spring boot 读取yml文件 springboot读取文件内容

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();
