Hello
we've tried the metrics example from the
http://docs.jboss.org/aop/aspect-framework/userguide/en/pdf/jbossaop_userguide.pdf
within our own bank project.
After the first deploy it works very well. But after the second time it doesnt
work anymore. Any help would be appreciated.
jboss-aop.xml:
| ?xml version=1.0 encoding=UTF-8?
| aop
| bind pointcut=execution(public boolean
de.bootlab.bank.BankSessionBean-ueberweisen(..))
| interceptor class=test.Metrics/
| /bind
| /aop
|
metrics.java:
| package test;
|
| import java.lang.reflect.Method;
| import org.jboss.aop.advice.Interceptor;
| import org.jboss.aop.joinpoint.Invocation;
| import org.jboss.aop.joinpoint.MethodInvocation;
| /*

|
|
| public class Metrics implements Interceptor {
|
| public String getName() { return Metrics; }
|
| public Object invoke(Invocation invo) throws Throwable {
| long start = System.currentTimeMillis();
| try{
| Object value = invo.invokeNext();
| System.out.println(Return value: +value);
| return value;
| }catch(Exception ex){
| throw ex;
| }finally{
| long end = System.currentTimeMillis() - start;
| Method m = ((MethodInvocation)invo).getMethod();
| System.out.println(Method + m.toString() + Time
needed: + end + ms);
| }
| }
|
| }
