Question

我在Spring项目上遇到以下异常。即使我尝试了stackoverflow中提出的几个解决方案，我还无法解决。你能帮我吗？

java.lang.Exception：java.lang.IllegalStateException：ContainerBase.addChild：start：org.apache.catalina.LifecycleException：org.springframework.beans.factory.parsing.BeanDefinitionParsingException：配置问题：无法找到命名空间的NamespaceHandler [http://www.springframework.org/schema/context] 违规资源：类路径资源[springDAO.xml]

Answer 1

我下载了activemq-core-5.0-SNAPSHOT pom.xml。它使用Spring 2.0.6作为依赖项。我看到你有Spring 2.5.6 SEC02作为你的spring依赖。

根据activeMQ pom文件，我相信你必须使用spring 2.0.6作为依赖，而不是2.5.6？

至于您的命名空间未解析的实际问题，通常是类路径中不存在依赖关系的问题。在这种情况下，因为活动的mq使用Spring 2.0.6，所以它不在类路径中。

无法找到命名空间的NamespaceHandler（http://www.springframework.org/schema/context）
