今天在开发中，碰到一下类似的错误信息：

好奇怪的问题呀……

问题的分析

其中的关键信息是：

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Cannot locate BeanDefinitionParser for element [listener]
Offending resource: class path resource [spring-config-jmq.xml]

从上述错误信息分析，可知问题在spring-config-jmq.xml文件中，这个是非常明显的。错误的问题是在解析Bean的时候出现的BeanDefinitionParsingException，原因是Confgiuration错误，元素错误，其中的一个元素是listener。
结合这个错误信息可知，listener这个节点在与某个Bean的解析中，发生了问题，至于是什么问题，需要结合配置文件来分析。
查看之后发现：

<jmq:listener topic="aifashion_producer" listener="consumertest" />
.......................
<jmq:consumer id="consumer" transport="jmq.transport" longPull="10000" pullTimeout="11000" autoStart="true">
<jmq:listener topic="@sys.jmq.product.topic.price@" listener="productPriceListener" maxConcurrent="10" minConcurrent="1" />
</jmq:consumer>

在上述配置中，可以发现listener节点竟然没有放在jmq:consumer节点中，所以导致了此问题的发生。真是汗颜呀，纯粹声明的时候晕了头……

总结

低级错误一个，但是基于异常信息来分析得出问题的大致根源和方向是最有价值的一件事情。
