一、问题描述及原因。

       利用Aspect注解实现AOP的时候出现了error at ::0 can't find referenced pointcut XXX。一看我以为注解写错了，结果通过查询相关资料是因为Spring2.5与中的aspectjweaver.jar 和aspectjrt.jar这两个jar包与JDK1.7不匹配。

二、解决办法。

      将aspectjweaver.jar 和aspectjrt.jar这两个jar包的版本升级一下用aspectjweaver-1.7.0 和aspectjrt-1.7.2这两个版本的jar包就可以运行成功.

<<jar包下载>>

三、总结。

       在我们开发中我们得注意jdk与各个jar包版本是否匹配有些时候虽然JDK升级了但是我们所要用的jar并没有适配到更高版本的jdk这时候我们就要降级JDK或者用其他已经适配了最新JDK的jar包。
