java - Weblogic 12c 上的 Spring SAML

Question

我目前正在开发一个应用程序，该应用程序使用 Spring SAML ( http://projects.spring.io/spring-security-saml/ ) 项目作为我们身份验证的一部分。我知道它仍在 RC 中，但我们正在开发的应用程序也是如此。当部署到 Tomcat7 时，我们已经集成了库并且功能齐全，但在部署到 Weblogic 12c (12.0.1.2) 时遇到了问题。在不抛出任何错误的 Weblogic 上，断言值将被解密为空无错误。

问题似乎出在 Xerces 库中。据我所知，Spring SAML(由于 OpenSAML)需要 2.10.0，但 Weblogic 提供了 2.8.0 的 Xerces 库。我试图通过在项目 WEB-INF/lib 文件夹。这修复了 Spring SAML 的解密问题，但破坏了 Weblogics 解析 JSP 页面的能力。我在下面包含了未升级和升级的 Xerces 异常的部分堆栈跟踪。如果有人知道如何正确解决此问题，以便 Spring SAML 可以在不破坏默认功能的情况下运行 Weblogic，我将不胜感激。

这是更新 Xerces 之前的堆栈跟踪

这是将 Xerces 更新到 2.10.0 后的堆栈跟踪。

Answer 1

对于以后遇到此问题的任何人。我最终通过更新到 xercesImpl 版本 2.9.0 解决了这个问题。这似乎是这个问题的最佳版本，尽管它比 OpenSAML 要求的要少，但它修复了这个问题，同时不会导致 Weblogic 出现任何其他问题(就我目前遇到的而言)。 Xerces 2.10.0 需要更新版本的 xml-apis 才能运行，这导致了 Weblogic 的问题(2.9.0 似乎可以与 Weblogic 中包含的 xml-apis 版本一起使用)。
