To complete the registration using Spring AOP, I followed these simple steps. But it does not seem to work. Any help would be helpful
1) Created a class MyLoggingAspect
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 to keep a log
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 the 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) He gives me the next Exit
... Instantiated MyLoggingAspect did some calculation.. End of the the client invocation!!
