报错就在我加入了aop命名空间开始。
为什么会在第一行提示错误呢。错误信息是这样的 
Referenced file contains errors (jar:file:/E:/Users/think/workspace/MyProjSpring/WebContent/WEB-INF/lib/spring.jar!/org/springframework/beans/factory/xml/spring-
 beans-2.5.xsd). For more information, right click on the message in the Problems View and select "Show Details..."

你spring的版本好像是2.5的嘛，把你写的2.0改为2.5
