I have an image in database. I want to retreive the image and display it in web page using angular js. After fetching data i have byte array. How do i send the data to the html page. I am having issues with the below code.. Kindly help.
When i click the link to view the image, page is sending 2 get requests to the server instead of one. It is sending request continuously for 2 times.
Note : I have tried using the below link.. But it didn't work
AngularJS - Show byte array content as image
Below is my js file
app.controller('aboutCtrl', function($scope,$http,$location) {
$scope.message = 'This is Add new order screen';
var url = '/Angular/login';
$http.get(url).success(function(result) {
$scope.image = result.image;
})
});
//html
<img data-ng-src="data:image/PNG;base64,{{image}}">
Java class file
public String getImage() throws FileNotFoundException{
String byteStr=null;
try
{
Connection con= DbConnect.getConnection();
String sql ="select * from image_data where id=1";
PreparedStatement ps=con.prepareStatement(sql);
ResultSet rs = ps.executeQuery();
while(rs.next())
{
Blob b=rs.getBlob(2);
byte barr[]=b.getBytes(1,(int)b.length());
byteStr = new String(barr);
}
}catch(Exception e){
e.printStackTrace();
}
return byteStr;
}
Servlet Code
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// TODO Auto-generated method stub
System.out.println("inside get");
JSONObject result= new JSONObject();
Retreive rt = new Retreive();
result.put("image", rt.getImage());
response.setContentType("application/json");
PrintWriter out = response.getWriter();
out.write(result.toString());
out.flush();
out.close();
}
