I am a newbie to Hibernate and Spring and I am getting the above exception while executing the application.
I am trying to fetch the values of a record from the database.
Following is the exception that I am getting :-
message Request processing failed; nested exception is org.hibernate.HibernateException: /hibernate.cfg.xml not found
description The server encountered an internal error that prevented it from fulfilling this request.
exception

Following are my file :-
POJO
public class Usertable {
int id;
String userName;
String password;
public int getId() {
return id;
}
public void setId(int id) {
this.id = id;
}
public String getUserName() {
return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Controller
//@Controller
public class HomeController extends AbstractController{
//private static final Logger logger = LoggerFactory.getLogger(HomeController.class);

Kindly help me with this issue.Thanks in advance.!
The thing is you shouldn't instantiate your hibernate configuration in your handle of a request but rather let spring instantiate your session factory and inject it into your controller and retrieve the session from there. Doing this, then you won't have to implement a session factory for each request made to your application.
You can check this question or the official documentation to have details on how to instantiate your session factory via spring.
This will (indirectly) solve your problem.
