为什么我在spring中只要添加一段配置就会报jar包冲突的错误？
在application.xml中只要添加&!--
class="org.springframework.jms.listener.DefaultMessageListenerContainer"&
&!-- 事物管理 --&
这段配置就会报

这样的错误，谁能帮助我一下

别慌，仔细看报错内容，说的是没有这个方法错误，也就是说你一加class=‘。。。’‘他找不到，有时候jar版本啥的等原因会造成这种情况
属于剪不清，理还乱的错误，最好的办法是找一个好的配置项目把配置文件考过了就哦了，jar都用调整好的，就是不冲突的意思，网上会有。
或者你就全部删除一个一个添加，看哪个不行，但是效果不好，建议前者，希望对你有用！加油
其他相似问题使用Spring进行web开发时，第一步就是导入jar包，今天使用SPring Task开发定时器时，导入了好多次jar包，都是报错，不知道是因为jar包版本不同还是因为需要依赖的jar包没加入，反正就是怎么着都不行。
后来终于找着全的了。
首先记录一下spring jar包报错的常见bug：
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'org.springframework.context.annotation.internalAsyncAnnotationProcessor': Initializ nested exception is java.lang.NoClassDefFoundError: org/aopalliance/aop/Advice
目测这个bug感觉像spring aop的jar包没导入，但实际上是已经导过的。最后才知道是因为aopalliance的jar包没导入才抛出这个错误的，这个包应该是aop依赖的吧。
现在没时间仔细研究，先记录下来，下次整明白。
附，定时器开发需要的jar包目录：
