The part of Rest I've circled almost all google and I still can not solve. the problem is exactly that when I make the query or I give a sava postman day or straight through the url to see if Json returns and nothing happens just the 404 error ..

follow my Code .. (My Class that I take care of my Rest)

package br.gov.sp.fatec.web.controller;

import java.util.Collection;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.http.HttpStatus;

import org.springframework.stereotype.Service;
import org.springframework.web.bind.annotation.PathVariable;

import br.gov.sp.fatec.model.Usuario;
import br.gov.sp.fatec.service.IServiceUsuario;
import br.gov.sp.fatec.service.UsuarioServiceImpl;
import br.gov.sp.fatec.view.View;



@RestController
@RequestMapping(value = "/usuario")
public class UsuarioWebController {




    @Autowired
    IServiceUsuario serviceusu;


    public void setUsuarioService(IServiceUsuario serviceusu) {
        this.serviceusu = serviceusu;
    }


    @RequestMapping(value="usuario/{nome}")
    public ResponseEntity<Collection<Usuario>>listarUsuarioNome(@PathVariable("nome") String nome){
        return new ResponseEntity<Collection<Usuario>>(serviceusu.buscar(nome),HttpStatus.OK);

    }


    @RequestMapping(value = "usuario/save", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
            @JsonView({View.All.class, View.Alternative.class})
        // E possivel indicar o status por anotacao, mas sera fixo, sem possibilidade de tratar erros
            @ResponseStatus(HttpStatus.CREATED)
            public Usuario save(@RequestBody Usuario usuario, HttpServletRequest request,HttpServletResponse response) {

            usuario = serviceusu.salvar(usuario);
            response.addHeader("Location", request.getServerName() + ":" + request.getServerPort() +
            request.getContextPath() + "/usuario/getById?id=" + usuario.getId());

Try the URL host:porta/contexto/usuario/usuario/save , because that's how you mapped the route according to your controller, if you want to remove this / repeated user just take "%" of the% desired method.

Example:

@RequestMapping(value = "save", method = RequestMethod.POST, produces = MediaType.APPLICATION_JSON_VALUE)
