Question

当我尝试在Tomcat 6上运行应用程序时，我遇到了一些Spring 3.1 Namespace问题：

GRAVE: Exception sending context initialized event to listener instance of class org.springframework.web.context.ContextLoaderListener
org.springframework.beans.factory.parsing.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]

所有JAR都在 WEB-INF / lib 下，XML配置在 WEB-INF 下。有什么想法吗？

提前感谢，André

Answer 1

看起来像是一个lib问题。打开战争，搜索是否存在任何spring-tx jar。如果它存在且没有重复项，请打开jar并移至org.springframework.transaction.config并查看spring-tx-3.1.xsd是否存在。这是Spring从中加载模式的地方。如果你找不到jar，它就没有进入你的类路径 - 检查.classpath文件。另请注意以前版本的重复项。
