[jboss-user] [JBoss AOP] - Help with simple Interceptor please
hi guys,
i'm trying to setup an interceptor that that intercepts all method calls to classes in
a specified package and then does some logging... i just can't get it to work...
No errors are thrown when JBoss starts up but it's not calling my Interceptor at
runtime...
please assist, many thanks!
here's what i tried:
jboss version: jboss-4.0.5.GA
my class (i packaged this class into a jar & put the jar in my server/default/lib):
package za.co.rmb.redi.common.aop;
|
| import org.apache.commons.logging.Log;
| import org.apache.commons.logging.LogFactory;
| import org.jboss.aop.advice.Interceptor;
| import org.jboss.aop.joinpoint.Invocation;
| import org.jboss.aop.joinpoint.MethodInvocation;
|
| public class LogInterceptor implements Interceptor {
| private Log log = null;
|
| public String getName() {
| return "LogInterceptor";
| }
|
| public Object invoke(Invocation invocation) throws Throwable {
| Object result = null;
| if (invocation instanceof MethodInvocation) {
| MethodInvocation mi = (MethodInvocation) invocation;
| if (log == null) {
| log = LogFactory.getLog(mi.getTargetObject().getClass());
| }
| String methodName = mi.getMethod().getName();
| log.debug("START - " + methodName);
| result = invocation.invokeNext();
| log.debug("END - " + methodName);
| }
| return result;
| }
| }
my descriptor (it's name is redi-aop.xml and it's in server/default/deploy):
<?xml version="1.0" encoding="UTF-8"?>
| <!DOCTYPE aop PUBLIC
| "-//JBoss//DTD JBOSS AOP 1.0//EN"
| "http://www.jboss.org/aop/dtd/jboss-aop_1_0.dtd">
|
| <aop>
| <interceptor name="LogInterceptor"
| class="za.co.rmb.redi.common.aop.LogInterceptor"
| scope="PER_CLASS"/>
|
| <bind pointcut="execution(* za.co.rmb.*->*(..))">
| <interceptor-ref name="LogInterceptor"/>
| </bind>
| </aop>
