第一种方式：利用cmd方式

* 执行cmd命令 
          * 
          * @param command 
          * @throws IOException 
          */ 
         public static String executeCmd(String command) throws IOException { 
              System.out.println("Execute command : " + command); 
              Runtime runtime = Runtime.getRuntime(); 
              Process process = runtime.exec("cmd /c " + command); 
              BufferedReader br = new BufferedReader(new InputStreamReader(process.getInputStream(), "UTF-8")); 
              String line = null; 
              StringBuilder build = new StringBuilder(); 
              while ((line = br.readLine()) != null) { 
                  System.out.println(line); 
               build.append(line); 
              } 
              return build.toString(); 
         }
    
         public static void main(String[] args) throws IOException {
             String ECGFile="D:\\12ECG\\ECGAnalyser\\5.ECG";
             String path="D:\\12ECG\\ECGAnalyser\\";
             String type="1";
             String command="D:\\12ECG\\ECGAnalyser\\ECGAnalyser\t"+ECGFile+"\t"+path+"\t"+type;
             System.out.println(command);
             executeCmd(command); 
    ｝

第二种方式使用ProcessBuilder调用cmd方式：

/** 
     * 启动应用程序 
     * 
     * @param programName 
     * @return 
     * @throws IOException 
     */ 
    public static void startProgram(String programPath) throws IOException { 
     log.info("启动应用程序：" + programPath); 
     if (StringUtils.isNotBlank(programPath)) { 
      try { 
       String programName = programPath.substring(programPath.lastIndexOf("/") + 1, programPath.lastIndexOf(".")); 
       List<String> list = new ArrayList<String>(); 
       list.add("cmd.exe"); 
       list.add("/c"); 
       list.add("start"); 
       list.add("\"" + programName + "\""); 
       list.add("\"" + programPath + "\""); 
       ProcessBuilder pBuilder = new ProcessBuilder(list); 
       pBuilder.start(); 
      } catch (Exception e) { 
       e.printStackTrace(); 
       log.error("应用程序：" + programPath + "不存在！"); 
      } 
     } 
    }

第三种方式：使用Desktop启动应用程序

/** 
     * 启动应用程序 
     * 
     * @param programName 
     * @return 
     * @throws IOException 
     */ 
    public static void startProgram(String programPath) throws IOException { 
     log.info("启动应用程序：" + programPath); 
     if (StringUtils.isNotBlank(programPath)) { 
      try { 
       Desktop.getDesktop().open(new File(programPath)); 
      } catch (Exception e) { 
       e.printStackTrace(); 
       log.error("应用程序：" + programPath + "不存在！"); 
      } 
     } 
    }
