JSR-299 Extension for enabling Interceptors Dynamically

General
----------

InterDyn is a JSR-299 (CDI - Context and Dependency Injection for Java)
Extension which allows adding Interceptors to CDI beans without having
to put any extra annotation into the code.

InvoMon is a simple CDI Interceptor which counts invocations of CDI beans
and outputs the top results at the end of each request.



Building
----------

$> mvn clean install


InterDyn Usage
----------

Just place this jar into your classpath and add a
configuration for it by creating a file

META-INF/struct/interdyn.properties

which contains something like the following content

# start of interdyn.properties
enabled=true
rule.1.match=.*ServiceImpl
rule.1.interceptor=net.struberg.devtools.cdi.invomon.InvocationMonitored
rule.2.match=net.struberg.devtools.cdi.interdyn.test.domainobjects.*
rule.2.interceptor=TestInterceptorAnnotation
#  end of interdyn.properties

The match section contains the reg exp of the classes which should get intercepted
and the interceptor section contains the name of the interceptor BindingType
annotation.


Invocation Monitor example
--------------------------

This is a fully functional (but still rudimentary) logging Interceptor which
can be used by InterDyn. It will count all your observed class and 
method invocations and also take the duration period.

The top values will be logged (Level.INFO) at the end of each servlet request.


Configuration
-------------

The maximum numbers of log lines might be configured with a system property:

-DMAX_LOG_LINES=15


Example
-------

A sample output looks like the following:
