Spring form tag error

I think It is easy for a lot of peoples but I don't know what I'm doing wrong.

My controller:

@RequestMapping(value = "/novo", method = RequestMethod.GET)
public ModelAndView novoTimeSheet() {

    Usuario usuario1 = new Usuario(1L,"Leandro1","[email protected]");
    Usuario usuario2 = new Usuario(2L,"Leandro2","[email protected]");
    Usuario usuario3 = new Usuario(3L,"Leandro3","[email protected]");
    List<Usuario> usuarioList = new ArrayList<Usuario>();
    usuarioList.add(usuario1);
    usuarioList.add(usuario2);
    usuarioList.add(usuario3);

    Map<String, Object> model = new HashMap<String, Object>();
    model.put("usuarios", usuarioList);

    return new ModelAndView("timesheetcrud/novo", "timesheetcruddto", model);
}

It's working:

    <td>Usuário :</td>
    <td>
        <select id="usuarios" name="usuarios">
            <c:forEach items="${timesheetcruddto.usuarios}" var="usuario">
                <option value="${usuario.id}"><c:out value="${usuario.nome}"/></option>
            </c:forEach>
        </select>
    </td>

But I'd like to use spring tag and I put this:

    <td>Usuário :</td>
    <td>
        <td>
            <form:select id="id_usuario" path="usuarios">
                <form:option value="0" label="--- Select ---" />
                <form:options items="${usuarioList}"/>
            </form:select>
        </td>
    </td>

It isn't work:

        <td>
            <form:select id="id_usuario" path="usuarios">
                <form:option value="0" label="--- Select ---" />
                <form:options items="${usuarios}"/>
            </form:select>
        </td>

And It's wrong:

org.springframework.beans.NotReadablePropertyException: Invalid property 'usuarios' of bean class [java.util.HashMap]: Bean property 'usuarios' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

I'd like to know what's benefit to use spring tags instead of JSTL.

Thanks

You can improve your code like 

`<form:select path="usuarioList">
   <form:option value="NONE" label="--- Select ---"/>
   <form:options items="${usuarios}" />
</form:select>
`

Also please change your variable name for more suitable one like 

     List<Usuario> usuarios= new ArrayList<Usuario>();
    usuarios.add(usuario1);
    usuarios.add(usuario2);
    usuarios.add(usuario3);

    Map<String, Object> model = new HashMap<String, Object>();
    model.put("UserList", usuarios);

It looks much good than earlier

You can do like this

<form:select path="usuarioList"> <form:options items="${usuarios}" /> </form:select>

usuarios is a list .. for a form, you need to bind an object

object will have a list with getters and setters.

  object.setUsuarioList(usariolist);
  model.put("object", object);

and then 

  <form:options items="${object.usuarioList}"/>
