我正在尝试一个例子。在示例中，它被提及为使用 spring-integration 2.0.3，但我得到了 NullPointerExcpetion 并且为了解决它，我遵循了这里提到的内容。但是如果我使用 spring-integration 2.1，那么我认为它需要 spring 3.0。
问题： 是否有可能拥有 Spring 2.5 版并使用从 imap 读取电子邮件的 spring-integration？
以下是我项目中设置的maven依赖：

如果我运行我的测试用例，我会收到以下异常：
org.springframework.beans.factory.BeanDefinitionStoreException：从类路径资源 [META-INF/spring/component.xml] 解析 XML 文档时出现意外异常；嵌套异常是 org.springframework.beans.factory.xml.XmlBeanDefinitionReader.doLoadBeanDefinitions(XmlBeanDefinitionReader.java:420) 中的 java.lang.NoClassDefFoundError: org/springframework/scheduling/support/PeriodicTrigger。 XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:342) at org.springframework.beans.factory.xml.XmlBeanDefinitionReader.loadBeanDefinitions(XmlBeanDefinitionReader.java:310) at org.springframework.beans.factory.support.AbstractBeanDefinitionReader.loadBeanDefinitions(AbstractBeanDefinitionReader.java: 143）在 org.springframework.beans.factory.support.AbstractBeanDefinitionReader。
