integracontroller.java

@requestmapping("/users") public  modelandview users() {     list<myuser> p =dq3.usersa2();     (myuser p1 : p){         system.out.println(p1.getusername());     }     modelandview m=new modelandview();     m.setviewname("users");     m.addobject("list",p);     return m; } 

dao.java

@transactional @repository public class dao {     private session session;     @autowired     private myuser u;     @autowired     private post p;     @autowired     private person per;     @autowired     private roles r;     @autowired     private answer a;     @autowired     private hibernatetemplate ht;      public  list<myuser> usersa2()     {         list<myuser> p2;            p2 = ht.executefind(new hibernatecallback<object>() {             @override             public object doinhibernate(session sn) throws hibernateexception, sqlexception {                 list<myuser> p1 =sn.createquery("select e.username myuser e").list();                 return p1;             }            });         return p2;     } 

your query looks this: "select e.username myuser e"

the e.username part return list of username strings. should from myuser myuser objects.

something like:

list<myuser> p1 =sn.createquery("from myuser").list();
