Contact class:

@Entity
@Table(name="CONTACTS")
public class Contact {

@Id
@Column(name="ID")
@GeneratedValue
private Integer id;

@Column(name="FIRSTNAME")
private String firstname;

@Column(name="LASTNAME")
private String lastname;

@Column(name="EMAIL")
private String email;

@Column(name="TELEPHONE")
private String telephone;


public String getEmail() {
    return email;
}
public String getTelephone() {
    return telephone;
}
public void setEmail(String email) {
    this.email = email;
}
public void setTelephone(String telephone) {
    this.telephone = telephone;
}
public String getFirstname() {
    return firstname;
}
public String getLastname() {
    return lastname;
}
public void setFirstname(String firstname) {
    this.firstname = firstname;
}

    this.lastname = lastname;
}
public Integer getId() {
    return id;
}
public void setId(Integer id) {
    this.id = id;
}

}

controller:

 @RequestMapping(value = "/edit/{contactId}", method = RequestMethod.GET)
public ModelAndView edit(@PathVariable("contactId") Integer contactId,
        HttpServletRequest request) {
    System.out.println("I was here");
    Contact contact = contactService.getContact(contactId);

    Map<String, Object> model = new HashedMap();
    model.put("contact", contact);

    return new ModelAndView("contact_edit", model);

The problem is not related to your getter, but the fact that by the time you are rendering the results, the Hibernate session has been closed (that’s what the org.hibernate.LazyInitializationException: could not initialize proxy - no Session implies.

To avoid this, you can either

Switch of lazy loading for your entity (i.e. Hibernate will populate the full entity when you load it inside your controller, when the session is active)
Or use the OpenSessionInView pattern, which will keep the Hibernate session open until the rendering of your JSP has completed.

EDIT:

Spring provides support for the OpenSessionInView pattern through the OpenSessionInViewFilter.
