Regexpmethodpointcutadvisor: Regular method Entry-point consultant

Core:

<property name= "pattern" value= ". *do.*" ></property> means full name (package name, interface name, method name)
Operator name meaning
. The dot number represents any single character
+ PLUS sign indicates one or more occurrences of the previous character
* Asterisks indicate that the previous character appears 0 or more times

Specific Use cases:

A class that implements two methods: Someserviceimpl

Package Cn.dawn.day16advisor02;/** * Created by Dawn on 2018/3/8.*/ Public classSomeserviceimpl { Public voidDosome () {System. out. println ("Do something"); }     Public voidDoany () {System. out. println (" Do any"); }}

A way to implement an arbitrarily enhanced interface: Here is the post-enhancement, I named Loggerafter

Package Cn.dawn.day16advisor02;import Org.springframework.aop.afterreturningadvice;import Java.lang.reflect.Method;/** * Created by Dawn on 2018/3/5.*//*Post Enhancement*/ Public classLoggerafter implements Afterreturningadvice { Public voidafterreturning (Object o, Method, object[] objects, Object O1) throws Throwable {System. out. println ("===============after=================="); }}
