I'm trying to manually add an individual email error message to my model but nothing is displaying in the view.
I think it may be how I'm creating or attached the ObjectError to the BindingResult.
I'm adding the error inside the catch.
Here is the contents of result.errors when I leave email field empty and JSR-303 annotations kick in (error displays in view):
[Field error in object 'user' on field 'email': rejected value []; codes [NotEmpty.user.email,NotEmpty.email,NotEmpty.java.lang.String,NotEmpty]; arguments [org.springframework.context.support.DefaultMessageSourceResolvable: codes [user.email,email]; arguments []; default message [email]]; default message [may not be empty]]
Here is the contents of of result.errors after I manually add the ErrorObject(email error does not display in view):
[Error in object 'email': codes []; arguments []; default message [An account already exists for this email.]]
Controller:
@RequestMapping(value = "/registration", method = RequestMethod.POST)
public ModelAndView post(@Valid User user, BindingResult result)
{
if (result.hasErrors())
{
ModelAndView modelAndView = new ModelAndView(
Consts.MODEL_RESISTER_PAGE);
modelAndView.addObject("user", user);
return modelAndView;
}
else
{
try
{
userService.addUser(user);
ModelAndView modelAndView = new ModelAndView(
Consts.MODEL_CARD_REPORTS_HOME_PAGE);
modelAndView.addObject("userRegisteredSuccess", Boolean.TRUE);
return modelAndView;
}
catch (DataIntegrityViolationException ex)
{
ObjectError error = new ObjectError("email","An account already exists for this email.");
result.addError(error);
ModelAndView modelAndView = new ModelAndView(
Consts.MODEL_RESISTER_PAGE);
modelAndView.addAllObjects(result.getModel());
modelAndView.addObject("user", user);
return modelAndView;
}
}
}
My Model:
@Entity
public class User implements Serializable
{
/**

private static final long serialVersionUID = -5232533507244034448L;
@Id
@GeneratedValue(strategy = GenerationType.AUTO)

@NotEmpty
@Size(min=2, max=15)
private String firstname;
@NotEmpty

private String surname;
@NotEmpty
@Email
private String email;
@NotEmpty
@Size(min=6, max=10)
private String password;
public Long getId()
{
return id;
}
public void setId(Long id)
{
this.id = id;
}
public String getFirstname()
{
return firstname;
}
public void setFirstname(String firstname)
{
this.firstname = firstname;
}
public String getSurname()
{
return surname;
}
public void setSurname(String surname)
{
this.surname = surname;
}
public String getEmail()
{
return email;
}
public void setEmail(String email)
{
this.email = email;
}
public String getPassword()
{
return password;
}
public void setPassword(String password)
{
this.password = password;
}
}

I usually call result.rejectValue("property", "error.object");
to add errors to BindingResult
. If you want to add a global object error, you could use result.reject("error.object");
.
So, in your code, instead of:
ObjectError error = new ObjectError("email","An account already exists for this email.");
result.addError(error);
try with:
result.rejectValue("email", "error.user", "An account already exists for this email.");
Check the reference here.
Hope this helps.
