我有一个 JPS 页面，我想从中执行放置在服务器上的 shell 脚本：下面的代码工作正常，并且“/tmp/Sample.sh”脚本正在服务器上执行。现在我想做两件事：1.The script is getting executed as soon as page is loaded, but i want to execute it only when button is clicked.2.I understand that use of scriplets is discouraged, what I googled is that I should call a servlet, when button is clicked, in which i can move the java code.我是这些术语的新手，因为我的主要技能不是 java。我已经阅读了 servlet 的理论，但是没有得到我如何才能实现上述两个功能。对实现以上两点的任何帮助将不胜感激<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title></title></head><body> <% String unixCommand = "sh /tmp/Sample.sh"; Runtime rt = Runtime.getRuntime(); rt.exec(unixCommand); %></body></html>根据建议更新代码：http://10.111.24.21:7001/Project_1/Test_1.jsp<%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%><!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"><html><head><meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"><title></title></head><body><button onclick="location.href = 'http://10.111.24.21:7001/Project_1/JavaServletClass.java';" id="RedirectButton" > Execute</button></body></html>http://10.111.24.21:7001/Project_1/JavaServletClass.javaimport java.io.*;import javax.servlet.*;import javax.servlet.http.*;public class JavaServletClass extends HttpServlet { public void init() throws ServletException { } private void ExampleMethod() throws IOException { String unixCommand = "sh /tmp/Sample.sh"; Runtime rt = Runtime.getRuntime(); rt.exec(unixCommand); }
