package com.spring.demo;
import org.springframework.orm.hibernate5.HibernateTemplate;
public class EmployeeDao {
HibernateTemplate template;
public void setTemplate(HibernateTemplate template) {
this.template = template;
}

Answer 1

In this configuration you are missing transaction management configuration. Use #transactional annotation over your service method.
In you situation data is not committing in the database it just save the data and not commit the data in database.
