在我的 Vaadin 应用程序项目中，我想集成 spring-security-SAML 扩展。我从 spring 安全扩展页面下载了源代码。根据手册，我使用 mvn package 打包了扩展，并使用 mvn deploy 命令将其部署在本地 maven 存储库中。一切顺利。已编译的扩展出现在 Maven 存储库中。所以我将它作为依赖项包含在项目 pom.xml 文件中，如下所示：
<dependency>
<groupId>org.springframework.security.extensions</groupId>
<artifactId>spring-security-saml2-core</artifactId>
<version>1.0.0-RC1-SNAPSHOT</version>
</dependency>
之后我更新了 maven 项目并在 maven 依赖目录中找到了 spring-security-saml2-core-1.0.0-RC1-SNAPSHOT.jar（我正在使用 Maven 的 Eclipse IDE）。我做的下一件事是编辑appLicationContext.xml文件。applicationContext.xml文件包含在 web.xml 中。所以我在appLicationContext.xml文件中添加了以下几行：
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:security="http://www.springframework.org/schema/security"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">

</security:http>
<security:authentication-manager alias="authenticationManager">
<security:authentication-provider ref="samlAuthenticationProvider"/>
</security:authentication-manager>
<bean id="samlAuthenticationProvider" class="org.springframework.security.saml.SAMLAuthenticationProvider">
</bean>
<bean id="samlEntryPoint" class="org.springframework.security.saml.SAMLEntryPoint">

</bean>
</property>
</bean>
<bean id="metadataGeneratorFilter" class="org.springframework.security.saml.metadata.MetadataGeneratorFilter">
<constructor-arg>
<bean class="org.springframework.security.saml.metadata.MetadataGenerator"/>
</constructor-arg>
</bean>
在对文件进行此类更改后，我将我的项目编译为战争存档并尝试将其上传到 glassfish 服务器。但后来我得到一个错误：
Error occurred during deployment: Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: org.springframework.beans.factory.BeanCreationException:
Error creating bean with name 'org.springframework.security.authentication.ProviderManager#0':

我发现了几个具有此类问题的主题，但库不同。没有人可以帮助我解决我的问题。看起来 org.springframework.security.saml.SAMLAuthenticationProvider 无法在战争档案中找到或解决。但是我手动查了一下，在WEB-INF/lib文件夹spring-security-saml2-core-1.0.0-RC1-SNAPSHOT.jar找到了。我还检查了 jar 存档并找到了 SAMLAuthenticationProvider.class。有谁可以帮我解决我的问题。也许有人对 Spring 安全性和 saml 扩展有经验。
