У меня проблема с Hibernate Validator. Я вставил в свой код аннотацию @Size, но когда я запускаю приложение на сервере Tomcat, я могу отправить без заполненного текстового поля. Что не так с этим кодом?
Класс клиента:
import javax.validation.constraints.NotNull;
import javax.validation.constraints.Size;
public class Customer {
private String firstName;
@NotNull(message="is required")
@Size(min=1, message="is required")
private String lastName;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
}
Класс CustomerController:
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import javax.validation.Valid;
@Controller
@RequestMapping("/customer")
public class CustomerController {
@RequestMapping("/showForm")
public String showForm(Model theModel) {
theModel.addAttribute("customer", new Customer());
return "customer-form";
}
@RequestMapping("/processForm")
public String processForm(
@Valid @ModelAttribute("customer") Customer theCustomer, BindingResult theBindingResult) {
if (theBindingResult.hasErrors()) {
return "customer-form";
} else {
return "customer-confirmation";
}
}
}
