Document root element "beans", must match DOCTYPE root "null". 原因

有可能是xml使用了schema

 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
 xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-2.5.xsd">



 

 

修改为下面的就好了

  "http://www.springframework.org/dtd/spring-beans.dtd">
