Assuming my current package structure in a spring projects as :
com.stackoverflow
|- service
|- entities
|- controllers
|- package1
|- package2
|-util
How can I apply an aspect to all the packages under com.stackoverflow except on the package util?
Applying it to everything, the execution expression would be "com.stackoverflow...(..)"
What should the execution expression be in this case I want to remove the util subpackage from the execution expression?

Executing method on the target class Thus, Spring AOP injects a proxy instead of an actual instance of the target class. When we start the Spring or Spring Boot application, we see Spring executes the advice before the actual method.
Pointcut is a set of one or more JoinPoint where an advice should be executed. You can specify Pointcuts using expressions or patterns as we will see in our AOP examples. In Spring, Pointcut helps to use specific JoinPoints to apply the advice.
In Spring AOP, aspects are implemented using regular classes (the schema-based approach) or regular classes annotated with the @Aspect annotation (the @AspectJ style). Join point: a point during the execution of a program, such as the execution of a method or the handling of an exception.
Around advice can perform custom behavior before and after the method invocation. It is also responsible for choosing whether to proceed to the join point or to shortcut the advised method execution by returning its own return value or throwing an exception.
Use the AND && and NOT ! operators in your Pointcut expression as
@Pointcut ("execution (* com.stackoverflow..*.*(..)) && " +
"!execution (* com.stackoverflow.util..*.*(..))")
