Every time I insert one input of the kind date in my form, the server returns error 400. I have tried everything, when I remove the field date makes no mistake.

My controller:

package br.com.starcode.agenda.controller;

import java.util.Date;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.format.annotation.DateTimeFormat;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.support.RedirectAttributes;

import br.com.starcode.agenda.domain.Usuario;
import br.com.starcode.agenda.service.UsuarioService;

@Controller
public class UsuarioController {

    @Autowired
    UsuarioService UsuarioService; 

    @RequestMapping(value="/usuario", params="new")
    ModelAndView novoUsuario() {
        Usuario usuario = new Usuario();
        usuario.setDataNascimento(new Date());
        return new ModelAndView("cadastrar-usuario")
                .addObject("usuario", usuario);
    }

    @RequestMapping(value="/usuario", method = RequestMethod.POST)
    ModelAndView confirmarNovo(
            Usuario novoUsuario,
            @RequestParam(value="dataNascimento", required=false) @DateTimeFormat(pattern="yyyy-MM-dd") Date dtNasc,
            RedirectAttributes redirectAttributes) {
        try {
            novoUsuario.setDataNascimento(dtNasc);
            //insert 
            UsuarioService.insert(novoUsuario);
            //success
            redirectAttributes.addFlashAttribute("msg", "Registro '" + novoUsuario.getIdUsuario() + "' inserido com sucesso!");
            return new ModelAndView("redirect:/");
        } catch (Exception e) {
            return new ModelAndView("cadastrar-usuario")
                    .addObject("erro", e.getMessage())
                    .addObject("usuario", novoUsuario);
        }
    }

}

And the JSP:

Source of the problem

This type of error is characteristic of Spring MVC and occurs when it fails to do the Binding any request data for some parameter or model.

In this case, it is because Spring MVC does not know what format is expected for the field dataNascimento of your class Usuario.

Even though I put the note @DateTimeFormat in your parameter dtNasc, Spring MVC will still try to fill the attribute of Usuario.

Simple solution, but not recommended

The simplest solution in your case would be to rename the field in your form so that Spring doesn’t try to do the Binding automatic in attribute dataNascimento.

However, I don’t recommend this because it would be unintuitive and Spring offers more than one way to solve the problem without skulking.

Set up a Property editor in the controller

Well, you must already know which fields input of the kind date send the values in the format yyyy-mm-dd, so you should report this to Spring somehow.

One of them is to configure a Property editor in its controlling class.

Example:

@InitBinder
void initBinder(WebDataBinder webDataBinder) {
    SimpleDateFormat dateFormat = new SimpleDateFormat("yyyy-MM-dd");
    dateFormat.setLenient(false);
    webDataBinder.registerCustomEditor(Date.class, new CustomDateEditor(dateFormat, true));
}

There is a functional example of this in example project I have on my Github.

Note that the above method affects the date interpretation for all requests from controller.

Configure the attribute in model

The problem would also be solved by annotating the attribute dataNascimento in your template class with the annotation @DateTimeFormat.

Example:

public class Usuario {

    ...

    @DateTimeFormat(pattern = "yyyy-MM-dd")
    private Date dataNascimento;

    ...

}
