Hello I have a screen that uploads a file and saves in a folder in a directory of the computer until and saved in the database the complete path of the image, now I want to display this image in a table for example I made the example of the first faces but not conisgo display the image.

<p:column headerText="Foto">
     <p:lightBox styleClass="imagebox" id="lighbox1">  
          <h:outputLink value="#{item.imagem}" title="Nature 1">  
           <h:graphicImage name="#{salaBean.exibirImagem(item)}" id="nature1" style="height: 77px; width: 100px" />  
           </h:outputLink>
       </p:lightBox>
 </p:column>

in my bean I bring the complete example path: D: data Sar uploads Chrysanthemum.jpg

Answer 1

That way D:\dados\sar\uploads\ needs to be served by a Servlet, ie if I access http://localhost:8080/app/uploads, should have this directory mapped.

After browser request, read the disk path and return to response.getOutputStream(), without forgetting to set Content-Type to image\jpeg.

To read disk image use Imagery or Apache Commons-IO.

Answer 2

You can create a Streamedcontent to traffic your photo.

<p:graphicImage value="#{fotoMB.foto}" cache="disable"/>

public StreamedContent getFoto(){
    File foto=new File("suafoto.jpg");
    DefaultStreamedContent content=null;
    try{
        BufferedInputStream in=new BufferedInputStream(new FileInputStream(foto));
        byte[] bytes=new byte[in.available()];
        in.read(bytes);
        in.close();
        content=new DefaultStreamedContent(new ByteArrayInputStream(bytes),"image/jpeg");
    }catch(Exception e){
        log.error(e);
    }
    return content;
}
