Get method arguments using Spring AOP?

Question

I am using Spring AOP and have below aspect:

@Aspect
public class LoggingAspect {

    @Before(\"execution(* com.mkyong.customer.bo.CustomerBo.addCustomer(..         


        

Answer 1

if your using @Aspect an option is add this method inside your Aspect and send the JoinPoint and the name of parameter you need.

private Object getParameter(ProceedingJoinPoint joinPoint, String parameterName) {
    Object valueParameter = null;
    if (Objects.nonNull(joinPoint) && joinPoint.getSignature() instanceof MethodSignature
            && Objects.nonNull(parameterName) ) {
        MethodSignature method = (MethodSignature)joinPoint.getSignature();
        String[] parameters = method.getParameterNames();
        for (int t = 0; t< parameters.length; t++) {
            if( Objects.nonNull(parameters[t]) && parameters[t].equals(parameterName)) {
                Object[] obj = joinPoint.getArgs();
                valueParameter = obj[t];
            }
        }
    }
    return valueParameter;
}

and the call example:

Object parameterObject = getParameter(joinPoint, "nameClient");
if ( Objects.nonNull(parameterObject) ) {
    String parametro = String.valueOf(parameterObject);
}

Only need know the type of object for convert
