法吗？

谢谢并亲切的问候，克里斯

我的想法是正确的，这个问题可以通过修补 com.sun.faces.renderkit.ByteArrayGuard 中的 setupKeyAndMac() 方法来解决，从而防止在服务器启动时生成新的随 secret 钥:

private void setupKeyAndMac() {

try {
    // caution, use exact this length!
    String secret = "1256325896545822129522";
    sk = new SecretKeySpec(new Base64().decode(secret.getBytes()), "AES");
    // KeyGenerator kg = KeyGenerator.getInstance(KEY_ALGORITHM);
    // kg.init(KEY_LENGTH); // 256 if you're using the Unlimited Policy Files
    // sk = kg.generateKey();

} catch (Exception e) {
    throw new FacesException(e);
}
}

参见http://svn.apache.org/repos/asf/myfaces/shared/trunk/core/src/main/java/org/apache/myfaces/shared/util/StateUtils.java获取实现引用，可以在 web.xml 中配置静态 MAC key 。
