希望你做得好！
目前我正在尝试将我的Web应用程序迁移到无服务器架构。 但现在我面临有关SAML集成的问题。
以前我的applicationcontext.xml文件是在web.xml中加载的
`
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/securityContext.xml
</param-value>
</context-param> <listener>
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>
`
但现在由于它没有任何服务器和web.xml文件，我尝试在我的应用程序的入口点使用java配置加载相同的内容。但是它给出了如下错误。
`Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.filterChains': Cannot resolve reference to bean 'org.springframework.security.web.DefaultSecurityFilterChain#5' while setting bean property 'sourceList' with key [5]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.web.DefaultSecurityFilterChain#5': Cannot resolve reference to bean 'metadataGeneratorFilter' while setting constructor argument with key [0]; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'metadataGeneratorFilter' defined in class path resource [securityContext.xml]: Cannot create inner bean 'org.springframework.security.saml.metadata.MetadataGenerator#28f3b248' of type [org.springframework.security.saml.metadata.MetadataGenerator] while setting constructor argument; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.security.saml.metadata.MetadataGenerator#28f3b248': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.security.saml.metadata.MetadataGenerator.setSamlWebSSOFilter(org.springframework.security.saml.SAMLProcessingFilter); nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'samlWebSSOProcessingFilter': Injection of autowired dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Could not autowire method: public void org.springframework.security.saml.SAMLProcessingFilter.setContextProvider(org.springframework.security.saml.context.SAMLContextProvider); nested exception is org.springframework.beans.factory.NoSuchBeanDefinitionException: No matching bean of type [org.springframework.security.saml.context.SAMLContextProvider] found for dependency: expected at least 1 bean which qualifies as autowire candidate for this dependency.

请指导我如何加载它。
