最近在尝试用Java调用Powershell，搜了狠多资料，终于发现下面的可行方案
推荐第一种，因为对于第二种，假如命令为：& "C:\Program Files\Markin\selenium\CloseNousedApp.ps1" 就不会执行，也不报错

1 executePSScript("C:/Program Files/automationscripts/Sample/Markin/src/actions/selenium/CloseNousedApp.ps1","");
2 executePSCommand("Write-Host \"Markin\"");

 public static String executePSCommand(String command) throws Exception 
    {
          //String cmd = "cmd /c c:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell -noprofile -noexit -executionPolicy restricted Set-ExecutionPolicy -Scope Process RemoteSigned " + command;
      	String cmd = "cmd /c c:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell -ExecutionPolicy RemoteSigned -noprofile -noninteractive " + command;
          return exec(cmd);
    }
  
  	public static String executePSScript(String scriptFilename, String args) throws Exception {
		if (!new File(scriptFilename).exists())
			throw new Exception("Script file doesn't exist: " + scriptFilename);
		
		String cmd = "cmd /c c:\\Windows\\System32\\WindowsPowerShell\\v1.0\\powershell -ExecutionPolicy RemoteSigned -noprofile -noninteractive -file \"" + scriptFilename + "\"";
		if (args != null && args.length() > 0)
			cmd += " " + args;
		return exec(cmd);
	}
  
  
    private static String exec(String command) throws Exception 
    {        
    	StringBuffer sbInput = new StringBuffer();
        StringBuffer sbError = new StringBuffer();
        
		Runtime runtime = Runtime.getRuntime();
		Process proc = runtime.exec(command);
		proc.getOutputStream().close();
    
       	InputStream inputstream = proc.getInputStream();        
       	InputStreamReader inputstreamreader = new InputStreamReader(inputstream);
        BufferedReader bufferedreader = new BufferedReader(inputstreamreader);
        
        String line;
        while ((line = bufferedreader.readLine()) != null) 
        {
        	sbInput.append(line + "\n");
        }
        
        inputstream = proc.getErrorStream();
        inputstreamreader = new InputStreamReader(inputstream);
        bufferedreader = new BufferedReader(inputstreamreader);
        while ((line = bufferedreader.readLine()) != null) 
        {
           		sbError.append(line + "\n");
        }
        if (sbError.length() > 0)
        	throw new Exception("The command [" + command + "] failed to execute!\n\nResult returned:\n" + sbError.toString());

       		return "The command [" + command + "] executed successfully!\n\nResult returned:\n" + sbInput.toString();
	}
