获取配置文件的值配置文件在项目目录下，如果打成jar包会在jar包所在的同级目录下

  Properties p = new Properties();

  try {
   InputStream in = new BufferedInputStream(new FileInputStream("BankDebitBack.properties"));
   p.load(in);
   in.close();

String user = p.getProperty("USER","");--获取配置文件的值

　　} catch (FileNotFoundException e) {

log.error(e.getMessage());
    } catch (IOException e) {

log.error(e.getMessage());
     } catch (Exception e) {
   log.error(e.getMessage());
  }
