Caused by: java.lang.IllegalArgumentException: error at ::0 formal unbound in pointcut

Question

I've checked other SO questions like this but none seem to apply.

I have my Service class:

package com.test.demo.service;

import com.test.demo.controller.Controller2;
import com.test.demo.model.SettlementTransaction;
import org.springframework.stereotype.Service;

@Service
public class TestService {

    public Controller2.AcctDetails testAcctDeets(Transaction transaction){

and my aspect:

@AfterReturning(pointcut = "execution(* com.test.demo.service.TestService.testAcctDeets(..))", returning = "response")
public void interceptRequest(Controller2.AcctDetails response, JoinPoint thisJoinPoint) {
    System.out.println(thisJoinPoint);
    for (Object arg : thisJoinPoint.getArgs()) {
        if (arg instanceof String)
            System.out.println("  request = " + arg);
    }
    System.out.println("  response = " + response.toString());
}

but I keep getting the error:

Caused by: java.lang.IllegalArgumentException: error at ::0 formal unbound in pointcut

Any help is appreciated. Thank you!

Answer 1

From the reference documentation : Access to the Current

Any advice method may declare, as its first parameter, a parameter of type org.aspectj.lang.JoinPoint (note that around advice is required to declare a first parameter of type ProceedingJoinPoint, which is a subclass of JoinPoint

This is documented as continuation to the topic Advice Parameters which has reference to this : Spring offers fully typed advice, meaning that you declare the parameters you need in the advice signature (as we saw earlier for the returning and throwing examples).

When read together , when passing advice parameters and the advice method also has JointPoint or any of its subclas as another parameter , the latter should be declared as the first parameter.

So in this case , the valid method signature would be

@AfterReturning(pointcut = "execution(* com.test.demo.service.TestService.testAcctDeets(..))", returning = "response")
public void interceptRequest(JoinPoint thisJoinPoint, Controller2.AcctDetails response) {
    // ..
}
