Question

我刚刚创建了一个简单的Java项目，当我从intellji运行the时，它运行良好，但是当我转换为jar文件并运行时，却出现如下错误：（当我删除Property'includeEventTypes时，它可以正常运行罐子！）

Bean 'ignite.cfg'; nested exception is org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/util]

pom.xml和config.xml中没有验证错误，
