Spring Security SAML扩展配置错误：“无法实例化[org.springframework.security.saml.SAMLBootstrap]”

Question

我正在开发一个使用Spring Security SAML扩展的Spring应用程序。这些是我在项目pom.xml中的依赖项：

使用Maven构建它时，我没有任何错误，但是当我将WAR部署到Tomcat时，它给了我以下错误：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.saml.SAMLBootstrap#0' defined in ServletContext resource [/WEB-INF/applicationContext-security.xml]: Instantiation of bean failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.springframework.security.saml.SAMLBootstrap]: No default constructor found; nested exception is java.lang.NoClassDefFoundError: org/opensaml/xml/ConfigurationException

我已经尝试寻找可能缺少的依赖项，但是我对如何做感到茫然。

编辑：我尝试为org.opensaml xmltooling添加一个依赖项，但是出现了相同的错误。
