无法找到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Web应用程序时，出现以下错误消息。

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/aop]

我猜测spring-context.xml文件的这部分配置有误。我正在将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" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"

http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd"> 
    ... 
</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库解决了该问题。
