SpringBoot 读取 resources下的文件报错 cannot be resolved to absolute file path because it does not reside in the file system: jar

报错

原来代码，在调试不会报错，正式会报错

/**
     * 从文件中加载私钥
     *
     * @param path 私钥文件名
     * @return 是否成功
     * @throws Exception
     */
    public static String loadKeyByFile(String path) throws Exception {
        try {
            BufferedReader br = new BufferedReader(new FileReader(path));
            String readLine = null;
            StringBuilder sb = new StringBuilder();
            while ((readLine = br.readLine()) != null) {
                if (readLine.charAt(0) == '-') {
                    continue;
                } else {
                    sb.append(readLine);
                    sb.append('
');
                }
            }
            br.close();
            String ret=sb.toString();
            return ret;
        } catch (IOException e) {
            throw new Exception("私钥数据读取错误");
        } catch (NullPointerException e) {
            throw new Exception("私钥输入流为空");
        }
    }

--下面调用
Resource publicResource = new ClassPathResource("cert/rsa_public_key.pem");
        File publicFile=publicResource.getFile();
RSAHelper.loadKeyByFile(publicFile.getPath());

改后代码

 /**
     * 通过文件流取文件路径
     * @param source
     * @return
     * @throws Exception
     */
    public static String loadKeyByResource(String source) throws Exception {
        try {
            Resource resource = new ClassPathResource(source);
            InputStream in = resource.getInputStream();
            InputStreamReader isReader= new InputStreamReader(in);
            BufferedReader br = new BufferedReader(isReader);
            String readLine = null;
            StringBuilder sb = new StringBuilder();
            while ((readLine = br.readLine()) != null) {
                if (readLine.charAt(0) == '-') {
                    continue;
                } else {
                    sb.append(readLine);
                    sb.append('
');
                }
            }
            br.close();
            String ret=sb.toString();
            return ret;
//            BufferedReader br = new BufferedReader(isReader);
//            int length = in.available();
//            byte[] buffer = new byte[length];
//            int len= IOUtils.read(in, buffer, 0, length);
//            String ret=new String(buffer);
//            return ret;
        } catch (IOException e) {
            throw new Exception("公、私钥数据读取错误");
        } catch (NullPointerException e) {
            throw new Exception("公、私钥输入流为空");
        }
    }
