Spring security 使用WSO2实现spring saml安全性时出错

我试图实现SAML2.0是我的应用程序，使用我的应用程序作为服务提供商，使用WSO2服务器作为idp。我已经下载并实现了spring-security-saml2-sample应用程序，并对其进行了修改，使其能够作为idp与WSO2服务器一起工作，并且示例应用程序可以按预期工作

我现在尝试将securityContext.xml和相关配置合并到我的应用程序中，但是在元数据生成过程中遇到了一个异常

例外情况如下：

java.lang.IllegalArgumentException: Manager with name 'MetadataKeyInfoGenerator' does not exist
    at org.opensaml.xml.security.keyinfo.NamedKeyInfoGeneratorManager.getFactory(NamedKeyInfoGeneratorManager.java:157)
    at org.opensaml.xml.security.SecurityHelper.getKeyInfoGenerator(SecurityHelper.java:1065)

    at org.springframework.security.saml.metadata.MetadataGeneratorFilter.doFilter(MetadataGeneratorFilter.java:86)
    at org.springframework.security.web.FilterChainProxy$VirtualFilterChain.doFilter(FilterChainProxy.java:342)

我的securityContext.xml元数据配置如下

我没有对示例应用程序securityContext.xml进行任何重大更改。有没有人遇到过类似的错误。任何帮助都将不胜感激

请在下面找到我的整个securityContext.xml

另外，尝试将bean更改为：

<bean class="org.springframework.security.saml.SAMLBootstrap" lazy-init="false"/>

在您的问题中提供完整的
securityContext.xml
将非常有帮助。但首先要确保它包含以下bean，因为异常似乎表明没有执行SAML引导中的初始化登录：

<bean class="org.springframework.security.saml.SAMLBootstrap"/>

<bean class="org.springframework.security.saml.SAMLBootstrap" lazy-init="false"/>

可能对其他人有帮助。我遇到了类似的问题，发生这种情况的原因是系统中的另一段遗留代码正在通过调用
DefaultBootstrap.bootstrap（）重新实例化OpenSAML库

由于SpringSAML已经在容器引导期间对其进行了初始化，因此必须从遗留代码中删除初始化可能对其他代码有所帮助。我遇到了类似的问题，发生这种情况的原因是系统中的另一段遗留代码正在通过调用

我已经用整个securityContext.xml编辑了我的文章。与示例项目的唯一区别是，我不是使用Maven构建的，因此我没有在pom.xml中添加依赖项。相反，我将spring-security-saml2-core-1.0.0.RELEASE.jar和相关的jar添加到我的类路径中。我正在用ant构建我的项目。因此，此异常可能是与类路径相关的问题。我现在试着将我的类路径与示例项目进行比较，看看我是否遗漏了什么。用另一个想法更新了回复。谢谢你的建议！！通过调整示例应用程序生成的元数据，保存元数据，并修改Extendedmetadata bean以从类路径访问sp元数据，我最终实现了它。我现在遇到了签名验证问题。希望我能解决这些问题，然后尝试你的解决方案。我已经用整个securityContext.xml编辑了我的文章。与示例项目的唯一区别是，我不是使用Maven构建的，因此我没有在pom.xml中添加依赖项。相反，我将spring-security-saml2-core-1.0.0.RELEASE.jar和相关的jar添加到我的类路径中。我正在用ant构建我的项目。因此，此异常可能是与类路径相关的问题。我现在试着将我的类路径与示例项目进行比较，看看我是否遗漏了什么。用另一个想法更新了回复。谢谢你的建议！！通过调整示例应用程序生成的元数据，保存元数据，并修改Extendedmetadata bean以从类路径访问sp元数据，我最终实现了它。
