Introduction to Spring - Spring Enterprise Recipes: A Problem Solution Approach - page 58

You can match the method execution join points within all classes that implement the
ArithmeticCalculator interface by adding a plus symbol.
within(ArithmeticCalculator+)

Your custom annotation @LoggingRequired can be applied to the class level instead of the
method level.

package com.apress.springenterpriserecipes.calculator;

@LoggingRequired
public class ArithmeticCalculatorImpl implements ArithmeticCalculator {
...
}

Then you can match the join points within the classes that have been annotated with
@LoggingRequired .
@within(com.apress.springenterpriserecipes.calculator.LoggingRequired)

Bean Name Patterns
Spring supports a new pointcut type that is used to match bean names. For example, the following
pointcut expression matches beans whose name ends with Calculator :

bean(*Calculator)

■ Caution This pointcut type is supported only in XML-based Spring AOP configurations, not in AspectJ annotations.

Combining Pointcut Expressions
In AspectJ, pointcut expressions can be combined with the operators && (and), || (or), and ! (not).
For example, the following pointcut matches the join points within classes that implement either the
ArithmeticCalculator or UnitCalculator interface:
within(ArithmeticCalculator+) || within(UnitCalculator+)

The operands of these operators can be any pointcut expressions or references to other pointcuts.

package com.apress.springenterpriserecipes.calculator;

import org.aspectj.lang.annotation.Aspect;
import org.aspectj.lang.annotation.Pointcut;

@Aspect
public class CalculatorPointcuts {

@Pointcut("within(ArithmeticCalculator+)")
public void arithmeticOperation() {}
