Maven的组装插件错误

Question

maven-assembly插件导出和名为escomled-machine-learning-0.0.1-SNAPSHOT-jar-with-dependencies.jar可执行jar。 但是当我尝试运行jar时，它给了我一个例外：

线程“主”中的异常org.springframework.beans.factory.parsing.BeanDefinitionParsingException：配置问题：无法为XML模式命名空间找到Spring NamespaceHandler [ http://www.springframework.org/schema/context]令人讨厌的资源：类路径资源[appContext.xml]

注意：我尝试使用maven-shade插件，但是没有成功。

您的Maven程序集插件不是问题，而是Spring配置。 检查您的xml文件，并在乞求中查找标记中包含的名称空间。 这样的事情。 同时检查是否有所有的弹簧罐
