Witam, zaczynam naukę SpringMVC i podczas walidacji danych wyskakuje taki błąd:

Widzę, że błąd jest w metodzie

addContact(Contact c)

ale nie wiem jak go naprawić.

Klasy zawarte w projekcie:
Model

@Entity
@Table(name = "contacts")
public class Contact implements Serializable {
	@Id
	@GeneratedValue
	private Integer id;

	private String firstname;

	@NotNull
	@Size(min = 5)
	private String lastname;

	//gettery i settery
}

@Repository
public class ContactDAOImpl implements ContactDAO {

	@Autowired
	public SessionFactory sessionFactory;

	@Override
	public void addContact(Contact contact) {
		sessionFactory.getCurrentSession().save(contact);
	}
	
	//pozostałe metody
}

@Service
public class ContactServiceImpl implements ContactService {

	@Autowired
	private ContactDAO contactDAO;

	@Transactional
	public void addContact(Contact contact) {
		contactDAO.addContact(contact);
	}
}

Kontroler

@Controller
public class ContactController {

	Logger log = LoggerFactory.getLogger(ContactController.class.getName());

	@Autowired
	private ContactService contactService;

	@RequestMapping("/")
	public String listContacts(Map<String, Object> map) {

		map.put("contact", new Contact());
		map.put("contactList", contactService.listContact());

		return "contact";
	}

	@RequestMapping(value = "/add", method = RequestMethod.POST)
	public String addContact(@Valid Contact contact, BindingResult result) {

		contactService.addContact(contact);
		return "redirect:/";
	}
}

Formularz w widoku

<form:form method="post" action="add" commandName="contact"
			modelAttribute="contact">
			<table>
				<tr>
					<td><form:label path="firstname">
							<spring:message code="label.firstname" />
						</form:label></td>
					<td><form:input path="firstname" /></td>
				</tr>
				<tr>
					<td><form:label path="lastname">
							<spring:message code="label.lastname" />
						</form:label></td>
					<td><form:input path="lastname" /></td>
					<td><form:errors path="lastname" cssClass="error" /></td>
				</tr>
				<tr>
					<td colspan="2"><input type="submit"
						value="<spring:message code="label.addcontact"/>" /></td>
				</tr>
			</table>
		</form:form>

Do konfiguracji Spring'a dodałem:

<bean class="pl.pawel.spring.service.ContactServiceImpl" id="contactService"/><bean class="pl.pawel.spring.dao.ContactDAOImpl" id="contactDAO"/>

Co robię źle?

Podałeś za krótkie nazwisko:

    @NotNull
    @Size(min = 5)
    private String lastname;

Podany przykład jest ze strony
http://viralpatel.net/blogs/spring3-mvc-hibernate-maven-tutorial-eclipse-example/
i chcę do formularza dodawania kontaktów dodać walidację danych.
Ma ktoś jakieś sugestie jak to zrobić, bo mnie już brak pomysłów na rozwiązanie tego problemu.

ostatnio ktoś na forum miał chyba podobny problem, bo strona zapisała mu się w html, a nie xhtml

Rozwiązanie mojego problemu jest następujące:

  • dodanie do konfiguracji spring'a
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
	<property name="webBindingInitializer">
		<bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer">
			<property name="validator" ref="validator" />
		</bean>
	</property>
</bean>

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean" />
  • oraz modyfikacja metody kontrolera addContact
@RequestMapping(value = "/add", method = RequestMethod.POST)
	public String addContact(@ModelAttribute("contact") @Valid Contact contact,
			BindingResult result, ModelMap map) {

		if (result.hasErrors()) {
			map.put("contactList", contactService.listContact());
			return "contact";
		}
		contactService.addContact(contact);
		map.put("contactList", contactService.listContact());
		return "Done";
	}
