从ServletContext资源[/WEB-INF/spring-servlet.xml]解析XML文档时出现意外异常;

Question

我创建了一个maven-spring-hibernate项目。 我将项目部署到tomcat服务器。在浏览器中点击URL时，我收到以下异常。

**org.springframework.beans.factory.BeanDefinitionStoreException: Unexpected exception parsing XML document from ServletContext resource [/WEB-INF/spring-servlet.xml]; 

嵌套异常是：

org.springframework.beans.FatalBeanException: Invalid NamespaceHandler class [org.springframework.transaction.config.TxNamespaceHandler] for namespace [http://www.springframework.org/schema/tx]: problem with handler class file or dependent class; nested exception is java.lang.NoClassDefFoundError: Could not initialize class** org.springframework.transaction.config.JtaTransactionManagerBeanDefinitionParser
