java - Hibernate 3.6 customize the setter of one to many mapping -

i have simple @onetomany mapping:

public class member(){     ....     @onetomany(fetch = fetchtype.lazy, mappedby="member", orphanremoval=true)     private list<user> users;      @transient     private user firstuser;     ...      public setusers(list<user> users){       //if(users.size() > 0) this.firstuser = users.get(0);       this.users = users;     }  }  public class user(){     .....     @manytoone     @joincolumn(name = "user_id")     private member member; } 

here i'd set this.firstuser = users.get(0) if mapped users length greater 0. doesn't work if put code directly setter method commented line in member, example, read member object users size 5, tried print firstuser, firstuser still null, expected result should users.get(0).

any idea?

you try following:

public class member(){     ....     @onetomany(fetch = fetchtype.eager, mappedby="member", orphanremoval=true)     private list<user> users;      @transient     private user firstuser;     ...      public setuser(list<user> users){       if(users.size() > 0) this.firstuser = users.get(0);       this.users = users;     }      @postload     public void settransientuser() {         this.setusers(this.users);     }  }
