Class SpringSecurityUserRegistration

java.lang.Object

de.javakaffee.web.msm.serializer.kryo.SpringSecurityUserRegistration

All Implemented Interfaces:

KryoCustomization

public class SpringSecurityUserRegistration
extends Object
implements KryoCustomization

Provides a custom kryo serializer for the Spring Security User class.

This is needed because the User class internally contains a collection of GrantedAuthority, which is actually a TreeSet with a Comparator. During deserialization kryo creates a TreeSet *without* any comparator and therefore expects that the contained items are Comparable, which is not the case for SimpleGrantedAuthority - ClassCastException.

Motivated by issue #145: Deserialization fails on ConcurrentHashMap in Spring User object .
