c# - Nhibernate envers, use dependency injection to add user into revision entity -

after reading this , this come near solution not end since miss how apply implementation.

i have custon revision entity , revision listner:

public class _nhreventity : defaultrevisionentity {     public virtual int idutente { get; set; } }  public class enversrevisionlistener : irevisionlistener {     private int _username = 0;      public enversrevisionlistener(iusermanagement um) : base() {         _username = um.utentecorrente.id;     }      public void newrevision(object revisionentity) {         var casted = revisionentity _nhreventity;         if (casted != null) {             casted.idutente = _username;         }     } } 

and sessionfactory

public class sessionfactory : idisposable {     private static isessionfactory _sessionfactory;     private static nhibernate.cfg.configuration cfg = new nhibernate.cfg.configuration();     static readonly object factorylock = new object();      private static void initializesessionfactory() {         _sessionfactory = fluently.configure()                 .database(mssqlconfiguration.mssql2008                 .connectionstring(c => c.fromappsetting("fluentnhibernateconnection"))                 .showsql())                 .mappings(m => m.fluentmappings.addfromassembly(assembly.getexecutingassembly())                         )                    .exposeconfiguration(setupenvers)                                           .exposeconfiguration(config => new schemaupdate(config).execute(false, true))                 .buildsessionfactory();     }      private static void setupenvers(nhibernate.cfg.configuration cfg) {         var enversconf = new nhibernate.envers.configuration.fluent.fluentconfiguration();         enversconf.audit<autitedclass>();                irevisionlistener revlistner = new enversrevisionlistener();         enversconf.setrevisionentity<_nhreventity>(e => e.id, e => e.revisiondate, revlistner);         cfg.integratewithenvers(enversconf);     }      internal isession opensession() {         lock (factorylock) {             if (_sessionfactory == null) {                 initializesessionfactory();             }         }         nhibernate.isession session = _sessionfactory.opensession();         return session;     }        } 

core problem how make work injection in revisionlistner:

public enversrevisionlistener(iusermanagement um) 

edit:

going on working see real quest: private static void initializesessionfactory: since it's static there no way inject reference in it. must find different way

solved porting dependency injection unitofwork class:

public class unitofwork : iunitofwork { private static readonly object _syncroot = new object();

    private itransaction _transaction;     private sessionfactory _nhhelper;     internal isession _session;     public unitofwork(sessionfactory sf)     {         //contract.ensures(_session.isopen);         _nhhelper = sf;         inizializzasessione();     }     public void inizializzasessione()     {         lock (_syncroot)         {             if (_session == null || _session.isopen == false)             {                 _session = _nhhelper.opensession();             }         }     } 

and session factory:

public class sessionfactory : idisposable {      private static isessionfactory _sessionfactory;     private static nhibernate.cfg.configuration cfg = new nhibernate.cfg.configuration();             static readonly object factorylock = new object();     iusermanagement um;       public sessionfactory(iusermanagement ium)     {         um = ium;     }      private static void initializesessionfactory(iusermanagement um, bool generetedb = false)     {         _sessionfactory = fluently.configure()                 .database(mssqlconfiguration.mssql2008                 .connectionstring(c => c.fromappsetting("fluentnhibernateconnection"))                 .showsql())                 .mappings(m => m.fluentmappings.addfromassembly(assembly.getexecutingassembly())                                                 .conventions.addfromassemblyof<sessionfactory>()                         )                    .exposeconfiguration(config => setupenvers(config, um))                                         .exposeconfiguration(config => new schemaupdate(config).execute(false, true))                 .buildsessionfactory();     }      private static void setupenvers(nhibernate.cfg.configuration cfg, iusermanagement um)     {         try         {             var enversconf = new nhibernate.envers.configuration.fluent.fluentconfiguration();              irevisionlistener revlistner = new enversrevisionlistener(um);             enversconf.setrevisionentity<revisionentity>(e => e.id, e => e.revisiondate, revlistner);          }         catch (exception ex)         {             throw ex;         }      }      internal isession opensession()     {         lock (factorylock)         {             if (_sessionfactory == null)             {                 initializesessionfactory(um);             }         }         nhibernate.isession session = _sessionfactory.opensession();          return session;     } }
