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

Your can use either of the following methods.

@Before("execution(* ong.customer.bo.CustomerBo.addCustomer(String))")
public void logBefore1(JoinPoint joinPoint) {
    System.out.println(joinPoint.getArgs()[0]);
 }

or

@Before("execution(* ong.customer.bo.CustomerBo.addCustomer(String)), && args(inputString)")
public void logBefore2(JoinPoint joinPoint, String inputString) {
    System.out.println(inputString);
 }

joinpoint.getArgs() returns object array. Since, input is single string, only one object is returned.

In the second approach, the name should be same in expression and input parameter in the advice method i.e. args(inputString) and public void logBefore2(JoinPoint joinPoint, String inputString)

Here, addCustomer(String) indicates the method with one String input parameter.
