jax-rs检索表单参数

Question

我正在尝试使用HttpServletRequest从发布的表单中检索传递给jax-
rs的一些参数。但是，我的请求对象始终为我的参数返回空值。我不是要这样做吗？我已经在下面发布了代码，并发送了示例请求。

这是我的服务：

@Path("/")
@Stateless
public class HomeController {

    @Context
    private HttpServletRequest request;
    @Context
    private HttpServletResponse response;
    @EJB
    private LoginServiceLocal loginService;

    @POST
    @Path("/authenticate")
    @Consumes("application/x-www-form-urlencoded")
    public void authenticate() throws Exception {
        String email = request.getParameter("email");
        String password = request.getParameter("password");
        if (loginService.authenticate(email, password)) {
            response.sendRedirect("/app");
        } else {
            request.setAttribute("authenticationError", "Invalid email/password.");

        }
    }
}

请求示例：

@POST
@Path("/authenticate")
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
public void authenticate(@FormParam("email") String email, @FormParam("password") String password) throws Exception {

    if (loginService.authenticate(email, password)) {
        response.sendRedirect("/app");
    } else {
        request.setAttribute("authenticationError", "Invalid email/password.");

    }
}
