CAS 5.3, where is LOGGER defined with @Slf4j?

[Yan Zhou]

Hello,

Looking at CAS 5.3 source code,   I need to customize action class, so I create a class with the same name/package in my overlay, but I cannot resolve compile error on LOGGER.

I understand with Lombok and @Slf4j, I get object: log  for free. But, I do not know how LOGGER is defined in CAS code.

Thx!

Yan

in action classes, I see this:

@Slf4j

public class SendPasswordResetInstructionsAction extends AbstractAction {

    

LOGGER.debug(...)   <== this is how logging is done, is this referring to the same logger object in parent?

In AbstractAction, i see this.

protected final Log logger = LogFactory.getLog(getClass());

Thanks,

Yan

Hi Yan,

To make @Slf4j works, see "https://apereo.github.io/cas/developer/Build-Process-5X.html#plugins" the Lombok plugin is what you want to look at.

Alternatively, going back in time to CAS 5.2.x and you will see how LOGGER is originally implemented. Your cited class "SendPasswordResetInstructionAction" is not a very good example, since it is inconsistent  with other similar classes (in CAS 5.2.x that is~).

When you look at most other classes that implement LOGGER, like this:
https://github.com/apereo/cas/blob/5.2.x/support/cas-server-support-oidc/src/main/java/org/apereo/cas/oidc/web/controllers/OidcAuthorizeEndpointController.java
https://github.com/apereo/cas/blob/5.3.x/support/cas-server-support-oidc/src/main/java/org/apereo/cas/oidc/web/controllers/OidcAuthorizeEndpointController.java

And only looking at the part about LOGGER and @Slf4j. You will see how the LOGGER evolve into @Slf4j :) 

Hope that make sense to you!

Cheers!

You need this file in your overlay project.
