                        cmdCommand.append(StringPool.SPACE).append(entry.getValue());
                    }

                BufferedReader bufferedReader = new BufferedReader(
                        new InputStreamReader(process.getInputStream(), "GBK"));
                String line = null;
                while((line=bufferedReader.readLine()) != null) {
        
                    stringBuilder.append(line+"\n");
                }
                return stringBuilder.toString();
            } catch (Exception e) {
        
                return e.getMessage();
            }
        }
    }

**使用案例：**

public ApiResult install(InstallDTO dto) {
        
         Map<String,Object> params = new HashMap<>();
         // 可以传递bat参数
         params.put("%1",dto.getDefaultName());
         params.put("%2",dto.getOvaDir());
         String result = excute(CmdRunEnum.INSTALL.getDesc(), params, true);
         return ApiResult.successMap("cmd",result);
     }
     
    protected String excute(String file, Map<String,Object> params, boolean isCloseWindow){
        
         return CMDUtil.excuteBatFile(file,params,isCloseWindow);
    }

**bat的参数接收：**

::变量
    SET DEFAULT_DIR=%VBOX_MSI_INSTALL_PATH%
    SET DEFAULT_NAME=%1
    SET OVA=%2
