Extraction of the same pointcut

1. Extraction of the same entry point

Before extraction ：

package com.spring.spring5.annotaion;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.stereotype.Component;

// Enhanced classes 
@Aspect// Represents the generation of proxy objects 
@Component
public class UserProxy {
    

    // Pre notice 
    @Before(value = "execution(* com.spring.spring5.annotaion.User.add(..))")// As a pre notification 
    public void before(){
    
        System.out.println("Before......");
    }

    // Final notice , Execute after the method with or without exceptions 
    @After(value = "execution(* com.spring.spring5.annotaion.User.add(..))")
    public void after(){
    
        System.out.println("After......");
    }

    // The rear notice （ Return to inform ）, Execute when the method ends without exception 
    @AfterReturning(value = "execution(* com.spring.spring5.annotaion.User.add(..))")
    public void afterReturning(){
    
        System.out.println("AfterReturning......");
    }

    // Abnormal notice ,add() Only when there are exceptions 
    @AfterThrowing(value = "execution(* com.spring.spring5.annotaion.User.add(..))")
    public void afterThrowing(){
    
        System.out.println("AfterThrowing......");
    }

    // Surrounding the notification , Execute before and after method 
    @Around("execution(* com.spring.spring5.annotaion.User.add(..))")
    public void around(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {
    
        System.out.println("Around Before ......");
        proceedingJoinPoint.proceed();
        System.out.println("Around after ......");
    }
}

After extraction ：

package com.spring.spring5.annotaion;

import org.aspectj.lang.ProceedingJoinPoint;
import org.aspectj.lang.annotation.*;
import org.springframework.stereotype.Component;

// Enhanced classes 
@Aspect// Represents the generation of proxy objects 
@Component
public class UserProxy {
    
    // Extracting the same entry point 
    @Pointcut("execution(* com.spring.spring5.annotaion.User.add(..))")
    public void pointdemo() {
    

    }

    // Pre notice 
    @Before(value = "pointdemo()")// As a pre notification 
    public void before(){
    
        System.out.println("Before......");
    }

    // Final notice , Execute after the method with or without exceptions 
    @After(value = "pointdemo()")
    public void after(){
    
        System.out.println("After......");
    }

    // The rear notice （ Return to inform ）, Execute when the method ends without exception 
    @AfterReturning(value = "pointdemo()")
    public void afterReturning(){
    
        System.out.println("AfterReturning......");
    }

    // Abnormal notice ,add() Only when there are exceptions 
    @AfterThrowing(value = "pointdemo()")
    public void afterThrowing(){
    
        System.out.println("AfterThrowing......");
    }

    // Surrounding the notification , Execute before and after method 
    @Around("pointdemo()")
    public void around(ProceedingJoinPoint proceedingJoinPoint) throws Throwable {
    
        System.out.println("Around Before ......");
        proceedingJoinPoint.proceed();
        System.out.println("Around after ......");
    }
}

The two have the same effect
