创建名称为 org.springframework.security.saml.metadata.ExtendedMetadataDelegate 的 bean 时出错：无法解析匹配的构造函数

Question

我必须为客户集成 Shibboleth SP 身份验证，我需要将它与我在 JBoss AS 7 上的 J2EE 应用程序（JSF2、EJB3、JPA2）集成。
我正在使用这个库：

spring-security-core-3.2.5 和依赖项
spring-security-saml2-core-1.0.0 和依赖项
spring 框架 4.1.3

目前有一个实现 JdbcDaoImpl 用于身份验证和授权的 bean。我已成功部署 Spring SAML 示例应用程序，但无法将其集成到我的应用程序中。我在部署期间收到异常，似乎无法构造 ExtendedMetadataDelegate bean，其定义如下：

<beans:bean id="metadata" class="org.springframework.security.saml.metadata.CachingMetadataManager">
    <beans:constructor-arg>
        <beans:list>
            <!-- Example of classpath metadata with Extended Metadata -->
            <beans:bean class="org.springframework.security.saml.metadata.ExtendedMetadataDelegate">
                <beans:constructor-arg>
                    <beans:bean class="org.opensaml.saml2.metadata.provider.ResourceBackedMetadataProvider">
                        <beans:constructor-arg>
                            <beans:bean class="java.util.Timer"/>
                        </beans:constructor-arg>
                        <beans:constructor-arg>
                            <beans:bean class="org.opensaml.util.resource.ClasspathResource">
                                <beans:constructor-arg value="/CustomerIDPMetadata.xml"/>
                            </beans:bean>

                    </beans:bean>

            </beans:bean>
            <!-- Example of HTTP metadata without Extended Metadata -->

                <!-- URL containing the metadata -->

                <!-- Timeout for metadata loading in ms -->
                <beans:constructor-arg>
                    <beans:value type="int">15000</beans:value>
                </beans:constructor-arg>

                </constructor-arg>
                <property name="parserPool" ref="parserPool"/>
            </bean>
            -->
        </beans:list>
    </beans:constructor-arg>
    <!-- OPTIONAL used when one of the metadata files contains information about this service provider -->
    <!-- <property name="hostedSPName" value=""/> -->
    <!-- OPTIONAL property: can tell the system which IDP should be used for authenticating user by default. -->
    <!-- <property name="defaultIDP" value="http://localhost:8080/opensso"/> -->
</beans:bean>

ExtendedMetadataDelegate 构造函数采用 MetadataProvider 和 ExtendedMetadata，这部分配置似乎是正确的。
有什么想法吗？

已解决。在 Eclipse 中，我在部署部分为 Web 项目指定导出所有 spring-saml-sample jar。
