Issue
In hybris, is there an easy way to know which implementing class is being used for a certain Spring bean?
I mean, I can override a Bean by doing something like this:
<alias name="myCheckoutFacade" alias="checkoutFacade"/>
<bean id="myCheckoutFacade" class="com.pedra.facades.checkout.impl.MyCheckoutFacadeImpl" scope="tenant" parent="defaultCheckoutFacade">
<property name="commerceCheckoutService" ref="myCommerceCheckoutService"/>
</bean>
... so now when Spring needs to create a bean with the alias checkoutFacade the implementing class will be MyCheckoutFacadeImpl as opposed to the overridden defaultCheckoutFacade which was defined in some other xml configuration file.
So is there a way to know at runtime which implementing class is being used for a certain Spring bean definition? Without having to debug the code, I mean.
Solution
Beanshell or Groovy :-)
Checking the implementing class of a bean is just one of the many cool things you can do at runtime with Beanshell or Groovy.
Disclaimer: Be careful running Beanshell or Groovy code on a production machine!
Log in to the HAC and go to Console > Beanshell or Groovy
Execute the following code in either Beanshell or Groovy to get your implementing class:
de.hybris.platform.core.Registry.getApplicationContext().getBean("checkoutFacade");
Both consoles will show the result of the last expression in the Result tab.
In the Groovy console for Hybris 5.x, simple execute the following:
checkoutFacade
As you can see, each bean is automatically def-ed into each Groovy script.
As for Beanshell, you could create a bean function in Beanshell:
import de.hybris.platform.core.Registry;
import de.hybris.platform.commercefacades.order.CheckoutFacade;
Object bean(String beanName)
{
return Registry.getApplicationContext().getBean(beanName);
}
CheckoutFacade checkoutFacade = (CheckoutFacade) bean("checkoutFacade");
print(checkoutFacade);
I ended up using Beanshell so much that I created my own wrapper application that allows me to develop Beanshell in Eclipse, and use Eclipse as the Beanshell console. But that's a whole other post!
