找不到 XML 模式命名空间的 Spring NamespaceHandler (spring-context.xml)

Question

当我在 Eclipse 中的 Tomcat 服务器上启动我的 Web 应用程序时，我收到以下错误消息。

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/aop]
Offending resource: class path resource [spring-context.xml]

我猜spring-context.xml 文件的这一部分配置错误。我正在将一个 Web 应用程序从 Spring 2.5 升级到 Spring 3.0。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

    ...
</beans>

我将com.springsource.org.aopalliance-1.0.0.jar 库添加到类路径中。

我该如何解决这个问题？谢谢！

我通过添加 org.springframework.aop-3.0.0.RELEASE.jar 库解决了这个问题。
