spring boot读取本地文件

File file = ResourceUtils.getFile("classpath:face/1112.txt");

            InputStream inputStream = new FileInputStream(file);

            InputStreamReader treader =

                    new InputStreamReader(inputStream);

            BufferedReader tBff = new  BufferedReader(treader);

            String FileReaderstr = tBff.readLine();

            tBff.close();

ResourceUril读取了文件地址，字符流读取到文件数据

上面这种在idea上可以但是放到服务器上会失效

下面这种才是干货：

ClassPathResource classPathResource = new ClassPathResource("face/1112.txt");

            InputStream inputStream = classPathResource.getInputStream();

            InputStreamReader treader =

                    new InputStreamReader(inputStream);

            BufferedReader tBff = new BufferedReader(treader);

            String FileReaderstr = tBff.readLine();

            tBff.close();
