在JSP页面中执行bash脚本 [英] executing a bash script from a jsp page

问题描述

我有previously写了执行Java类中的bash脚本，它运行在课前做其他检查。
运行时需要的参数; ./ SyncIPs.cmd 10.0.1.45 并执行一些命令。

I have previously written a bash script that executes a java class, it does other checks before running that class. when running it takes arguments; ./SyncIPs.cmd 10.0.1.45 and executes few commands.

我试图运行使用的HTML / JavaScript的按钮在JSP页面中此脚本。我到目前为止，两个JSP文件如下：

I am trying to run this script in a jsp page using a html/javascript button. I have so far, two jsp files as follows:

portal.jsp：

portal.jsp:

      <%
      if(request.getParameter("submitted")==null)
  {

    if(check)
    {

        %><%@include file="Sync.jsp" %><%
    }
    else
    {

        %><%@include file="Sync.jsp" %><%
    }   
 }
     %>

Sync.jsp：

Sync.jsp:

   <%
   if(request.getParameter("submit") == null)
   {

   %>
    <div class=display>this is the Sync</div>

    </div>

    <br>
    <form method="POST" action="/project/jsp/Portal.jsp" id=form2>


  <input type=hidden name=sync>
      <!---this is where I want my script to be run from,--->

   <input type="button" value="" name="submit" action="run" 
   onClick="if(runOnSubmit()){getSomethingWithAjax
   ('Portal.jsp'+getAllFormElementsAndMakeIntoURI(true),
   '','hereIsTheMainHeaderSpan',false,false);}">
   <%
   }//end if
   %>

我如何得到这个脚本运行并获得张贴portal.jsp页面上？

How do I get this script to run and get posted on the portal.jsp page?

推荐答案

您必须把一些Java code在你的.jsp

You have to put some java code in your .jsp

try {
  Process p = Runtime.getRuntime().exec("/path_to_your_script/SyncIPs.cmd 10.0.1.45");
  p.waitFor();
  System.out.println("exit code: " + p.exitValue());
} catch (Exception e) {
  System.out.println(e.getMessage());
}
