Question

我正在关注以下教程： https://www.javahelps.com/2015/04/java-web-application-hello-world.html

Tomcat服务器在以下设备上运行良好： http://localhost:8080/

此页面正确显示： http://localhost:8080/Hello_World/

但是，当我按“单击此处”并转到此链接时： http://localhost:8080/Hello_World/saytime 显示以上错误。这是我的代码：

package help;

import java.io.IOException;
import java.io.PrintWriter;
import java.util.Date;

import javax.servlet.ServletException;
import javax.servlet.annotation.WebServlet;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

  /**
  * Servlet implementation class HelloWorldServlet
  */
 @WebServlet("/saytime")
 public class HelloWorldServlet extends HttpServlet {
 private static final long serialVersionUID = 1L;

/**
 * @see HttpServlet#HttpServlet()
 */
public HelloWorldServlet() {
    super();
    // TODO Auto-generated constructor stub
}

/**
 * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
 */
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    PrintWriter out = response.getWriter();
    out.print("<html><body><h1 align='center'>" +
    new Date().toString() + "</h1></body></html>");
}

/**
 * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
 */
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    // TODO Auto-generated method stub
}

  }`

我注意到我没有web.xml文件

感谢您的帮助

谢谢，

这是我的HTML代码：

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Hello World</title>
</head>
<body>
<a href="saytime">Click Here</a>
</body>
</html>

HTTP 404原始服务器未找到目标资源的当前表示，或不愿意透露存在的一种表示形式
