2、調用測試

1         RmtShellExecutor exe = new RmtShellExecutor("10.190.1.123", "root", "root");2         try {3             int i = exe.exec("sh /dcdata/etl/runjobinfo/cscscs.sh");4             System.out.println(i);5         } catch (Exception e) {6             e.printStackTrace();7             logger.info("執行dsjob錯誤" + e.getMessage());8         }
