Skip to content

how can we read a file using rest Api, which is locally present in my system?

I have to make a controller class and there I have to define get method to read a txt file which i have in my local storage.I made a controller and I don’t know if it is really a correct one

Answer

It looks like your text file has new lines. So can you try using streams?

@RestController
@RequestMapping("/api")
public class Controller {

    @GetMapping("/file")
    String getData(){
       String strLine="";
        try (BufferedReader br = new BufferedReader(new FileReader(new File("/path"))))
        {
            strLine= br.lines().collect(Collectors.joining("n"));  //this way next line text can also be returned into existing string & strLine will looks like exactly as your text file content
        } catch (IOException e) {
            e.printStackTrace();
        }
      return strLine;
    }

}
