Configuring proxing beans in Spring aop + cglib

[omickron]

We've got a Spring 3.1 web-application using spring-aop with cglib library.
spring.xml:

    <context:annotation-config/>
    <aop:aspectj-autoproxy proxy-target-class="true"/>

That means that a proxy will be created using cglib for every bean.

Now we need to use a db connection pool bean with com.mchange.v2.c3p0.ComboPooledDataSource:

    <bean id="connectionPool" class="com.mchange.v2.c3p0.ComboPooledDataSource" destroy-method="close">
    <!-- here are some properties -->
    </bean>

The problem is the ComboPooledDataSource class is marked as final. And cglib can't proxy final classes.

How to mark "connectionPool" bean not to be proxied?

By fixing your pointcuts, it shouldn't be proxied in the first place so find the pointcut that triggers proxy creation for this bean.

I confugured pointcuts with @annotation rule.
I've got an annotation @Log and mark my beans with it.
My AbstractDao bean uses connectionPool this way:

@Autowired
private DataSource connectionPool;

And AbstractDao is marked with @Log annotation.

Pointcut looks this way:

@Pointcut("(@annotation(Log) || @target(Log)) && !@annotation(NotLog)")
public void allLog() {
}

It seems to me that connectionPool isn't triggered by allLog pointcut... Or I'm mistaken?
