springboot jar包 无法读取静态资源文件

参考 springboot项目读取resources目录下的文件的9种方式

	Resource resource = resourceLoader.getResource("classpath:static/jkbw/jkbw4.txt");try{InputStream inputStream = resource.getInputStream();BufferedReader reader = new BufferedReader(new InputStreamReader(inputStream));StringBuilder out = new StringBuilder();String newLine = System.getProperty("line.separator");String line;while ((line = reader.readLine()) != null) {out.append(line);out.append(newLine);}return out;} catch (IOException e) {e.printStackTrace();}
