Get method arguments using Spring AOP?

by

You have a few options:

First, you can use the JoinPoint#getArgs() method which returns an Object[] containing all the arguments of the advised method. You might have to do some casting depending on what you want to do with them.

Second, you can use the args pointcut expression like so:

// use '..' in the args expression if you have zero or more parameters at that point
@Before("execution(* com.mkyong.customer.bo.CustomerBo.addCustomer(..)) && args(yourString,..)")

then your method can instead be defined as 

public void logBefore(JoinPoint joinPoint, String yourString)
