Java-Weblogic 12c上的Spring SAML

2023-01-04 10:24:01

我目前正在开发一个使用Spring SAML(http://projects.spring.io/spring-security-saml/)项目作为身份验证一部分的应用程序.我知道它仍在RC中,但我们正在开发的应用程序也是如此.部署到Tomcat7时,我们的库已集成并且可以正常运行,但是部署到Weblogic 12c(12.0.1.2)时遇到问题.在Weblogic上,不会抛出任何错误,则断言值将被解密为空且无错误.

问题似乎出在Xerces库中.据我所知,Spring SAML(由于OpenSAML)需要2.10.0,但是Weblogic提供了2.8.0的Xerces库.项目WEB-INF / lib文件夹.这解决了Spring SAML的解密问题,但破坏了Weblogics解析JSP页面的能力.我已经在下面包含了未升级和升级的Xerces异常的部分堆栈跟踪.如果有人对如何正确解决此问题有任何想法,以便Spring SAML可以在不破坏默认功能的情况下正常运行Weblogic,我将不胜感激.

这是更新Xerces之前的堆栈跟踪

这是将Xerces更新为2.10.0之后的堆栈跟踪.

解决方法:

以下方法允许在Weblogic中捆绑自定义Xerces和Xalan库：

>创建耳朵归档文件spring-security-saml2-sample.ear
>在耳朵内包含Spring SAML文件spring-security-saml2-sample.war时,war应该包含自己的Xerces和Xalan版本.
>用以下内容在耳朵内创建文件META-INF / application.xml：

<application xmlns="http://java.sun.com/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/application_5.xsd" version="5">
  <module>
    <web>
      <web-uri>spring-security-saml2-sample.war</web-uri>
      <context-root>spring-security-saml2-sample</context-root>
    </web>
  </module>
</application>

>使用以下内容创建文件META-INF / weblogic-application.xml：

<weblogic-application xmlns="http://www.bea.com/ns/weblogic/90"
                      xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
