This is my upload image code in Spring Boot:
String root = ctx.getRealPath("/");
File dir = new File(root + File.separatorChar + "images");
if (!dir.exists())
dir.mkdir();
String path = dir.getAbsolutePath() + File.separatorChar
+ product.getProductName() + "."
+ file.getContentType().split("/")[1];
System.out.println(path);
File file1 = new File(path);
try {
FileOutputStream fod = new FileOutputStream(file1);
fod.write(file.getBytes());
fod.close();
product.setProductPicture("/images/" + product.getProductName()
+ "." + file.getContentType().split("/")[1]);
} catch (IOException e) {
e.printStackTrace();
}
The uploading of files works fine, only problem with this code is that when i use ctx.getRealPath("/")
it returns temporary location and when i restart the spring boot app i loose already existing files which was already uploaded as it creates a new temporary directory.
This causes some problem as i also have to display this pics on my site and now it returns "image not found error".
So I needed a solution which will allow me to upload files in a permanent location and serve files from there on the browser.
Note: I'm using thymeleaf for views.
I found a solution for my problem. I created a new function which will only return bytes[]
and sent as response body as follows:
@RequestMapping(value = "image/{imageName}")
@ResponseBody
public byte[] getImage(@PathVariable(value = "imageName") String imageName) throws IOException {
File serverFile = new File("/home/user/uploads/" + imageName + ".jpg");
return Files.readAllBytes(serverFile.toPath());
}
And in html <img alt="Image" th:src="@{image/userprofile}" width="250" height="250"/>
