Java receiving text file inputs in REST

Let's say I have a GET endpoint which receives a String ("this is a string") and returns a modified version of it ("This is a string!"):

@GetMapping(value = "/test")
@ResponseBody
public String getText(@RequestParam String text) {
    return modified(text);
}

How would I adjust this code for it to receive the same piece of text in a .txt file?

Solution 
  • @GetMapping(value = "/try")
@ResponseBody
public String getText(@RequestParam("filePath") String filePath) throws 
IOException {
File file = new File(filePath);
BufferedReader reader = new BufferedReader(new FileReader(file));
String line = reader.readLine();
StringBuilder builder = new StringBuilder();
while (line != null) {
    builder.append(line);
    line = reader.readLine();
}
reader.close();
return modified(builder.toString());

    }
