how to convert oracle.sql.BLOB to an image in spring mvc

Question

I am trying to display an image coming from my database in sql developer that has the field BLOB

public class Alojamento {
    @RequestMapping(value = "/alojamento")
    public ModelAndView test(HttpServletResponse response,
                             HttpServletRequest request) throws IOException {
        List<SpringWebMVC.s2.DAL.FotoAlojamento> FOTOInstance =
                SpringWebMVC.s2.BLL.Fotos.readAllFotoAlojamento();
        ModelAndView mview = new ModelAndView("alojamento");
        mview.addObject("fotoalojamentos", FOTOInstance);
        return mview;
    }
}

Code in my Controller, this was for me to see what type of value blob field brings

<div class="responsive" th:each="fotoalojamento: ${fotoalojamentos}">
    <div class="gallery">
        <a target="_blank" href="img_5terre.jpg">
        </a>
        <div class="desc" th:text="${fotoalojamento.getFotoalo()}"></div>
    </div>
</div>

Result:

So, how i can with this value oracle.sql.BLOB@516a6064 convert into an image to display ?
