import javax.persistence.Column;
import javax.persistence.Id;
import javax.persistence.Entity;
import javax.persistence.Table;

@Entity
@Table(name = "PERSON")
public class Person implements Serializable {

    public Person(Long id, String name, String email) {
        this.id = id;
        this.name = name;
        this.email = email;
    }

    }

    public String getEmail() {
        return email;
    }

    public void setEmail(String email) {
        this.email = email;
    }
}

package com.dao.impl;

import com.dao.IPersonRepository;
import com.model.Person;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.beans.factory.annotation.Autowired;

@Repository
public class PersonRepository implements IPersonRepository {
    public PersonRepository() {
    }

    private Session getSession() {
        try {
            return sessionFactory.getCurrentSession();
        }catch (Exception e) {
            return sessionFactory.openSession();
        }
    }
    @Autowired(required = true)
    private SessionFactory sessionFactory;

    @Override
    @Transactional
    public void insertPerson(Person person) {
        Session s = getSession();
        s.save(person);
    }

Are you creating Person while setting the id? If so, it might be the problem, as hibernate thinks the object already exists and tries to update instead of insert. Try using a sequence and let hibernate set the id.
