大家好，正在写一个spring的小例子，但是配置文件报错了，在aop:pointcut提示：Description Resource Path Location Type
cvc-complex-type.2.4.a: Invalid content was found starting with element 'aop:pointcut'. One of '{"http://www.springframework.org/schema/aop":aspect}' is expected.
而且<aop:before>和<aop:after>也打不出来，请问大家怎么解决？

<aop:pointcut id="saySome" expression="execution{* *.b3Say(..)}" />

------解决思路----------------------
<aop:aspect> 要写在这个标签里面吧?你写外面去了..
