How to take user image in session and add to html?

Question

I’m developing a web application using spring boot. I already have saved image of the user in the database, now I would like to assign the image of the user logged in the session in the profile photo of my Dashboard. How to do this? I can bring other information like name and cnpf, but his image can not.

My controller:

@Controller
public class IndexController {

@Autowired
private UsuarioService service;
@RequestMapping("/index")
public ModelAndView index(HttpSession session) {
    Usuario usuario = service.findByEmail(SecurityContextHolder.getContext().getAuthentication().getName());
    ModelAndView mv = new ModelAndView("/home");
    session.setAttribute("usuario", usuario);
    return mv;
}

My html page:

<div class="avatar">

                    <img th:src="@{/session.usuario/image/{image_id}(image_id=${session.usuario.id})}">
                </div>
                <div class="title">
                    <h1 class="h6" th:text="${session.usuario.nome}"></h1>
                    <p class="h2" th:text="${session.usuario.cnpjCpf}"></p>
                </div>
            </div>

Hello, in this question there is an answer that may be useful, the second solution has the line:

Mav.addObject("userImage", base64Encoded );

Switch to:

Session.setAttribute("photoUsuario", base64Encoded);

And in JSP use:

<img src="data:image/jpeg;base64,${fotoUsuario}" />
