Hi I am reading image from MongoDB and trying to pass that to JSP page but it is not passing properly from my controller. i am thinking i am almost edge to the solution but not getting exactly where i am doing mistake. Please let me know if you find any mistake.
here insertMedia method reading image from file and storing into DB and then returning back that image.
i am passing userMediaSave as image value to JSP, you can get that at tag like
img src=${userMediaSave} alt="Profile images"
My Controller:
@RequestMapping(value = "/userMediaSave", method = RequestMethod.GET)
public ModelAndView mediaLoadSuccess(HttpServletRequest request,HttpServletResponse response,
@ModelAttribute("mediaBean") MediaBean mediaBean) throws IOException, ServletException {
ModelAndView model = null;
File filePart = mediaBean.getMediaImage();
if (filePart != null) {
InputStream inputStream = new FileInputStream(filePart);
GridFSDBFile imageForOutput = null;
try {
imageForOutput = loginDelegate.insertMedia(inputStream, request.getContentType(), filePart.getName());
mediaBean.setExistedMedia(imageForOutput);
OutputStream out= null;
if(imageForOutput!=null){
InputStream is = imageForOutput.getInputStream();
ByteArrayOutputStream buffer = new ByteArrayOutputStream();
int nRead;
byte[] data = new byte[16384];
while ((nRead = is.read(data, 0, data.length)) != -1) {
buffer.write(data, 0, nRead);
}
byte[]imagenEnBytes = buffer.toByteArray();
buffer.flush();
response.setContentType("image/jpg" );
response.setContentLength(imagenEnBytes.length);
model = new ModelAndView("userMedia");
request.setAttribute("userMediaSave", imagenEnBytes);
return model;
} else {
System.out.println("inside uploadMedia page -ve");
}
} catch (SQLException e) {
e.printStackTrace();
} finally{
//out.close();
}
}
return model;
}
JSP is:
<body onload="checkMessage()">
<form:form id="mediaForm" method="get" action="userMediaSave" modelAttribute="mediaBean">
<table border="1" cellpadding="1" cellspacing="1"
style="width: 500px;" align="center">
<tbody>
<tr>
<td colspan="4" align="center">Name : Welcome to Media App</td>
</tr>
<tr>
<td rowspan="3">Profile Image</td>
<td>Upload Images</td>
<td><input type="file" name="mediaImage" /></td>
</tr>
<tr>
<td> </td>
<td><input name="upload" type="submit" value="Upload" /></td>
</tr>
</tbody>
</table>
<table border="1" cellpadding="1" cellspacing="1"
style="width: 500px;" align="center">
<tbody>
<tr>
<td>User has some existed Media Album</td>
</tr>
<tr>
<td>
<img src=${userMediaSave} alt="Profile images" style="width:100px;height:100px;">
</td>
</tr>
</tbody>
</table>
</form:form>
am i passing image from controller to JSP properly? if not please let me know which way i have to pass it.
