Simplest way of customizing CAS Default Classes

[Prakash Thapa]

What could be the most simplest way of customizing the CAS library classes for CAS 7? I tried creating custom classes and registering it's bean. This method doesn't seem to be feasible for all the classes as few classes might not have been registered as Spring beans.


I am struggling a lot with the customization and would appreciate a lot if anyone has tried the simplest approach.

Till CAS 5, we just added classes with same name in same package and the customization was in place.

Prakash,

The overlay approach should still work.

What are some classes that you are trying to override, but they are not working?

It may be that the upstream classes have been modified or perhaps no longer exist.

The exact CAS version is '7.2.4'.

Hi Ray,

Some of the classes that I tried customizing are 'TerminateSessionAction', 'DefaultServiceTicketResourceEntityResponseFactory', 'DelegatedClientIdentityProviderConfigurationFactory', 'DelegatedClientIdentityProviderConfiguration' etc.

"It may be that the upstream classes have been modified or perhaps no longer exist."

>> Regarding this, I copied the exact default classes on same package before starting the customization. On keeping the breakpoints, the debugger stops at custom classes, but the actual code execution is from the default class itself (the logs added on custom classes are also not printed).

In CAS 7.x ...

If they are new classes, you can register them via including the class in:

src\main\resources\META-INF\spring\org.springframework.boot.autoconfigure.AutoConfiguration.imports

one class per line per class including package with out any ending delimiter: com.newco.service.MyService

If you are just overwriting an existing CAS class, just drop it into the same package.
