Spring aop Pointcut is not well-formed

问题

<aop:config>
    <aop:pointcut expression="exection(* info.fdlife.service.UserService.*(..))"
        id="aopProductUserService" />
    <aop:advisor advice-ref="txAdvice" pointcut-ref="aopProductUserService" />
</aop:config>

Here is some of applicationContext.xml (Spring Framework), info.fdlife.service.UserService is a interface. I get some error message:

Caused by: java.lang.IllegalArgumentException: Pointcut is not well-formed: expecting ')' at character position 11 exection(* info.fdlife.service.UserService.*(..))

What does this mean?
