ssm整合时出现 org.springframework.beans.factory.BeanCreationException ：Error creating bean with name ‘XXX’ 异常的原因及解决方法

ssm整合时出现 org.springframework.beans.factory.BeanCreationException ：Error creating bean with name ‘XXX’ 异常的原因及解决方法（只是可能出现下列几种，不包含全部）

此异常为：注入 bean 失败异常，也就是找不到注入的bean。

可能有以下几种原因：

  1.bean未注解或者注解错误

  2.项目整合的时候jar包冲突

  3.‘XXX’的配置有错误

解决：1,3仔细检查就是，网上大部分的人应该是2这种错误，我应该也是这种错误，但不知道哪些jar包冲突了，最简单的解决办法直接把别人的pom.xml拿过来用就是(天才的解决办法)
