Why tomcat throw NullPointException when I use pointcut for args()? - spring-boot

Question

I try to use AspectJ pointcut for args(), but run in springboot with tomcat it threws NullPointException.
Since it reported a null pointer exception, and I debugged it when the variable logger of the GenericFilterBean variable is null, I don't know if I need to add extra configuration or what?
I would be grateful if anyone knows how to solve this problem.
error log :

Answer 1

Your pointcut potentially targets the whole world, even Spring framework components. The error message will go away if you limit its scope to what you actually want to intercept, e.g.
#Pointcut("within(cn.piumnl.demo..*) && args(entity)")
The alternative would be to explicitly exclude the packages leading to problems with your pointcut, but I still prefer the white-listing option to this one:
#Pointcut("!within(org.springframework..*) && !within(com.sun..*) && args(entity)")
