In Spring Framework, I am facing a strange issue while working with AOP. I have the following simple bean class for a greeting:
public class HelloBean {
private String message;
public String getMessage() {
return message;
}
public void setMessage(String message) {
this.message = message;
}
public void displayGreeting() {
System.out.println("Hello");
}
}
Below spring config:
<beans>
<bean id="hello" class="com.att.spring.main.HelloBean"/>
<bean id="serviceCheck" class="com.att.spring.main.ServiceCheck" />
<aop:config>
<aop:aspect ref="serviceCheck">
<aop:pointcut id="greet"
expression="execution(* *.getMessage(..))" />
<aop:before pointcut-ref="greet"
method="preRunMessage" />
<aop:after pointcut-ref="greet"
method="postRunMessage" />
</aop:aspect>
</aop:config>
</beans>
AOP Advice Methods:
public class ServiceCheck {
public void preRunMessage() {
System.out.println("Runs before the greeting");
}
public void postRunMessage() {
System.out.println("Runs after the greeting");
}
}
Test Class:
public class Test {
public static void main(String[] args) {
ApplicationContext context = new ClassPathXmlApplicationContext(
"spring-beans.xml");
HelloBean hello = (HelloBean) context.getBean("hello");
hello.setMessage("Hello World");
System.out.println(hello.getMessage());
}
}
Output:
Runs before the greeting
Runs after the greeting
Hello World
Question:
Why are both advices (before and after) getting printed when I use getter as a pointcut. The advice work correctly when i use pointcut on displayGreeting() method??
