Thanks Rod.

Yeah, AspectWerkz proxy could be a viable option if it delivers 
significantly better performance than standard JDK proxy

Re: [Springframework-developer] Extending Spring AOP

[Rod J. <ro...@in...>]

1. Performance (marketing more than reality, but marketing can't be ignored)
2. Problems with the CGLIB implementation. Another approach may well deliver better results.
3. Potential to add additional features, if the approach works out well.

It should be largely transparent to the developer view. I introduced the AopProxyFactory interface 
for that reason.

I agree, I'll put together a quick prototype either today or next week

Re: [Springframework-developer] Extending Spring AOP

[Rod J. <ro...@in...>]

Rob

I would favour the Java code-based approach, using Velocity. I think that should deliver extremely 
good performance, and would rather we don't commit to maintaining a byte code approach.

I don't believe there is any problem using code generation with our API. Indeed, I always meant to 
implement it, but performance optimization of the AOP framework has never been of any significance 
in practice. Only for marketing, as has been apparent recently :-)

A Java based approach should definitely allow significant optimization, and would hopefully be 
simpler than the CGLIB approach and more maintainable. So there would be a real advantage, besides 
performance. There should be a particular optimization for methods with only before or after advice, 
skipping the present use of an interceptor to wrap them. The

I would recommend hand-authoring a Java class, and benchmarking, to see exactly what the gains are, 
before putting a lot of effort into the approach. (But I'm sure they'll be large.) But I think this 
is definitely good stuff!

[Springframework-developer] Extending Spring AOP

[Rob H. <ro...@ca...>]

All,

I am planning to add to an additional proxy implementation to Spring to 
solve some of the problems we are experiencing with other approaches and 
to allow for additional optimizations and advice types to be added in 
the most efficient way.

Currently, I'm looking at two separate approaches - Java-based using 
Janino and Bytecode-based using SERP. The Java-based approach should be 
quite simple to create and could be coupled with Velocity to externalize 
much of the boilerplate code needed for the creation of proxy classes. 
Alternatively we could add a simple abstraction layer on top of Janino, 
a la .NET CodeDOM (good idea James). The bytecode approach is much more 
complex and will be harder to debug but it would probably allow for 
absolute raw performance.

I am comfortable with either approach although I think that Janino would 
be ideal for our purposes.

Your thoughts?

Rob

The trick was in using the DataSourceUtils.getConnection(..) which I

Re: [Springframework-developer] Transaction Management

[Colin S. <col...@ex...>]

Brian,

Just use HibernateTransactionManager, and make sure you use the same 
DataSource both for the Hibernate LocalSessionFactoryBean, and for your 
Spring-based JDBC code. Your JDBC code _will_ share the same transaction 
as used for Hibernate.

The HibernateTransactionManager ensures that the connection used for 
Hibernate is also bound to the current thread and synchronized to the 
transaction (keyed to the datasource), and when the JDBC code tries to 
use this datasource it will reuse the bound connection.

Regards,
Colin

[Springframework-developer] Transaction Management

[Brian M. <br...@ap...>]

If I am using both hibernate and a raw datasource in an application, is 
there a mechanism for having them both work in the same transaction 
other than JTA?

The LocalSessionFactoryBean is configured to use the same data source 
as I am attempting to use standalone -- but I am not sure if a 
transaction manager exists which will do DS transactions around 
hibernate transactions, etc?

Here is sample test case (with manually demarcated tx's for testing)

transactionManager is the HibernateTransactionManager and the 
DataSource is just a DriverManagerDataSource

I have can happily throw a DataSourceTransactionManager into the mix, 
but figure best to ask about ways to do this =)

     public void testHibTxManagerSharesDSTxWithHib() throws Exception
     {
         final DefaultTransactionDefinition def = new 
DefaultTransactionDefinition();
         
def.setPropagationBehavior(TransactionDefinition.PROPAGATION_REQUIRED);
         final PlatformTransactionManager ptm = 
(PlatformTransactionManager) 
getContext().getBean("transactionManager");
         final TransactionStatus status = ptm.getTransaction(def);

         final IDBI dbi = (IDBI) getContext().getBean("dbi");
         final Handle one = dbi.open();

         final SessionFactory factory = (SessionFactory) 
getContext().getBean("sessionFactory");
         final Session sesion = factory.openSession();

         one.execute("insert into batch_log (batch_id) values (87)");
         assertFalse(one.getConnection().getAutoCommit());

         final BatchLog log = (BatchLog) sesion.get(BatchLog.class, new 
Long(87));
         assertNotNull(log);

         ptm.commit(status);
     }

Thanks!

For some (to be determined) reason one of the AOP tests fails on AMD64 =
(cont. build) and not on the other machines. Juergen and I looked at it =
shortly in between on the of sessions at JavaPolis.

Darren, could you have a look at this. The test should clearly succeeed, =
there's two method invocations being done with a nopinterceptor added to =
the proxy, but it somewho doesn't get into the interceptor (should be 2, =
but is 1).

Does'nt this method belong to a common superclass?
It would be nice to have it on a ResourceBundleViewResolver, f.i.

You mention that it's easier to test with Spring but you haven't made =
the point why.  Could be interesting to make a link between dependency =
injection, programming to interfaces and the ease of testing.  I think =
it's an area where Spring adds great value.

Calvin,

thanks for spotting this. It is fixed in CVS.

The other thing we should look at fixing is the Exception handling. At the
moment most things are just defined to throw Exception. We can probably tidy
that up some.

[Springframework-developer] javadoc update for TransactionSynchronizationManager

[Calvin S. <ca...@th...>]

*The javadoc for 
org.springframework.transaction.support.TransactionSynchronizationManager.getResourceMap() 
looks like it's slightly out of synch with the code, since it says that 
it returns null in the case of no bound resources, but it actually 
returns an empty map, as you can see below.

Here is the relevant snippet from **TransactionSynchronizationManager:*
*
    /**
     * Return all resources that are bound to the current thread.
     * <p>Mainly for debugging purposes. Resource managers should always 
invoke
     * hasResource for a specific resource key that they are interested in.
     * @return Map with resource keys and resource objects,
     * or null if currently none bound
     * @see #hasResource
     */
    public static Map getResourceMap() {
        Map map = (Map) resources.get();
        if (map == null) {
            map = new HashMap();
        }
        return Collections.unmodifiableMap(map);
    }

Re: [Springframework-developer] How do I get access to the target object of a cglib-proxied-object?

[Dmitriy K. <dko...@ru...>]

Hunter,

you could always cast any SpringAOP proxy to the "Advised" instance from 
which you could get the "target" object via "TargetSource" In order to 
be able to do that the "opaque" property of "ProxyConfig" must be set to 
"false" (which is "false" by default). So consider you have "MyService" 
AOP proxy backed by MyServiceImpl target:

...
TargetSource targetSource = ((Advised)myService).getTargetSource();

MyServiceImpl target = (MyServiceImpl)targetSource.getTarget();

Regards,
Dmitriy.

[Springframework-developer] How do I get access to the target object of a cglib-proxied-object?

[Hunter K. <re...@ei...>]

Hi there, I'm mucking about with some advanced reflection stuff in Spring.
I need to examine the Fields of an object, unfortunately sometimes the object 
I have is an AOP proxy, for certain methods.  I know that AopUtils.isAopProxy 
will tell me this, which is fine, but I haven't been able to figure out a way 
of getting the actual target object - I noticed that there is a certain 
amount of stuff for detecting if the object is returning itself, and 
returning the proxy, etc.

Is there some way of getting at the target object, given the proxy?

Thanks,

Hunter

Re: [Springframework-developer] Portlet support (again)

Yes. Sorry, I forgot to delete SimplePortletFormController and mention 
the name change. When I introduced the other classes I got pretty 
confused by all these PortletSomething names, so I decided to keep the 
names as used in the org.springframework.web.servlet tree. This way the 
correspondence between classes is obvious and the names are simpler.

I know :-(. But I still haven't heard any good reason why not to allow 
RenderRequest attributes, so maybe they'll make up their minds.
