    @Pointcut("execution(* springdemo2."
            + "Thinker.thinkOfSomething(String)) and args(thoughts)")
    public void thinking(String thoughts){
    }

    @Override
    @Before("thinking(thoughts)")
    public void interceptThoughts(String thoughts) {
        this.thoughts=thoughts;
        System.out.println("Advice method intercepted Thoughts..."+thoughts);

@Pointcut("execution(* springdemo2."
    + "Thinker.thinkOfSomething(String)) and args(thoughts)")

should be

@Pointcut("execution(* springdemo2."
    + "Thinker.thinkOfSomething()) && args(thoughts)")

I just can't believe it! the 'and' operator is valid in xml configuration but not in the annotated version. Thanks!

@Before("thinking(thoughts)")

should be

@Before("thinking(String) && args(thoughts)")

Don't use "and" operator to link aspect designators. In Java you can use the "&&" operator. "and" is only available in XML.

However, if the parameters of each method are not the same, how to do？

I'll tell you:

Spring uses the Annotation annotation using the Joinpoint interface declaration in aopalliance.jar:org.aopalliance.intercept.Joinpoint.

The xml configuration is used Joinjoint.jar Join statement:org.aspectj.lang.JoinPoint.

So, you should use aspectj's JoinPoint in method.

This answer could probably do with some inline formatting or block formatting to make it more readable. Don't forget that case and spelling are important too.

Whenever java.lang.IllegalArgumentException : error at ::0 formal unbound in pointcut like problem occur then kindly check the structure of your advice, or expression of pointcut in maximum cases error will be there itself.
