问题定位：execution表达式配置错误，缺少返回类型，补上login方法的返回类型String，问题解决
<aop:config> <aop:pointcut expression="execution(String com.wulinfeng.test.testpilling.service.TestPillingService.login(..))" id="pointCut" /> <aop:advisor advice-ref="advice" pointcut-ref="pointCut" /> <aop:aspect></aop:aspect> </aop:config>
我们看下这个execution表达式：
1、execution()是表达式主体，里面是切点匹配的通配符表达式；
2、execution(后面紧跟方法返回类型，我这里指定了具体方法login，所以可以指定具体返回类型为String，如果匹配多个，最好用星号*；
3、全路径类名表达式，支持包名通，如：
"execution(* com.wulinfeng.*.testpilling.service.TestPillingService.login(..))"
支持类名通配，如：
"execution(* com.wulinfeng.*.testpilling.service.*Service.login(..))"
也支持方法名通配，如：
"execution(* com.wulinfeng.*.testpilling.service.*Service.*(..))"
方法的参数也支持通配，如上面就是支持任意参数。最后看下类名前面的多加的一个点：
"execution(* com.wulinfeng.*.testpilling.service..*Service.*(..))"
表示当前包及子包。注意返回类型跟全路径类名之间有个空格。
