Override JdbcRealmIdentity to pass custom principal name

[jeevanraj61]

Hi,

I am working on application to migrate from picketbox to Elytron security. We have a custom principal name with "username:sessionId". I need to override principal.getName() that we pass to JdbcRealmIdentity to pass just the username instead of entire prinipal name.

Please suggest me best possible way to do it.

You can use a principal-transformer to modify the principal. More specifically, you can use a pre-realm-principal-transformer to transform the principal before using it to load the identity from the realm. This blog post makes use of a custom pre-realm-principal-transformer: Implementing a custom Elytron principal transformer and this blog post explains the purpose and use of different principal-transformers: Darran's WildFly Blog: WildFly Elytron - Principal Transformers, Realm Mappings, and Principal Decoders
