HTTP Status 500 - Request processing failed; nested exception is org.hibernate.HibernateException: /hibernate.cfg.xml not found - spring

Question

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;

this.id = id;

return userName;
}
public void setUserName(String userName) {
this.userName = userName;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}

Kindly help me with this issue.Thanks in advance.!

Answer 1

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.

Answer 2

benzonico and KHY thanks for your inputs. The first mistake that I was doing was I placed the hibernate.cfg.xml inside src/main/java/com/me/app/ which should have been src/main/java/. This worked for me. The next part about TypedMismatch was
user = (Usertable)hibsession.get(Usertable.class, userName);
I was trying to get the String reference from the database which was actually Integer. So that solved the typedMismatchException.
I will definitely try injecting the session factory into my code through spring. Since I am new to this frameworks I learnt a loads while discussing with you and trying the new codes.
Thanks again for your valuable feedback.
