本文介绍了一种在Spring框架中遇到@EnableAsync注解未正确注入元数据的问题，并给出了具体的解决方案。通过调整配置文件中base-package属性的设置，避免了Spring包下的注解被误扫描，从而解决了异常。

异常信息：

整合ssh发现，上面@EnableAsync annotation metadata was not injected的信息，并没有要注入这个东西。上网查，好多人说包冲突，然并卵。然后开始查看自己写的东西，发现在beans.xml下，base-package="*"，这样写应该会将spring包下的注解也扫描，果然将其改成base-package="com.cmr.dao(要扫描的包)"就好了
