【问题描述】：
我的任务是将 Spring Data 库，特别是它的 spring Repository 实现合并到使用 Ant 和 Java 1.6 构建的遗留 Java Web 应用程序中。我收到有关与 Spring Data JPA 命名空间（下面的堆栈跟踪）相关的“RepositoryConfigurationExtension”的错误。我使用了以下库依赖项：
<pathelement location="${compile.lib}/spring-core-4.2.9.RELEASE.jar"/>
<pathelement location="${compile.lib}/spring-data-commons-1.12.10.RELEASE.jar"/>
<pathelement location="${compile.lib}/spring-orm-4.2.9.RELEASE.jar"/>
<pathelement location="${compile.lib}/spring-aop-4.2.9.RELEASE.jar"/>
<pathelement location="${compile.lib}/spring-aspects-4.2.9.RELEASE.jar"/>
<pathelement location="${compile.lib}/spring-jdbc-4.2.9.RELEASE.jar"/>
<pathelement location="${compile.lib}/spring-beans-4.2.9.RELEASE.jar"/>
<pathelement location="${compile.lib}/spring-data-jpa-1.10.10.RELEASE.jar"/>
然后我在以下 xml 文件中配置了存储库：
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:jpa="http://www.springframework.org/schema/data/jpa"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/data/jpa
http://www.springframework.org/schema/data/jpa/spring-jpa.xsd">
<context:component-scan base-package="com.cc.spring.beans.persistence, com.cc.spring.beans.persistence.repository"/>
<jpa:repositories base-package="com.cc.spring.beans.persistence.repository"/>
</beans>
这是我收到的堆栈跟踪：
org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/spring/beans/cycpersistence-beans.xml]; nested exception is org.springframework.beans.FatalBeanException: Invalid NamespaceHandler class [org.springframework.data.jpa.repository.config.JpaRepositoryNameSpaceHandler] for namespace [http://www.springframework.org/schema/data/jpa]: problem with handler class file or dependent class; nested exception is java.lang.NoClassDefFoundError: org/springframework/data/repository/config/RepositoryConfigurationExtension

有什么想法吗？我错过了什么吗？我无法摆脱这个错误并继续实际测试 Spring Repositories 的合并。在这一点上，我愿意尝试任何事情。提前谢谢！
P.S - 我查看了类似的 Stack Overflow 问题，例如 getting error Invalid NamespaceHandler class org.springframework.data.jpa.repository.config.JpaRepositoryNameSpaceHandler 并遵循了他们的建议。不幸的是，它没有用，这就是我发布自己的问题的原因。
为了回应 Neil 并提供对问题的更多见解，我附上了 jar 文件中类的屏幕截图，并确认它在类路径中。
【问题讨论】：
-
缺少的类
RepositoryConfigurationExtension应该包含在spring-data-commons-1.12.10.RELEASE.jar中。您能否验证此 jar 在运行时是否位于类路径中，例如通过打印出类路径？另外，请确认 jar 确实包含此类。 -
Jens，您能否将此作为单独的答案发布，以便我将正确答案归功于您？编译类路径是正确的，但不是运行时类路径。这是我第一次使用 Jboss，我没有意识到 Ant 构建文件没有复制必要的 .jar 文件。存储库配置扩展错误不再存在:)
