我知道如何将参数作为mydomain.com?id=2请求传递，但是?id=2我想实现基于正斜杠的方法来在 JSP Servlets 中传递参数，而不是这种方法？

类似于 Stackoverflow：

stackoverflow.com/questions/20425024533/question-title-goes-here

这是我目前拥有的：

JSP 第 1 页

<html>
    <head>
    </head>
  <body>
    <!--Other Page HTML-->
    <a href="PostServlet">Click here to view Post</a>
  </body>
</html>

PostServlet

public class PostServlet extends HttpServlet {

    public void doGet(HttpServletRequest request, HttpServletResponse response)
            throws ServletException, IOException {

        String post_id = request.getParameter("id");

        RequestDispatcher rd = getServletContext().getRequestDispatcher("/BlogPost.jsp");  
        rd.forward(request, response);

    }
}

web.xml

  <servlet>
    <servlet-name>PostServlet</servlet-name>
    <servlet-class>com.myweb.web.servlet.PostServlet</servlet-class>
  </servlet>
  <servlet-mapping>
   <servlet-name>PostServlet</servlet-name>
   <url-pattern>/PostServlet</url-pattern>
  </servlet-mapping>

以 Stackoverflow 格式为例，你能告诉我如何以mydomain.com/questions/id_goes_here/post_title_goes_here.

多谢你们！
