如何在WEB-INF文件夹内重定向到JSP [英] How to redirect to JSP inside WEB-INF folder

问题描述

我有一个带有NAV的jsp，它进一步包含以及UL，其中包含以下代码所示的元素，

 < NAV> 
< ul> 
< li class =current>< a>主页< / a>< / li> 
< li>< a>访问控制< / a>< / li> 
< li>< a>网站管理< / a>< / li> 
< li>< a>仪表板< / a>< / li> 
< li>< a>访客管理< / a>< / li> 
< / ul> 
< / nav> 
  

当我点击LI时，我想要做的就是将这个页面重定向到相应的jsp页面。现在因为所有的页面都在WEB-INF文件夹内，所以我不知道如何去做。我不想在WEB-INF的外部创建一个jsp，然后在其中放入servlet重定向代码。提前致谢。

我可以在这里使用什么？

P.S：几个月前开始网络开发。提前致谢。

解决方案

你需要在LI上通过href调用一个servlet。

在servlet中，您需要使用requestdispatcher重定向到您的jsp

  RequestDispatcher dispatcher = getServletContext（）。getRequestDispatcher（ /WEB-INF/sample.jsp）; 
 dispatcher.forward（request，response）; 
  

=================编辑：示例代码=========================================

Index.html

 < nav> 
< ul> 
< li class =current>< a href =/ DynamicTest / MyServlet>主页< / a>< / li> 
< li>< a>访问控制< / a>< / li> 
< li>< a>网站管理< / a>< / li> 
< li>< a>仪表板< / a>< / li> 
< li>< a>访客管理< / a>< / li> 
< / ul> 
< / nav> 
  

Servlet代码

  @WebServlet（/ MyServlet）
 public class MyServlet扩展HttpServlet {$ b $保护无效doGet（HttpServletRequest请求，
 HttpServletResponse响应）抛出ServletException，IOException {
 RequestDispatcher dispatcher = getServletContext（）
 .getRequestDispatcher（/ WEB-INF / sample.jsp）; 
 dispatcher.forward（request，response）; 
 
 $ b保护无效doPost（HttpServletRequest请求，
 HttpServletResponse响应）抛出ServletException，IOException {
 doGet（request，response）; 
} 
 
} 
  

Jsp位置：

  WEB-INF / sample.jsp 
  

I have a jsp with a NAV in it, which further contains and UL with the following elements as shown in the code below,

<nav>
     <ul>
        <li class="current"><a>Home</a></li>
        <li><a>Access Control</a></li>
        <li><a>Site Administration</a></li>
        <li><a>Dashboard</a></li>
        <li><a>Visitor Management</a></li>
      </ul>                
</nav>

What I want to do is to redirect this page to the corresponding jsp page whenever an LI is clicked. Now since all the pages are inside WEB-INF Folder, I cant figure out how to do so. I dont want to create a jsp out side WEB-INF and then put servlet redirection code in it. Thanks in advance.

What can I use here ?

P.S: Started web development few months before. Thanks in advance.

解决方案

You need to invoke a servlet through href on the LI.

In the servlet, you need to use requestdispatcher to redirect to your jsp

RequestDispatcher dispatcher=getServletContext().getRequestDispatcher( "/WEB-INF/sample.jsp" );
dispatcher.forward( request, response );

=================EDIT : Sample Code =========================================

Index.html

<nav>
     <ul>
        <li class="current"><a href="/DynamicTest/MyServlet">Home</a></li>
        <li><a>Access Control</a></li>
        <li><a>Site Administration</a></li>
        <li><a>Dashboard</a></li>
        <li><a>Visitor Management</a></li>
      </ul>                
</nav>

Servlet code

@WebServlet("/MyServlet")
public class MyServlet extends HttpServlet {
    protected void doGet(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
        RequestDispatcher dispatcher = getServletContext()
                .getRequestDispatcher("/WEB-INF/sample.jsp");
        dispatcher.forward(request, response);
    }

    protected void doPost(HttpServletRequest request,
            HttpServletResponse response) throws ServletException, IOException {
        doGet(request, response);
    }

}

Jsp location :

WEB-INF/sample.jsp
