Question

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。我知道它仍然在RC中，但我们正在开发的应用程序也是如此。我们在部署到Tomcat7时集成了库并且功能完备，但在部署到Weblogic 12c（12.0.1.2）时遇到了问题。在Weblogic上没有抛出任何错误，断言值将被解释为空无错误。

问题似乎出现在Xerces库中。 Spring SAML（由于OpenSAML）需要2.10.0，据我所知，但Weblogic提供了2.8.0的Xerces库。我试图通过在xercesImpl和xml-apis中包含适当的xercesImpl和xml-apis来更新Xerces库版本。项目WEB-INF / lib文件夹。这解决了Spring SAML的decrpyting问题，但破坏了Weblogics解析JSP页面的能力。我已经为下面的非升级和升级的Xerces异常包含了部分堆栈跟踪。如果有人知道如何正确解决这个问题，以便Spring SAML可以在不破坏默认功能的情况下运行Weblogic，我将非常感激。

这是更新Xerces之前的堆栈跟踪

Answer 1

对于后来遇到此事的人。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要求它解决问题的要少，而不会引起Weblogic的任何其他问题（据我目前遇到）。 Xerces 2.10.0需要xml-apis的更新版本才能运行，这导致了Weblogic的问题（2.9.0似乎与Weblogic中包含的xml-apis版本一起使用）。

Answer 2

以下方法允许在Weblogic中捆绑自定义Xerces和Xalan库：

创建ear archive spring-security-saml2-sample.ear
将Spring SAML文件spring-security-saml2-sample.war包含在耳内，战争应该包含自己的Xerces和Xalan版本。

使用以下内容在耳内创建文件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"
                      xsi:schemaLocation="http://www.bea.com/ns/weblogic/90 http://www.oracle.com/technology/weblogic/920/weblogic-application.xsd">
    <xml>
        <parser-factory>
            <saxparser-factory>
                org.apache.xerces.jaxp.SAXParserFactoryImpl
            </saxparser-factory>
            <document-builder-factory>
                org.apache.xerces.jaxp.DocumentBuilderFactoryImpl
            </document-builder-factory>
            <transformer-factory>
                org.apache.xalan.processor.TransformerFactoryImpl
            </transformer-factory>
        </parser-factory>
    </xml>
    <prefer-application-packages>
        <package-name>org.opensaml.*</package-name>
        <package-name>org.apache.xerces.*</package-name>
        <package-name>org.apache.xalan.*</package-name>
    </prefer-application-packages>                       
</weblogic-application>

Answer 3

您是使用prefer-web-inf-classes播放战争文件还是prefer-application-packages播放耳文？其中一个可能会解决问题：

在weblogic-application.xml中：

<wls:prefer-application-packages>
    <wls:package-name>org.apache.xerces.xni.parser.*</wls:package-name>
    <wls:package-name>org.apache.xerces.parsers.*</wls:package-name>
    <wls:package-name>org.apache.xalan.*</wls:package-name>
</wls:prefer-application-packages>

在weblogic.xml中：

<wls:container-descriptor>
    <wls:prefer-web-inf-classes>true</prefer-web-inf-classes>
</wls:container-descriptor>
