我正在开发Eclipse/Spring/Maven项目。我的pom.xml看起来是这样的：运行由Maven Assembly插件创建的JAR时出错

我的applicationContext.xml看起来是这样的：

我做mvn install然后mvn package。我在项目的目标目录中得到输出为springexample-0.0.1-SNAPSHOT.jar。然后，我键入命令java - jar springexample-0.0.1-SNAPSHOT.jar并得到以下错误：通过互联网类似的问题
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Config
uration problem: Unable to locate Spring NamespaceHandler for XML schema namespa
ce [http://www.springframework.org/schema/tx]
Offending resource: class path resource [applicationContext.xml]
Browsinf，我发现了错误的两个可能的来源：
- 非指定的春天库名称空间处理（spring-tx） - done（包含在依赖项中） 2.未指定maven程序集插件资源中的applicationContext.xml - done（包含在插件配置中的资源标记）。
之后，我不知道可能是什么问题。任何帮助表示感谢，谢谢。
我面临同样的问题..你能解决这个问题？ @MichalB –
