display image from file system in jsp using spring boot - spring

Question

I have Java Web Application using Spring Boot, I want to display in JSP page ,images which are in an extern folder (E:/images) in file system.
I looked too many pages in google,I found on stackoverflow a post that say I should write a servlet to get the image : am I missing something or should I do it with an other way , please give me more details I m kind of new to Spring. thanks for your help.
in my Controller :
#RequestMapping(value="/images",method = RequestMethod.GET)
public #ResponseBody void affichimage(#RequestParam("id") Integer Iddd,HttpServletResponse response,HttpServletRequest request) throws IOException
{
Annonce annonce=new Annonce();
annonce=annoncedao.findOne(Iddd); // get the right annonce from
//database
File imageFile = new File(annonce.getimage()); // in image I have
//the link to images ex : E:/images/image1.jpeg
response.setContentType("image/jpeg");
BufferedImage image = ImageIO.read(imageFile);
ImageIO.write(image, "image/jpeg", response.getOutputStream());
}
in JSP :
< img class="imagesaffichage" src="/images?id=${annonce.id}" alt="No image"/>
I also added this to my application :
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**")
.addResourceLocations("file:///E:/images/");
}

Answer 1

I found the solution , I had to change the above method :
#RequestMapping(value="/images",method = RequestMethod.GET)
public #ResponseBody void affichimage(#RequestParam("id") Integer
Iddd,HttpServletResponse response,HttpServletRequest request) throws
IOException,NullPointerException
{
Annonce annonce=new Annonce();
annonce=annoncedao.findOne(Iddd); // get the right annonce from
//database
File imageFile = new File(img);
response.setContentType("image/jpeg");
InputStream in=new FileInputStream(imageFile);
IOUtils.copy(in, response.getOutputStream());
}
