private final String PATH = "/mbp/file/cmbc/rechg/"+new SimpleDateFormat("yyyyMMdd").format(new Date())+"/单笔联机代付THWJ_XXX_"+new SimpleDateFormat("yyyyMMdd").format(new Date())+".txt";
private static final Logger log = Logger.getLogger(ReExchangeUpload.class);

@Override
public void execute(JobExecutionContext arg0) throws JobExecutionException {

    List<String> list = new ArrayList<String>();
    try {
        File file = new File(PATH);
        log.info("文件目录"+PATH);
        if (file.isFile() && file.exists()) {
            InputStreamReader isr = new InputStreamReader(new FileInputStream(file), "GBK");
            BufferedReader br = new BufferedReader(isr);
            String lineTxt = null;
            while ((lineTxt = br.readLine()) != null) {
                if ("########".equals(lineTxt)) {
                    break;
                }
                list.add(lineTxt);
            }
            br.close();
        } else {
            log.info("文件不存在");
            return;
        }
    } catch (Exception e) {
        log.info("文件读取失败");
