i'm unsure on join strategy should use. kind of highly appreciated, since solving priority me.

thanks in advance!

it template

class house {      @manytoone(fetch = fetchtype.lazy)     @joincolumn(name = "fk_town")     private town town;      @onetomany(mappedby = "house")     private list<owner> owners;  }  class owner {      @manytoone(fetch = fetchtype.lazy)     @joincolumn(name = "fk_house")     private house house;      @onetoone     @joincolumn(name = "fk_owner_info")     private ownerinfo ownerinfo;  }  class ownerinfo {      @onetoone(mappedby = "ownerinfo", fetch = fetchtype.lazy)     private owner owner;  }

the simplest case fetch owners owner info

from house h inner join fetch h.owners h.town.id = :townid
