In order to implement Logging using Spring AOP I followed these simple steps. But it seems like its not working. Any help would be useful
1) Created MyLoggingAspect class
import org.aspectj.lang.ProceedingJoinPoint;
public class MyLoggingAspect
{
public MyLoggingAspect() {
super();
System.out.println("Instantiated MyLoggingAspect");
}
public Object log(ProceedingJoinPoint call) throws Throwable
{
System.out.println("from logging aspect: entering method [" + call.toShortString()
+"] with param:"+call.getArgs()[0] );
Object point = call.proceed();
System.out.println("from logging aspect: exiting method [" + call.toShortString()
+ "with return as:" +point);
return point;
}
}
2) Created a class (TixServiceImpl) where I want logging
public class TixServiceImpl implements TixService{
@Override
public void calculateSomething() {
String s = "did some calculation..";
System.out.println(s);
}
@Override
public String getTixName() {
return null;
}
}
3) Created a spring-aspectj.xml file
<beans...
<bean id="LoggingAspect" class = "MyLoggingAspect"/>
<aop:config>
<aop:aspect ref="LoggingAspect">
<aop:pointcut id="myCutLogging"
expression="execution(* TixService*.*(..))"/>
<aop:around pointcut-ref="myCutLogging" method="log"/>
</aop:aspect>
</aop:config>
</beans>
4) Created a simple test client (TixClient)
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;
public class TixClient {
public static void main(String[] a){
ApplicationContext context = new FileSystemXmlApplicationContext("conf/spring-aspectj.xml");
TixService tix = new TixServiceImpl();
tix.calculateSomething();
String s = tix.getTixName();
System.out.println("End of the the client invocation!!");
}
}
5) It gives me the following Output
..
Instantiated MyLoggingAspect
did some calculation..
End of the the client invocation!!
