Method interceptor in java classes not from beanfactory

[Kris Philippaerts]

Hi,

I'm trying to use spring AOP in my project on classes that are not declared as beans in the bean factory.

I tried the NameMatchMethodPointcutAdvisor, but I couldn't manage to get it working. I also tried out the AutoProxyCreator classes, but they only seem applicable for bean in the bean factory.

So, is it possible to add a method interceptor in classes that are not defined in the bean factory? Any leads?

Thanks a lot!

You could also use Spring AOP programmatically.

Ah, so it's possible to add a method interceptor at runtime?? Do you have an example of this? I couldn't find munh info about this in the manual.

Kris,

I think this is what you are looking for: http://www.springframework.org/docs/....html#aop-prog.

I do it a bit differently, first, I write a config xml like this (this code shows introduction advice):

  <bean name="beanAdvisor" class="spring.ExtensionAdvisor" singleton="false">
    <constructor-arg index="0">
			<bean class="Application.BeanExtensionImpl" singleton="false" />
		</constructor-arg>
    <constructor-arg index="1">
			<value>Application.BeanExtension</value>
		</constructor-arg>
  </bean>
  <bean name="bean" class="org.springframework.aop.framework.ProxyFactoryBean">
    <property name="singleton"><value>false</value></property>
    <property name="proxyInterfaces">
      <value>Application.BeanView</value>
    </property>
    <property name="interceptorNames">
      <list>
        <value>beanAdvisor</value>
      </list>
    </property>
  </bean>

And then use code like this to "wire" up the instance:

   BeanView target = null;
   if( context.containsBean("bean") ) {
      target = (BeanView) context.getBean("bean");
      ((Advised) target).setTargetSource(beanInstance);
   }

This allows me the flexibility of defining all the advice in a config file.

Cheers
