Question

我正在执行jsp下面的命令（例如：shell.jsp），我已经设置了tomcat服务器。我在MAC机器/ mac书中运行。

<%@ page import="java.util.*,java.io.*" %>
<%@ page import="java.lang.Runtime" %>

String unixCommand = "sh /Users/admin/interface.sh";
Runtime rt = Runtime.getRuntime();
rt.exec(unixCommand);

我收到以下错误

An error occurred at line: 9 in the jsp file: /file_upload_download/shell.jsp
**The method exec(String) is undefined for the type Runtime**
   String unixCommand = "sh /Users/admin/interface.sh";
      Runtime rt = Runtime.getRuntime();

Answer 1

我在Windows / MAC上有一个使用公共代码的应用程序。以下是我如何使用它：

Process p = Runtime.getRuntime().exec(<your command>);
InputStream stderr = p.getErrorStream();
InputStreamReader isr = new InputStreamReader(stderr);
BufferedReader br = new BufferedReader(isr);
String line = null;
while ((line = br.readLine()) != null)
System.out.println(line);
int exitCode = p.waitFor();

流读取有助于检查执行的消息。

Answer 2

<head>
<%   
    try{

ProcessBuilder probuilder = new ProcessBuilder（＆＃34; /Users/admin/interface.sh"）;

        Process process = probuilder.start();

        }catch (IOException e) {
            out.println(e.getMessage());
        }        
%>
</head>
<body>

Runtime.getRuntime（）。exec不适用于MAC机器/ mac书中的JSP
