To apply this audit advice, you need a pointcut . In AOP, a pointcut determines where
to apply this advice. You can combine an advice and pointcut into an advisor. Listing 6-24
shows the advisor for this example.
Listing 6-24. audit-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=" http://www.springframework.org/schema/beans"
xmlns:xsi=" http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation=" http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-2.5.xsd ">
<!--advisor -->
<bean id="auditAdvisor"
class="org.springframework.aop.aspectj.AspectJExpressionPointcutAdvisor">
<property name="advice" ref="auditAdvice" />
<property name="expression" value="execution(* *.underwrite*(..))" />
</bean>
<!—other beans -->
</beans>
As shown in Listing 6-24, the audit advice is applicable to any method starting with
the word underwrite . Finally, you need to create proxies for the beans matching the
expression property of the advisor. Listing 6-25 shows the automatic proxy creator bean.
Listing 6-25. audit-config.xml
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns=" http://www.springframework.org/schema/beans"

<!--advisor -->
<bean id="auditAdvisor"
class="org.springframework.aop.aspectj.AspectJExpressionPointcutAdvisor">
<property name="advice" ref="auditAdvice" />
<property name="expression" value="execution(* *.underwrite*(..))" />
</bean>
