org.springframework.beans.factory.BeanDefinitionStoreException 与at org.springframework.asm.ClassRead

一、前言

       这是一个关于SpringMVC报出的异常。之所以写这篇文章，因为被这个问题弄了快4个小时。最后总算是解决了。所以干脆就直接把这个恶心的错误给写出来，免得第二天没时间写。也让大家可以参考参考这个错误。

二、内容

          废话不多说，先贴出我的代码。和出现的异常

首先我在运行我所写的SpringMVC小例子(如何理解注解映射器)的时候。出现了上面的错误。我首先按照往常的方法找异常。看错误报在ItemsController3.class上。我就找源文件的。一个个的看，没发现错误。我猜问题肯定出在我配置的springmvc.xml上。然后就一个个的看配置。把流程走了一遍又一遍。重启tomcat服务器也重启了十几遍。硬是找不大错误。然后我就开始不采用注解的方式。结果成功了。我就好奇了，为什么注解就不能成功。采用非注解的方式就成功。然后把自动扫包去掉，自己写了个bean，结果成功了。最后我肯定问题出现在扫包上面。然后开始怀疑是不是版本有问题。会不会是冲突或是怎么滴。然后自己重新下包试了一下。果然如此。

我用的springmvc的jar包是3.2的。而我的jdk是1.8的。然后我改用springmvc的jar包为4.1.6。然后成功了。哈哈。终于把问题解决了。我想3.2的估计只能用1.7的jdk。我懒得重装JDK了。就不试了。

三、结论

       版本冲突  

       1.7jdk -----3.2的springmvc  jar包   

        1.8jdk -----4.1.6 的springmvc  jar包
