I am trying to implement AOP based logging in Google - Guice. I have used "
*MethodInterceptor*" for this but it doesn't work. I have used same in
Spring by defining point-cuts. Everything is working fine there.
*Spring Code for AOP based logging -*
@Aspect
public class LoggingAspect {
private static Logger logger = LoggerFactory.getLogger(LoggingAspect.class
);
@Around("requiredLog()")
public Object bentoBoxAround(ProceedingJoinPoint proceedingJoinPoint) {
Object returnValue = null;
try {
logger.info("Entered into the method -> " + proceedingJoinPoint.
getSignature().toShortString()
+ " and input arguments are -> " + Arrays.asList(
proceedingJoinPoint.getArgs()));
returnValue = proceedingJoinPoint.proceed();
logger.info("Method Execution over !! " + proceedingJoinPoint.
getSignature().toShortString());
} catch (Throwable e) {
logger.error("Method has an exception " + e.getMessage());
}
return returnValue;
}
@Pointcut("within(org.cal.bento..*)")
public void allRequiredPakageLog() {
}
}
>From above code we can log all the class and method executions inside the "
org.cal.bento.*" package.
*Guice code for AOP based logging -*
public class GuiceLoggingInterceptor implements MethodInterceptor {
private static Logger logger = LoggerFactory
.getLogger(GuiceLoggingInterceptor.class);
@Override
public Object invoke(MethodInvocation invocation) throws Throwable {
Object returnValue = null;
try {
logger.info("GUICE - Entered into the method -> " + invocation.
getMethod().getName()
+ " and input arguments are -> " + Arrays.asList(
invocation.getArguments()));
returnValue = invocation.proceed();
logger.info("Method Execution over !! " + invocation.getMethod().
getName());
} catch (Throwable e) {
logger.error("GUICE - Method has an exception " + e.getMessage());
}
return returnValue;
}
}
*Binding Class -*
public class GuiceAopModule extends AbstractModule {
@Override
protected void configure() {
bindInterceptor(Matchers.any(), Matchers.any(), new
GuiceLoggingInterceptor());
}
}
Can we do similar in Guice for logging (write only one Aspect based class
for whole logging system). I don't want to modify every class.

Any help would be highly appreciated.
