Question

Java

Good time of the day!
there is a site written in java, you need to add the error pages mentioned in the title above to the client part and to the admin part!
the design in the client part and the admin panel are actually different and different error pages are needed!
the site is written in Spring, no xml, instead of xml annotation!)
plz tell me how to implement it, otherwise there are examples using xml in Google!)
