Why this Spring MVC controller method can't handle this POST Request (Content type 'application/x-www-form-urlencoded' not supported) - spring

Question

I am working on a Spring MVC application and I have the following problem.
Into a FreeMarker view (but is not so important that the view is made using FreeMarker) I have this form:
<form id="reg-form" name="reg-form" action="<#spring.url '/iscrizioneStep2' />" method="post">
<fieldset>
<div class="form-group">
<label for="cf">Codice fiscale:</label>
<input type="text" id="cf" name="codiceFiscale" class="form-control input-mm" placeholder="Inserisci il tuo codice fiscale" data-validation="[NOTEMPTY, NOSPACE, L==16, CF]" data-validation-label="codice fiscale" aria-required="true" tabindex="10">
</div>
<div class="form-group">
<div class="g-recaptcha" data-sitekey="6LcOfhcTAAAAAE3D2hsa3UcyTQ0PI4upcZ759FDa" tabindex="20"></div>
</div>
<button type="submit" class="btn btn-block submit-btn" aria-label="prosegui la registrazione" tabindex="30">Passaggio 2</button>
</fieldset>
</form>
As you can see the form is submittet to this action: action="<#spring.url '/iscrizioneStep2' />" performing a POST request.
This generate a POST request toward this URL (I see it using FireBug):
http://localhost:8080/iam-ssum-public/iscrizioneStep2?codiceFiscale=AAAAAAAAAAAAAAAA&g-recaptcha-response=
So I think that it should send the input field having name="codiceFiscale" into the POST request.
Then I have this controller method:
#RequestMapping(value = "/iscrizioneStep2", method = RequestMethod.POST)
public String iscrizioneStep2(#RequestBody(required = true) IscrizioneStep1Form iscrizioneStep1Form, Model model)
throws APIException {
/*
* Verifica se l'utenza è attivata per il codice fiscale
*/
String codiceFiscale = iscrizioneStep1Form.getCodiceFiscale();
..............................................................
..............................................................
..............................................................
return "myView";
}
So the data sended in the post request should be putted inside the IscrizioneStep1Form iscrizioneStep1Form parameter, that is:
public class IscrizioneStep1Form {
/**
* Codice fiscale
*/
private String codiceFiscale;
public String getCodiceFiscale() {
return codiceFiscale;
}
public void setCodiceFiscale(String codiceFiscale) {
this.codiceFiscale = codiceFiscale;
}
}
But the problem is that this HTTP POST request is not handled by the iscrizioneStep2() method. When I submit the form don't enter into this method and into the Eclipse console I obtain the following error message:
11:55:43,949 WARN [org.springframework.web.servlet.mvc.support.DefaultHandlerExceptionResolver] (http-localhost/127.0.0.1:8080-6) Handler execution resulted in exception: Content type 'application/x-www-form-urlencoded' not supported
Why? What am I missing? How can I fix this issue?

Answer 1

Try to add heders param to your RequestMapping annotation:
#RequestMapping(value = "/iscrizioneStep2", method = RequestMethod.POST,
headers = "content-type=application/x-www-form-urlencoded")

Answer 2

Try to remove #RequestBody(required = true) from your request method.
Here Spring Mvc Rest Webservice jstl form submittion HTTP Status 415 Content type 'application/x-www-form-urlencoded' not supported has the same problem.

Answer 3

There is no built-in converter that knows how to convert content of the type 'application/x-www-form-urlencoded to IscrizioneStep1Form. Simply omit #RequestBody. Form data is automatically mapped to objects.

Answer 4

The problem is that when we use application/x-www-form-urlencoded, Spring doesn't understand it as a RequestBody. So, if we want to use this
we must remove the #RequestBody annotation.
Then try the following:
#RequestMapping(value = "/iscrizioneStep2", method = RequestMethod.POST, consumes = MediaType.APPLICATION_FORM_URLENCODED_VALUE)
public String iscrizioneStep2(IscrizioneStep1Form iscrizioneStep1Form, Model model) throws APIException {
//method body where
}
Note that removed the annotation #RequestBody
