Error upload file with Spring Security and Thymeleaf - spring

Question

In my situation I have a controller class with Spring Data and validator of Spring MVC which handle form data with a template made with Thymeleaf 2.1.1
I use Spring Framework 3.2.8 and Spring Security 3.2.3.
Controller
#RequestMapping(value = "/save", method = {RequestMethod.POST, RequestMethod.GET })
public String save(#RequestParam("curriculumVitae") MultipartFile curriculumVitae, #Valid #ModelAttribute("user") User user, BindingResult result, Model model, Pageable pageable) {
try {
user.setCurriculumVitae(curriculumVitae.getBytes());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
userRepository.save(user);
return "/crudUser";
View
<form id="myform"
action="#"
th:action="#{${url}+'/save'+'?' + ${_csrf.parameterName} + '=' + ${_csrf.token}}"
th:object="${user}"
th:method="post"
enctype="multipart/form-data">
<div class="col-sm-2 col-lg-2">
<div th:class="form-group" th:classappend="${#fields.hasErrors('curriculumVitae')}? has-error">
<label class="control-label" scope="col"
th:text="#{crudUser.curriculumVitae}">Curriculum Vitae</label>
<input class="form-control input-sm" type="file" th:field="*{curriculumVitae}" name="curriculumVitae" />
</div>
</div>
</form>
The error displayed in my log is:
Failed to convert property value of type org.springframework.web.multipart.commons.CommonsMultipartFile to required type byte[] for property curriculumVitae; nested exception is java.lang.IllegalArgumentException: Cannot convert value of type [org.springframework.web.multipart.commons.CommonsMultipartFile] to required type [byte] for property curriculumVitae[0]: PropertyEditor [org.springframework.beans.propertyeditors.CustomNumberEditor] returned inappropriate value of type [org.springframework.web.multipart.commons.CommonsMultipartFile]
Thanks in advance for who will help me.

SOLVED!
In the stacktrace I have forget of set the maxUploadSize in the MultiPartResolver in my java configuration file with a value more high then default.
#Bean
public MultipartResolver multipartResolver() {
CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
multipartResolver.setMaxUploadSize(500000000);
return multipartResolver;
}
