我正在尝试运行我的嵌入式 Tomcat 应用程序，但出现以下错误：
BeanDefinitionParsingException:
Configuration problem:
Unable to locate Spring NamespaceHandler for XML schema namespace
[http://www.springframework.org/schema/tx]
Offending resource: ServletContext resource [/WEB-INF/applicationContext.xml]
我非常有信心我的类路径上的所有内容都正确 - 你可以tx看到/transaction/：
$ jar tf webapp.jar | grep 'springframework/[a-z]*/$'
org/springframework/cache/
org/springframework/context/
org/springframework/ejb/
org/springframework/format/
org/springframework/instrument/
org/springframework/jmx/
org/springframework/jndi/
org/springframework/remoting/
org/springframework/scheduling/
org/springframework/scripting/
org/springframework/stereotype/
org/springframework/ui/
org/springframework/validation/
org/springframework/aop/
org/springframework/asm/
org/springframework/beans/
org/springframework/core/
org/springframework/util/
org/springframework/expression/
org/springframework/orm/
org/springframework/jdbc/
org/springframework/dao/
org/springframework/jca/
org/springframework/transaction/
org/springframework/web/
org/springframework/mail/
org/springframework/http/
org/springframework/mock/
我不明白的是，在 Intellij IDEA 中运行应用程序可以按预期工作，并且也可以部署到 Tomcat 服务器。
可能是什么问题？我应该去哪里看？谢谢。
